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.
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!
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.

Q:
What is the temperature that the 105 epoxy resin can stand after curing ? Can it stand 500F?
Asked on 5/7/2017 by Katherine from Los Angeles, CA
It depends on which hardener you use, 205 fast hardener is 6 to 8 hours, the 206 slow hardener is 9 to 12 hours.

Q:
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?
Asked on 4/28/2017 by KQMichigan from Grosse Ile, MI
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.
I need to barrier coat a "virgin" fiberglass rudder. Approx 25 SF. What amount would cover this with 3 or 4 coats and will the West System work as a barrier coat?
Yes. 207B is just a small can of 207 hardener which is for clear coat applications. All of the west system hardeners work with the same resin, West 105.
Answered on 1/20/2017 by DAVID LIND from undisclosed
A:
Yes, The West System resin (105) is meant to be used with any of its associated hardners - 205, 206, & 207. The letters following the number relate to the various packaging sizes the produce is available in. Note that the mixture ratio is always the same and is simplified if you use the available pumps for the West System containers. Just mix one pump of resin to one pump of hardner and the pumps are calibrated to provide the correct mixture ratio.

A:
Thanks! I also purchased the pumps . So I'm assuming that it still a one pump for each?

Q:
Can this product be used on my butcher block counter top?
Answered on 12/20/2016 by Robert Becsey from undisclosed
A:
I think it can be used on practically any wood for a nice finish. Just try to apply it as smooth and level as possible. It's quite hard and difficult to sand.
Answered on 12/20/2016 by DALE ANDERSON from undisclosed
A:
Absolutely.. I've made several butcher block counter tops for customers and have used West System 105 epoxy resin with their super clean Hardener, 207. Just make sure that the epoxy has time to throughly dry before using it. I've found that it takes about 5-7 days for the epoxy to really get super hard.
Answered on 12/22/2016 by Don Kerr from undisclosed
A:
Thanks Matt. I'll take your advise and directions
Answered on 12/20/2016 by Robert Becsey from undisclosed
A:
Absolutely. However you need to use the special clear hardener (I believe it's 206). Otherwise it will alter the color of your countertop.
Other thing is you need to thoroughly degrease and de-oil the countertop. I use acetone.
Finally, apply 3-4 coats (without sanding), waiting 3-4hours in between depending on temperature. It will look awesome.
Answered on 12/20/2016 by MATT CRANE from undisclosed
A:
Yes, if it Is a new top without any embedded grease etc. Works best with a roller and a tipping brush. The finish will be bright and smooth but very prone to scratches from utensils. It will not take abuse as well as formica. Good luck Mike
Answered on 12/21/2016 by MICHAEL GORDON from undisclosed
A:
I would not recommend any epoxy for the top surface of a butcher block. This gets hard (obviously) and I feel that chopping on the butcher block will ultimately break off very small amounts of the material and contaminate the food items. These probably would be complete inert once cured and "microscopic" in size, but why not just use a natural food quality oil finish on the surface. If the surface is other than decorative, then I'd go with a quality oil finish. Just my thoughts.
Answered on 12/20/2016 by ROGER HINSDALE from undisclosed
Q:
does west systems have a chart for mixing small amounts 105 with 107. say only 2 oz. ?
59 milliliters of resin for 14 or 15 milliliters of hardener.
One milliliter more or less does not matter. Sometime I just guess it and it always works.
Good luck.
Answered on 12/3/2016 by PHILIPPE PRELATI from undisclosed
A:
Haven't seen a chart. You can mix any amount as long as you get the correct ratio
Answered on 12/3/2016 by RANDY COLKER from undisclosed
A:
I always use the pumps. One squirt is the minimum and that makes less than one ounce of mixed epoxy. Often I need less than that but I just meke one squirt and let the extra get hard in the cup. Or sometimes I have holes to patch or broken cups, etc and use the extra to do those little repairs. The pumps last for many years, stuff never gets hard inside, no waste from measuring cups, no scale needed, etc.

I use West 105 Epoxy with the clear 207 hardener for coating cedar strip canoes with fiberglass. The glass wets out easily, adhesion to wood is great, and the clarity with slight amber color enhances the wood's beauty. Sanding irregularities is hard work, like any resin, so it's worth taking the time to get a good finish to minimise this. The epoxy also makes a wonderfully strong glue if thickened a little to prevent running out of joints.

The packaging system and pumps make it easy to use in the correct proportions, and it needs to be in the correct proportions, it is not forgiving of mistaken mixes. It is possible to get bad results if the ambient temp drops during cure, or humidity gets very high during cure. In the humidity case, the result was a milky appearance and partial cure. In these cases, you need to remove it and start over. I have also had some instances of partial cure, where the "final" result is rubbery. I have found that this epoxy is good for general repairs, especially with coarse cloths and mat, it laminates well to polyester and vinylester when making hull repairs. The powder fillers are dusty and messy but work well for 'fill' repairs and make it easy to sand smooth and flush. This epoxy does not seem to work at all on Teak or Oak wood. It is too viscous and does not penetrate the grain. This results in just a skin coat of epoxy on the wood's surface, which later peels off the oak or teak, like old, blistered latex paint. It worked ok on mahogany and pine/fir. Do not use it in thick coats or try to 'pot' anything, even something tiny, the exotherm will make it smoking hot and you will have a rubbery mess that is hard to clean up. It seems to accept mix-in color pigments fairly well.
