West System 205 Fast Hardener is a low-viscosity epoxy curing agent for use when shorter working and cure time is needed or to provide adequate working time at cooler temperatures.
At 72-degrees, 205 Fast Hardener will have a 9-12 minute Pot Life. When combined with WEST 105 Resin in a five-part resin to one-part hardener ratio, the cured resin/hardener mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties.
Not intended for clear coating.

Questions & Answers about WEST System 205 Fast Hardeners:
2011-12-10A shopper asked: can I mix 205 fast hardner with 207 slow hardner?
+Expand Answers
2011-12-20DANIEL FUNK: I have never done this but i think it would probably work as long as the proper portions are maintained. There's a chance the mixture could shorten the pot life, but i hypothesize that the strength of the bond will not be affected.
2011-12-20J ROBERT KLINGER: yes, but it will harden very fast, faster than the fast hardener alone, and it will generate a lot of heat.
2011-12-20CHARLES SOMELOFSKI: I think it would depend where you live and the temperature you're using it. I would think that you could but it would take a lot longer to cure. Don't mix them together, use the pump and do a 50/50 mix. Do 1 pump of 205 then one pump of 207 to two pumps of resin. I don't know for sure because I've never used the slow hardener
If 17th and 18th century English Admiralty shipbuilders could have used epoxy for frigates, man-o-wars, ships of the line, they would have.

West System would have been used by British Admiralty shipwrights in the 17th century if it were available. I'm glad to be able to use it now.

First time: mix only a small amount-2 or 3 ounces. Use the right ratio! Get a feel for the harding time and your tools.

"Fast" was slower then expected, which was a plus for a difficult glue-up. Loved the despensers; quick, clean, accurate! Easier to use than any previous products. Piano back frame strength is restored and ready for the next century. Ordered another kit for the next job.

Comments about WEST System 205 Fast Hardeners:
I am restoring my 1981 Kelson Hydroplane. We used West System orginally. I feel that one of the reasons the wood in the boat was in such good condition was primarily because of this glue. We mixed West System with 50% Acetone and used it as a wood seal (two coats). After 25 yrs the wood is still NEW in appearance and color. Fantastic Product

Comments about WEST System 205 Fast Hardeners:
At the lower range of use temperatures, I found it helpful to put heat lamp on wet epoxy to reduce the cure time. Otherwise its several days to cure. Biggest drawback with this product is its price. Like all epoxy, it's messy and you need to be prepared to work with it by using proper application and protective equipment.
