Entropy Super Sap CLR Clear Epoxy Resin

Entropy Super Sap CLR Clear Epoxy Resin is the base component of Entropy's CLR low-viscosity, low-color, UV-stable system for composites, coatings & adhesive applications.

It's optimized for hand layup, room temperature processes, or infusion laminating of wood, fiberglass, carbon, or Kevlar. It's air release and UV protection create clearer cured laminates with excellent color stability.

CLR resin forms a hard plastic surface when cured with Super Sap hardeners: CLS slow hardener offers long pot life, CLF fast hardener offers shorter pot life and faster curing, and CLX hardener has the fastest tack-free time. The CLR system has a bio-content greater than 30% & can be modified with epoxy-compatible colorants and fillers.

NOTE: For white cosmetic applications, use Super Sap BRT Clear Epoxy Resin, which uses the same hardeners as the Super Sap CLR system.

Why Use Super Sap®?

Super Sap formulations, as opposed to traditional epoxies that are composed primarily of petroleum-based materials, contain renewable, biobased materials sourced as co-products or from the waste streams of other industrial processes, such as bio-fuels and wood pulp production. The benefits of these natural components are exceptionally high adhesion properties and excellent elongation.

Three Easy Ways to Measure Super Sap Resin and Hardener

  • By Volume: 2 parts resin to 1 part hardener.
  • By Weight: Varies. Check Technical Data Sheets for specific ratio.
  • By Pumps: The calibrated Entropy Pump Set (sold separately) measures the exact 2:1 ratio by volume with no mess or guessing about correct measurements, so you get a proper cure every time. Pumps can be used with the 2:1 Super Sap ONE, CLR, BRT, CPM, and CCR Resin Systems.

Measuring & Mixing Notes: For best results, use a scale to measure the two components by weight (within 5% of the recommended mix ratio). Always mix product thoroughly for at least two minutes. To ensure complete mixing, scrape all surfaces of the container.

IMPORTANT: Super Sap CLR works better in low-humidity environments, especially when it's used outside of the recommended optimal temperature range. See specific temperature ranges in Application Tips.

Entropy CLR Resin Features

  • Crystal clear color is ideal for clear coating applications
  • Choose from Extra Fast (CLX), Fast (CLF), and Slow(CLS) Hardeners to adjust working properties and cure time
  • UV stable formula
  • Low exotherm
  • Excellent air release
  • Requires corresponding sized CLX (Extra Fast), CLF (Fast) or CLS (Slow) hardener for use (2:1 ratio). See chart below.

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).

          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....
