System Three Epoxy
This is the workhorse of the System Three Resins stable, fitting well into over 90% of all epoxy applications. It is a 100 percent solids, unfilled, medium-modulus epoxy system. It works well for new construction and repair, for gel coat blister repair, and for general fiberglass boat repair. Use at a simple 2:1 volume ratio with any of the three hardeners. System Three Epoxy has excellent pot life and cure-time control. Use at temperatures as low as 35 degrees Fahrenheit with no limitations on humidity. System Three Epoxy cures to a very tough, resilient clear film.
The medium-low viscosity of System Three Epoxy allows use "as is" for coating and fiberglass work. Combined with different fillers it is an excellent choice for adhesive, filleting and fairing compounds. When selecting a hardener, consider the minimum temperature expected during application, cure, and the required pot life. Combine different System Three hardeners to provide a continuos range of cure times within the extremes of the fast (#1) and slow (#3).
