Mix General-Purpose #2 Medium Epoxy Hardener with General-Purpose Epoxy Resin (e.g. #77380, sold separately) for approximately 30 minutes of working time, tack-free resin within about 4-6 hours and a minimum application temperature of 55°F. General-Purpose Epoxy is the original epoxy resin system that gave the company its name—one resin, three hardeners: ''System Three.'' From the beginning, the General Purpose Epoxy System has been free of volatile organic compounds (VOCs), and has contained as much as 30% renewable plant-derived materials. Since Resin and Hardener are sold separately, you get tremendous flexibility when it comes to desired cure time, pot life and the minimum application temperature expected in your shop. Different Hardeners can even be mixed together to provide a continuous range of cure times. Refer to the the Specifications and/or the product datasheet for more complete info on selecting/mixing your Hardener.

Features:

  • Requires General-Purpose Epoxy Resin (e.g. #77380, sold separately)
  • No volatile organic compounds—up to 30% plant derived materials
  • Convenient 2:1 mixing ratio
  • Unfilled; solvent-free formula
