Product Details

207 Special Clear Hardener was especially developed for use with West System 105 resin in coating applications where an exceptionally clear moisture-resistant natural wood finish is desired.

Improved formula chemistry allows for true clear cure with same UV stability without amber tint. An ultraviolet inhibiting additive improves the resistance of a West System 105/207 mixture to sunlight but the cured epoxy surface will still require the additional protection of a quality UV-filtering varnish.

207 is designed to self level for smooth finishes and to wet-out and bond fabrics. Although it provides good physical properties for general bonding applications, it is more difficult to thicken and less cost effective for this purpose than 205 or 206 hardeners. It's also used for laminating veneers where bleed through at joints may be exposed to sunlight.

Best I have ever used
By Steve Boatguy from Clearwater, FL

Verified Purchase

I have been working with epoxy for nearly 40 years and have tried just about all the major manufacturers. I always come back to West because they have the widest line of products. The 207 hardener has proven its superiority in work that is over 25 years old. I'm sticking with West from now on.

Bottom Line Yes, I would recommend to a friend

By Don C. from TN

I have used many other epoxy systems and have issues with amine blush and washing it off. I really like not worrying about it with this product. An excellent hard clear finish.

Packaging
By Bull Run Canoes from Gainesville, VA

Awesome product, but I did not necessarily like how it was packaged. JD placed a strip of packing tape over the cap which extended onto the sides, to keep the integrity of the cap I suppose so there was no chance of spillage, awesome idea. BUT, when I tried to remove the tape from the can, it removed the portion of the can that contained the safety information, basically ripped the manufacturer's label off in the process. The tape is see through enough so I did not try to remove and more but possibly next time use crystal clear tape.

Bottom Line Yes, I would recommend to a friend
