BLUSH-FREE 207 SPECIAL CLEAR HARDENER is a wonderful choice for clear coating application. Blended with 105 Epoxy Resin, 207 Hardener is not going to blush or turn cloudy in humid conditions. Thin film applications roll out and tip off smoothly, requiring less sanding in preparation for finish coatings.
THIS WATER-CLEAR EPOXY curing agent used to be developed for coating and fiberglass cloth application where an exceptionally clear, moisture-resistant, natural wood finish is desired. Mix it with WEST SYSTEM 105 Epoxy Resin at a 3-parts resin to 1-part hardener ratio.
STRUCTURAL BONDING PROPERTIES are very similar to other 105/20X resin and hardener combinations. Easily modified with WEST SYSTEM fillers, pigments, and additives to suit a huge number of construction and repair projects, including fiberglass boat repair, strip kayak and canoe construction.
POT LIFE AT 72°F (22°C) is 20 to 26 minutes. Cures to a high-quality state in 10 to 15 hours. Cures to maximum strength in 4 to 7 days. Minimum advisable working temperature is 60°F (16°C). Does not contain VOCs and has moderately high flash point and no solvent odor, making it much friendlier to make use of than styrenated resins.
Pair with WEST SYSTEM 105-A Epoxy Resin
