Entropy Clear Slow Hardener (CLS) is used to extend working properties and cure time when mixed with Entropy Clear Laminating Epoxy Resin (CLR) or Optically Brightened Laminating Epoxy Resin (BRT) for laminating wood, fiberglass, carbon fiber, or Kevlar. These premium resins are used for hand layup, room-temperature processes, or infusion laminating.
This biobased resin system exhibits low color, excellent air release, and exceptional UV and color stability. Use with CLR resin or BRT resin for long pot life and low exotherm lamination and coatings. Resin and hardener combined have a bio-content greater than 30%, and can be modified with epoxy compatible colorants and fillers.
Requires corresponding size of Clear Laminating Epoxy Resin (CLR) or Optically Brightened Laminating Epoxy Resin (BRT - bright white) for use (2:1 mix ratio). See chart below.
