Resin Cotton Microfibre Filleting Blend Fairing Blend Fibreglass Tape
Glass Balloons Solvent Plywood Scarf Joint Filleted Chine Joint Terms and Conditions

UK Epoxy Marine Resin is a solvent free resin system for bonding ,filleting, filling , composites and coating.

For all applications the mix ratio is 2 parts of resin to 1 hardener by weight or by volume using our calibrated pumps.

Working temperature range

 
Working temperature range 12 to 25 degrees Centigrade. If you cannot maintain this temperature range the system will still work, it will just take a little longer to cure. If you can heat the resin and hardener containers in hot water or a heated box it will help in dispensing, mixing and curing. Try to maintain a temperature of 12 to 25 degrees "C" for at least 2 hours after the joint is closed whilst the initial chemical bonds are forming. Do not store resin very low temperatures, as waxing or crystallisation can take place. It appears as a wax like layer at the bottom of the resin container it is not detrimental to the resin and can be removed by placing the container in hot water ( tap hot not boiling) as the resin warms the wax or crystals dissolve back into the resin
 

 Mixing

 
It is extremely important that the resin and hardener are mixed thoroughly a mixing time of two minutes is recommended. If using measuring pumps ensure that the resin and hardener are warm and the same temperature, in cold conditions stand containers in hot water. If the resin and hardener is allowed to go cold it is possible that the mix ratio may vary. Do not be tempted to add more hardener as this will not reduce the cure time but will weaken the final resin structure and it may not fully cure at all
 

Based on the 15 to 20 degree temperature range curing times are as follows

 
Pot Life 45 to 35 minutes This is the workable life of the resin system
   
First stage 4 to 7 hours This is the thin film cure time and and should be dry to the touch ( Nail Hard When impressed with a thumbnail it will leave a mark)
   
Second stage 24 hours  This the resin cure point and it has reached almost full cure and should now be completely hardened to a clear finish across the coated surface
   
Third and final stage 7 Days  This is the time taken for the last 1.5 to 2 % of curing to take place it is recommended that you do not attempt to apply paint or varnish to an epoxy coated surface before this time has elapsed
 
Depending on the temperature the resin will go from a "Gel" state to a solid within 4 to 7 hours and the cross linking of the resin and hardener will have started, at this time it will be possible to indent the mix with your finger nail. You can at this stage apply a second coat of resin/hardener mixture or the application of a filleting mix over a bonding mix or the addition of a woven glass tape over the filleting mix without any further preparation
.
 Amine Blush.
Under normal working conditions our resin system is blush free. If you are using the resin system in really extreme cold damp winter conditions amine blush may occur. This is a waxy film that can coat a finished laminate or resin layer and it is the reaction between the moisture in the air and the amine structure of the hardener. There are two ways of dealing with this problem one method is to heat the workplace to 15° to 20° C and keep it completely dry, or you can simply work in the conditions you have and if when your resin has cured you get amine blush on the surface wash it away with a few drops of washing up liquid in a bucket of warm water and this will remove it, washing the epoxied surface prior to sanding is good practice.
Safety Precautions
It is recommended that you ensure that there is sufficient ventilation of the area where you are working and to avoid direct contact with the resin system on your skin

Pure Milled Cotton Microfibre " Colour off White"

 
Cotton fibre is made from cotton fibres milled to to a fibre length of not longer than than 0.2 mm in length and can be used on its own or combined with other fillers, it is highly absorbent and thickens resin well. Up to 30% by weight can be added to the resin/hardener mixture. Cotton fibre acts as a reinforcement and prevents resin starvation in the areas to be bonded. The final hardened mixture has immense strength and can be used in all structural applications above and below the water line.
 
When you are creating a joint such as an angled chine on a stitch and tape plywood hull the cotton fibre mix can be used as the initial bonding adhesive .Its main use is in strip plank construction and general joinery where the fibres not only add strength but act as a reservoir for the epoxy especially on porous woods.

High Density Filleting Blend

 

A combination of cotton fibre, wood flour ( not sanding dust ) and other fillers in a blend to give an easily smoothed fillet of extremely high strength. High density filleting mix can be used on its own for edge bonding as in strip planking applications, or as a high strength interior and exterior filler above and below the water line, the interior fitting of bulkheads and is the basis for the high strength fillets required in stitch and tape construction.

 
Mixing

When mixing add only enough high density filleting blend to make the resin/hardener mixture thick enough not to to sag on vertical surfaces but maintaining a wet sheen on the surface, so that a smooth surface is achievable without dragging. If you have made the mix a little dry and you get a rough surface finish finish that is not going to be covered with fibreglass tape wait until the fillet has cured, lightly sand the fillet and apply a single coat of unfilled resin/hardener mix this will cure to a smooth finish.

 

The High density fillet is applied with a mixing stick or plastic applicator shaped to a radius that will allow the smooth application of glass tape about 30 mm will do on 9 mm ply, on thicker ply increase the size of the radius to about 3 to 4 times the ply thickness. Allow this layer to set until it is no longer tacky and is quite firm usually about 3 to 4 hours at 12 to 15 deg "C" . Then the Woven Glass Tape can be applied. If the fillet is allowed to reach full cure the surface should be sanded and prepared, prior to the application of the fibreglass tape.

Fairing Blend

 
A combination of Micro-Balloons, and other fillers its colour is shown in the bar above, it is extremely light in weight. Approximately half the weight of the high density fillers
 
Mixing
Add Fairing blend to resin/hardener mix to the required consistency that will not sag on vertical surfaces
 
Using
If being used on a cured resin coated surface the area to be filled should be well sanded and primed with resin/hardener, on bare wood a coat of resin/hardener mix will ensure an excellent bond. Trowel the fairing mix onto area to be filled and leave it just proud of the surrounding surface, when cured it can be sanded to a fine finish. It can be used instead of High Density Filleting Blend in stitch and tape chine joints when lightness of construction is important such as lightweight canoe's. Fairing blend can also be used for decorative fillets on interior construction or in conjunction with woven glass scrim tape for higher strength.

Glass Balloons
Description
A white powder non water permeable and are of an irregular interlocking shape and when mixed with resin/hardener the irregular shapes provide advantages both as a lightweight filler and reinforcement. The finished resin is non water permeable, the balloons can be added to resin up to 30% by weight. The composite density at this ratio is approximately 0.52 g/cc.
Glass balloons can be added to other fillers to make them both lighter and more easily sanded

Tool Cleaning Solvent and Thinners

 
Tool Cleaning solvent can be used for general cleaning of uncured resin, brushes and rollers it is recommended that protective gloves be worn when using.

The solvent can also be used to degrease surfaces after sanding prior to the application of resin.

When used for brush and roller cleaning during the work period you simply pour 20 to 30 mm depth into a lidded container tall enough to accept your brushes, I use the tall coffee jars. Place the brush or brushes into the jar and work them into the solvent, close the lid and leave until next required. At the end of the work period work into the used solvent and then clean with fresh solvent in another container finally store in a clean lidded container with a small amount of solvent to keep the brushes soft until the next day
.
For our mini rollers to clean and prevent hardening during work period work the solvent into the fibres and store in a lidded container with 20 to 30 mm of solvent in the bottom, shake the container occasionally this will enable the rollers to last for several days.

Prior to using a cleaned roller squeeze out surplus solvent and dry the roller by rubbing on a piece of clean scrap timber.

The solvent can be used as thinners to lower the viscosity of the resin/hardener mix. You can add up to 5% by weight without impairing the integrity of the resin system. It is useful to use when trying to penetrate to great depth in old or damaged timber, shakes, cracks etc.

Scarf Joint

 
Cutting A Plywood Scarf Joint
 
Place both sheets to be scarfed as shown in the diagram above with "A" being 6 times the plywood thickness. The edge of the lower board should be supported across the full width of the sheet. Place the second sheet on top of the first set back 6 times the plywood thickness in the case of 4 mm ply this would be 24 mm mark a line on the top sheet equal to the step between the sheets measurement "A" and clamp the sheets together. Now with a low angle block plane remove the triangular areas shown in white working evenly across the scarf until you have reached the line on the upper sheet and the scarf tapers evenly down to a feather edge on the lower sheet.
 
Epoxy bonding a plywood scarf joint
 
Lay a piece of polythene or waxed paper across the lower support block and lay the left hand board on it as shown in the above diagram now apply UK Epoxy Resin/Hardener mix filled with High Density Filleting Blend mixed to a creamy consistency to the angled scarf. You may wish to pre-coat both of the angled scarf's with plain resin/hardener mix to fill the grain prior to applying the filled resin system. Now slide the second sheet up to the first taking care not squeeze all the resin out of the joint, at this point panel pin both sheets down to the lower support block if you wish to prevent them sliding apart during the clamping making sure to leave sufficient amount of the panel pin sticking up to enable easy removal the holes can be filled with filled epoxy.. Now place a second sheet of polythene or waxed paper on top of joined sheets place a block of wood on top the full width of the scarf and apply pressure with clamps or heavy weights. Leave for 24 hours then remove weights, clamps and blocks sand both sides and you will have an almost invisible joint stronger than the surrounding plywood.

Chine Joint Using Stitch and Tape Method

 
 Wired Chine joint This is the method for joining the shaped planks of a plywood hull it consists of stitching and edge bonding the shaped plywood planks to create a finished hull.
The first operation is to apply the stitches you can use copper wire or plastic cable ties the cable ties do give you more control when bringing all the planks together as they can all be fitted loosely and then gradually tightened both closing the gaps and bringing the hull to the correct shape.

The image on the left shows what you are aiming for
Wired and filled Chine joint The next stage is to apply the fillet shown in yellow this is a mixture of Epoxy Resin/Hardener and High Density Filleting Mix which you can read about further up the page. It is better to prime the surface with Resin/Hardener before you start to apply the fillet to insure maximum bond strength, You can shape the fillet with anything that is the correct radius, a plastic squeegee with the corner cut of and radiused is ideal.
Filler may squeeze through any gaps in the planks so sealing the outside of the seams with parcel tape will help to prevent drips on the floor and also assist partly in filling the outside part of the chine joint.
Wired filled and taped Chine joint After four hours at 20 deg C the fillet will have become dry to the touch but if you pressed with you finger nail you would leave an impression this is the time to apply the fibre glass tape. This done by first priming the area to be taped with resin/hardener then laying the tape on the wet resin. Further resin is applied to thoroughly wet out the tape being careful not to disturb its position.
After a couple of hours the tape will be ready to squeegee down to expel any trapped air this will show as white areas but being careful not to disturb the position of the tape or pressing to hard so as to squeeze the resin/hardener out of the fibres of the fibre glass. After twenty four hours the resin should be cured and you can now progress onto the outside of the hull.
Completed Wired Chine joint When all of the inside of the hull is filleted and taped and has fully cured the parcel tape can be removed from the outside of the hull and the outer part of the stitches cut off. The outside of the seams is now filled with High density filleting mix and resin and allowed to cure fully. The outer seam can now be sanded smooth and given a radius so that the fibre glass tape will flow over the angles of the planks and not entrap any air.
The same procedure is now followed as per the inside of the hull to apply a layer of fibreglass tape to the outside of each of the seams.
