Entropy Super Sap CLF Clear Fast Hardener

Entropy CLF Clear Fast Hardener is used when faster curing of biobased Entropy CLR Clear Resin or Entropy BRT White Resin is desired or when working in colder temperatures. The CLR Clear Epoxy system is water-clear; the BRT system is 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 excellent air release, low color, and exceptional color and UV stability.

Use with Super Sap CLR Clear Resin or bright white BRT Resin for medium pot life & low exotherm lamination & coatings. CLR and BRT resins & CLS/CLF/CLX hardeners have a biocontent greater than 30% & can be modified with epoxy compatible colorants & fillers.

Safety and Handling Information

Despite the natural derivation of Entropy resin products, exposure to these materials represents hazards typical of all epoxy resins. Exposure should be minimized and avoided through the use of proper personal protective clothing & equipment, and appropriate manufacturing controls. All persons who use, store, or transport these materials should understand proper handling precautions and recommendations, as stated in the SDS (safety data sheets).

good clear epoxy option

The CLX hardener would be good to have. i mix the two to adjust cure times.

this product is so easy to use, I also used the pump for the bottles and they make it so easy to measure out the proper mix. I am building wooden bait tanks to hold bait fish, I built the out of 3/4" plywood and then used Entropy CLR Clear Resin with the slow hardener. This gives you lots of time to lay your fiberglass matt down and mix more if you are running short when you add a coat to your matt. Once you paint your matt with using a short bristle brush, use a plastic spreader board to smooth out wrinkles in the matt. It will dry to a clear finish. And it is paintable.

Excellent, so far....

Super Sap CL/F is an excellent system, as far as I have tested it for strength and workability in composite laminates. The only testing left to do takes time - we all know how epoxies can become brittle and weaken, especially in marine applications. It's great for now, and for the final results, we wait....
