Check the listing for details. System 3 #0103K40 #3 1.5pt General Purpose Dark Amber Epoxy Kit. Condition: New. Listed at 46.95 USD. System Three General Purpose Epoxy is our original product. It actually gave the company its name. From the founding of the company until just a few years ago it has been the workhorse of the product line. The system formulation, containing one resin and three curing agents or hardeners contains a significant amount of renewable materials. Long before "green” was in vogue the System Three General Purpose Epoxy System contained as much as 30% plant derived materials and has never contained any volatile organic compounds (VOC).It has excellent pot life and cure-time control. When selecting a hardener, consider the minimum temperature expected during application and the desired working time. Combine different General Purpose Epoxy Hardeners to provide a continuous range of cure times. Refer to the product datasheet to make a selection. System Three General Purpose Epoxy works great for wood construction and repair, for gel coat blister repair, and for general fiberglass repair. Use at a simple 2:1 volume ratio with any of the three hardeners. Use at temperatures as low as 35ºF with no limitations on humidity. 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 adhesive, filleting and fairing compounds.
