West System 207 Special Clear Hardener

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
