THIS WATER-CLEAR EPOXY curing agent was 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.
Pot life when stored at 72°F (22°C) is within the range of 20 to 26 minutes. Solidifies completely within 10 to 15 hours. Reaches maximum strength within 4 to 7 days. Best working temperature is at least 60°F (16°C). Free of VOCs, with a high flash point and no solvent odor, making it a safer alternative to styrenated resins.
BLUSH-FREE 207 SPECIAL CLEAR HARDENER is an excellent choice for clear coating application. Blended with 105 Epoxy Resin, 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.
STRUCTURAL BONDING PROPERTIES are similar to other 105/20X resin and hardener combinations. Easily modified with WEST SYSTEM fillers, pigments, and additives to suit an enormous variety of construction and repair projects, including fiberglass boat repair, strip kayak and canoe construction.
