Product Details

Entropy Compression Molding Fast Hardener (CPF) is a fast hardener for use with Entropy Compression Molding Epoxy Resin (CPM). The CPM system provides excellent fiber wet out and limits sag in high-temperature cure applications, making it ideal for compression molding processes used to create composite parts. CPM Resin has excellent elongation properties and high modulus, resulting in strong, lightweight composites.

CPF Fast Hardener cures in 20 minutes @ 180°F. All CPM and CPS/CPF hardeners have a bio-content greater than 30% & can be modified with epoxy compatible colorants & fillers. For a slower cure rate, use CPS Slow Hardener. CPF hardener requires the corresponding size of Compression Molding Epoxy Resin (CPM) for use (2:1 mix 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).
