West System 207 Special Clear Hardener Item # 923176
Description
Features:
- West Systems 207 Special Clear Hardener™ was developed for coating and fiberglass cloth application where an exceptionally clear, moisture-resistant, natural wood finish is desired
- 207 Hardener 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 sand 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
- When 105 Epoxy Resin is used with 207 Special Clear Hardener it 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
