Entropy High Bio-Based Slow Hardener
This item is eligible for free shipping
Formerly known as Super Sap ONS, Entropy's High Bio-Based Slow Hardener is the slow cure rate catalyst for their High Bio-Based Laminating Epoxy Resin (ONE) system. As the industry's First USDA Bio-Preferred Certified liquid epoxy resin product, this epoxy system delivers it all: high bio-renewable content, a green resin with room temperature cure, and low sensitizing ingredients for increased user safety.
Its relatively low viscosity and great adhesion to all substrates makes High Bio-Based Epoxy excellent for composite laminating, and it features air release additives that allow for smooth brush-on coatings.
Hardener requires corresponding sized High Bio-Based Laminating 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).
WARNING: This product can expose you to chemicals, including propylene oxide, which is known to the State of California to cause cancer. For more information go to www.P65Warnings.ca.gov
