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. Typical properties Type polyfunctional aziridine crosslinker Appearance clear yellowish liquid Total solids (w/w %) >99 Viscosity Brookfield (25℃) 200mPa.s PH (25℃) 8-9 Density (20℃) 1.08kg/l Stability (20℃) 6 months Water tolerance (%) >100 Solubility complete in acetone, xylene, isopropanol n-butyl acetate, carbitol, butyl carbitol 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.
