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.
