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.

Been using West 207 for many years under a 2-part polyurethane (Epifanes for more than a decade, Interlux Perfection before that) on my south facing deck. Builds quickly and can apply 3 coats in one day, generally all that's needed. Deck looks great after all these years with occasional maintenance (about 5 years in sun, double that in shade). Wood is western red cedar.

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.

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.
