Entropy High Bio-Based Fast Hardener (ONF) is the required fast cure rate catalyst for Entropy High Bio-Based Laminating Epoxy Resin (ONE).
As the industry's First USDA BioPreferred Certified liquid epoxy resin product, the High Bio-Based Epoxy system delivers it all: a high bio-renewable content, green epoxy resin with fast room temperature cures and low sensitizing ingredients for increased user safety.
Its relatively low viscosity and great adhesion to all substrates makes it an excellent composite laminating resin and it features air release additives that allow for smooth brush-on coatings. This is the eco resin of choice for consumers.
Requires corresponding sized High Bio-Based Laminating Epoxy Resin (ONE) 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).
