WEST System 207 Special Clear Hardener

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.

Packaging

5

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.

Use this hardener when you will be clear coating and UV is a concern.

High Quality Product

This is an awesome product. I have yet to discover what can be done with it. Adding fillers and coloring agents, repairs to center boards, hulls and other plastic, fibreglass parts become an easy project. Due to wood out gassing, my current restoration ( Mahogany) project has been quite difficult. Attempts for help have been frustrating. Overall I am very happy with this product.

Couldn't unscrew lid

Thanks for a chance to respond, the 207 hardener wasn't able to open. The screw on lid was adhered to the "flange" and that was spinning around, there had been some leakage during shipping. I was unable to open the lid correctly, not sure if it was West Systems or Jamestown's doing but it made application harder. Finally just had to punch two holes in it and pour it out that way, wish I could of used my pumps though...It seemed I lost about a quarter of the can during transit. Other than that, you're all great. Talk soon.

Nice Finish, Be Aware of Product Change

5

I like this product for exterior use under a varnish. In my own tests it at least doubles the life of the varnish.Be aware that West is changing 207 from "Special Coating Hardener" to "Special Clear Hardener" under the same part number. The new product drops the Amber tint. Normally this isn't a big deal but if you are caught in the middle of a project and switch there can be a noticeable difference. It would be nice if West would have a tint additive if you wanted to continue using the Amber product (which is discontinued in production) much the same as Crystalac does with its warm dye toner, which changes the clear to traditional varnish tone.
