WEST SYSTEM
#207 Special Coating Hardener

207 Special Clear Hardener is formulated for coating and fiberglass cloth application where an exceptionally clear, moisture-resistant, clear carbon fiber or natural wood finish is desired. Mixed with 105 Resin at a 3:1 ratio, it will not blush or turn cloudy in humid conditions. Thin film applications roll out and tip off smoothly, requiring less sanding in preparation for finish coatings. Professional and first-time builders like 207 because it is reliable and easy to use. Three coats or more can be applied in one day without additional surface preparation. Fewer coats are required to fill fiberglass weave and in most cases the final coating can be sanded the following day. Boats can be built faster. Builders also appreciate the excellent fiberglass wet-out characteristics achieved with 105/207, yet it won't drain from vertical surfaces like the very slow curing, low-viscosity epoxies. 105/207 has strong physical properties, so it can be used as a structural adhesive for gluing and laminating. It has excellent compatibility with paints and varnishes. An ultraviolet inhibitor in 207 helps provide a beautiful, long-lasting finish when used with quality UV filtering varnish. 105/207 cures clear and colorless.

  • 207 SA-size hardener should be paired with 105 A-size resin.
  • 207 SB-size hardener should be paired with 105 B-size resin.
  • 207 SC-size hardener should be paired with 105 C-size resin.

      Great clear coat for white oak

        Comments about #207 Special Coating Hardener:

        I used this product to coat the white oak cheeks on my sailboat rudder. Sanded the wood, cleaned with acetone, breifly heated with heat gun, mixed small batch well in paper cup, applied with a squeegy and pressed into wood grain. I reapplied a few more coats when the epoxy started to kick - no sanding between coats. After everything hardened, I drilled slightly oversized holes for the bronze through-bolts, filled with thickened expoxy, and after it set drilled appropriate bolt holes. I then covered everything with a few coats of varnish to provide UV protection and assembled. I lightly sand and reapply varnish once a year. After three years, the cheeks still look great!

            this is the first time i have used real epoxy resin, and i was expecting it to be super difficult. but it went on clean, dried slow enough for me to work with it. doesn't smell bad like the bondo stuff.

                I'm using this product with 105 resin and carbon fiber cloth. I like that it's water clear. It's as easy to use as any hardener/resin system. I have not had the problem of leaking cans that another reviewer noted.

                Comments about #207 Special Coating Hardener:

                better than advertised. only downside is that the cans leak and this stuff isn't cheap. maybe go to plastic packaging like some of the others. 4 out of 4 cans of the 207 have leaked. one can leaked almost the whole contents before i found it. cans arent damaged. they just leak. [...]. The product itself is excellent.

                    We use West System epoxy to embed small objects in wood. The new formula is water clear, and always provides a durable casting.
