Entropy Clear Extra Fast Hardener (CLX) provides the fastest cure time for the Clear (CLR) and Optically Brightened (BRT) laminating epoxy systems. The CLR system is water-clear; the BRT system is bright white.
Both are low-viscosity, UV-stable liquid epoxies for composites, coatings & adhesive applications, and are optimized for hand lay-up, room temperature processes, or infusion laminating of wood, fibers, glass, carbon, or Kevlar. All Super Sap resins exhibit low color, excellent air release, and great UV & color stability.
Use CLX Hardener with CLR or BRT resins for fastest cure time at room temperature. CLR and BRT resins, as well as CLS/CLF/CLX hardeners have a bio-content greater than 30% & can be modified with epoxy compatible colorants & fillers.
