WEST System Epoxy cures to a high-strength plastic solid at room temperatures, by mixing specific proportions of liquid epoxy resin and hardener.
This clear, pale yellow, low-viscosity liquid epoxy resin is formulated for use with WEST SYSTEM hardeners. It can be cured in a wide temperature range to form a high-strength solid with excellent moisture resistance.
Designed specifically to wet out and bond with wood fiber, fiberglass, reinforcing fabrics and a variety of metals, 105 is an excellent adhesive that will bridge gaps and fill voids when modified with WEST SYSTEM fillers. It can be sanded and shaped when cured. In roller applications, it has excellent thin-film characteristics to flow out and self-level without fisheyeing. 105 resin has a relatively high flash point and no strong solvent odor, making it safer to work with than polyesters.

By using a simple "cookbook" approach you can tailor the handling characteristics and the physical properties of the cured epoxy to suit your working conditions and specific coating or bonding application.
1. Start with 105 Resin, the basic ingredient of all WEST SYSTEM epoxy compounds.
2. Mix with one of four WEST SYSTEM Hardeners. Select a hardener for its intended use and for the cure speed best suited for your job in the temperature range in which you are working.
3. Add one of six WEST SYSTEM fillers to thicken the mixture as needed. Select a filler for its handling characteristics or cured physical properties. Or, add one of six WEST SYSTEM additives to provide specific coating properties.

My project is to coat the iron keel on an '86 boat. POR15 seems to get good ratings online for stopping rust. My thought is to overcoat the POR15 with West System, but will it stick to POR15 ? PS I barrier coated a badly blistered bottom with lead keel using West back in the 80's. It still looks great today!
Gil
I'm not familiar with POR15. I would recommend testing a small area with that and West System to see if there are any problems.

will using 105 epoxy and 206 hardener create a clear or amber fiberglass lamination for bow limbs?
none
The 206 hardener is a little amber, if you want it to be clear use the 207 Clear Hardener.
JD Tech Team
I would like to build a bow for my grandson, and making my own fiberglass laminations. Would your 105 epoxy resin be a good choice. Will be building a bow oven so heat curing will not be a problem should that be necessary.
bender
Since a bow needs to flex, a better choice would be West System GFlex or Totalboat FlexEpox.

It will work to glue it together.

I need to fill knot holes in a white oak plank floor. 1200 sq ft of floor. New floor. Any suggestions?
george
If you are looking for it to be clear, use this resin with the 207 clear hardener.
JD Tech Team
Sounds like this might be good for old tongue and groove hardwood flooring with large gaps. Thinking bathroom/kitchen where 1/16-3/16 gaps cause problems. Needs to withstand expansion due to moisture changes. Needs to be sandable and tintable. Regular wood/flooring fillers don't work long enough. Any thoughts? Thanks!
Tim
Regular epoxy is hard and brittle and won't do well with expansion and contraction. I'd suggest TotalBoat Thixo Flex Flexible Epoxy Adhesive Upon cure, it creates permanent, structural bonds that absorb shocks, stresses, & vibration. This cartridge-dispensed non-sagging epoxy is great for building or restoring wooden boats prone to flexing during use, and movement from weather-related expansion & contraction.
JD Tech Team
What is the temperature that the 105 epoxy resin can stand after curing ?Can it stand 500F?
Katherine
No.
JD Tech Team
How long does it take for 105 resin and slow hardener (air temperature 80 deg. F) to cure enough to grind and re-coat?
Bruce
It depends on which hardener you use, 205 fast hardener is 6 to 8 hours, the 206 slow hardener is 9 to 12 hours.

I purchased this 8 months ago and it worked brilliantly. I store the leftover in my garage which briefly reached a nighttime temperature in December of about 40 degrees F. Then I moved it into indoor storage. Now it is not hardening when I used the recommended pump measurements. After waiting several hours, I stirred in another single pump of hardener. Still would not harden. Has it gone bad?
KQMichigan
It should still be good. Usually when we hear that it isn't curing it's because the mix was 5 pumps of resin and one pump of hardener. The correct mix is one pump of resin to one pump of hardener. Adding more hardener will not cure any quicker and may not cure at all.
JD Tech Team
will it work on phenolic sheets?
jack
Yes, that should work.

Easy to use epoxy

I've used West System Epoxy for several lap strake boats I've built. With the associated pumps it's easy to mix up small batches and easy to apply. My shop is cool in Northern, Vermont, but I always got a good cure by leaving heat on for a few hours. I simply let the wood fire go out and come back a few hours later to the shop and turn off a couple Mr. Heater tank top heaters.

West system is a great epoxy

After trying a few of the other brands, I decided to try west systems. This product has a much lower viscosity rating, making it easier to penetrate those small cracks. The epoxy is easy to thicken with a variety of fillers and takes dye well. I would also recommend using the metered pumps as they make mixing this epoxy a dream.

Good product

I commented on the hardener and the comments apply to the resin as well. Buying it from Jamestown is considerably cheaper than getting it from the local marinas. I have mixed feelings about taking business away from the local store that I often depend on for items or advice, but price is certainly a consideration.

I build a wide variety of things and I am very happy with the WEST system. There are few surfaces that epoxy will not bond well to.

the resin was fine except underneath it was my six plastic syuringes and the 210 filler both damaged they made it right but like I always say never got time to do it right always got time to do it over

Used to seal Numerous teak and mahogany wood for boat applications. Worked extremely good on Mahogany rails to fill the grain quickly. Can not speak for durability yet
