Trifunctional Aziridine Crosslinker

Polyfunctional aziridine crosslinker sac-100

Crosslinker sac-100 is a 100% active, polyfunctional aziridine liquid crosslinker. Additional of 1-3% to water based acrylic emulsions or urethane dispersion produces a marked improvement in water, chemical, abrasion and humidity resistance and enhances adhesion to specific substrates. Crosslinker sac-100 is room temperature reactive and therefore can be used under air and forced drying conditions.

Recommendations for end-use
-in water based parquet lacquers to improve water, alcohol, detergent, chemical and abrasion resistance.
-in water based industrial wood-, plastic- and metal coatings to increase water, alcohol and block resistance.
-in vinyl coatings to reduce plasticizer migration and improve stain resistance.
-in water based concrete sealers to improve abrasion resistance.
-generally, to improve adhesion of water based systems to non-polar substrates.
-in solvent based polymers to increase resistance properties.
-in water based printing inks to improve water and detergent resistance.
