Product Details

Entropy Clear Casting Epoxy Resin (CCR) is a low-viscosity, pourable liquid epoxy designed specifically for casting, embedding, and coating applications. It exhibits low color, excellent air release, and UV stabilizer technology for crystal clear products with excellent color stability.

All Entropy systems employ the lowest sensitizing ingredients for increased user safety, which makes CCR a great eco resin for any art or hobby project. CCR is available in two hardener speeds. Slow hardener (CCS) is best for applications greater than 1" thickness due to low exotherm. Fast hardener (CCF) should ONLY be used for low build casting applications with thicknesses BELOW 1" for long pot life and low exotherm. Both systems have a bio-content greater than 30%, & can be modified with epoxy compatible colorants and fillers.

Info & Guides

Why Use Clear Casting Super Sap® Epoxy Resin?

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 Clear Casting Epoxy 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 High Bio-Based Epoxy Resin (ONE), Clear Laminating Epoxy Resin (CLR), Optically Brightened Laminating Epoxy Resin (BRT), Compression Molding Epoxy Resin (CPM), and Clear Casting Epoxy Resin (CCR) 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.

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).

WARNING: This product can expose you to chemicals, including epichlorohydrin, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to
