Wide Range of Working Temperatures A 100% solids, medium modulus epoxy system that works well in 90% of all epoxy applications. It is great for wood construction and repair, gel coat blister repair, and general fiberglass work. Use at a simple 2:1 ratio with any of three hardeners - allowing excellent pot life and cure-time control. Can be used at temperatures as low as 35°F with no limitations on humidity. When selecting a hardener, consider the minimum temperature expected during application and the required pot life. If required, a mixture of 2 hardeners will provide extra fine tuning for cure times. The medium-low viscosity of System Three General Purpose Epoxy allows for use "as is" for coating and fiberglass work. Combine with different fillers to make excellent adhesive, filleting and fairing compounds.
