Entropy Super Sap CLR Clear Epoxy Resin

Bio-based CLR Clear Resin is the base component of Entropy Super Sap Clear All Purpose Epoxy, a low viscosity, low color and UV stable liquid epoxy system for composites, coatings, and adhesive applications.

Super Sap CLR is optimized for hand lay-up, room temperature processes, or infusion laminating of wood, fibers, glass, carbon, or Kevlar. Like all Super Sap resins, CLR exhibits low color, excellent air release, and UV stabilized technology which produces clearer cured laminates and coatings with excellent color stability.

Entropy resins form hard plastic surfaces with strong bonds when cured with Super Sap hardeners. Use CLS slow hardener for long pot life or the CLF fast hardener for shorter potlife and faster curing. Both systems have a Bio-content greater than 30%, and can be modified with epoxy compatible colorants and fillers.

No Compromises. Performance, Sustainability, Lower Environmental Impact.

The mission at Entropy Resins is to provide epoxy resin systems for a new generation of products. Products that not only perform, but also take a crucial step towards lowering our impact on the environment.

Entropy Resins produce epoxy systems engineered to meet or exceed the performance standards of petroleum based resin systems with a focus on environmentally sustainable production. Environmental benefits include bio-based content sources and a reduced carbon footprint. Super Sap uses a pine pulp based resin sourced from by-product of paper manufacturing processes and plant based byproduct from bio fuels processing.

      Comments about Entropy Resins Entropy Super Sap CLR Clear Epoxy Resin:

      Used Entropy Resin and Hardener to fiberglass a cedar strip canoe. Easy to mix and use, super clear, and doesn't smell bad. The best part is it hasn't had any problems curing even though my shop is on the cold side.

        Comments about Entropy Resins Entropy Super Sap CLR Clear Epoxy Resin:

        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....
