Crosslinker XC-113 is a 100% active, polyfunctional aziridine liquid crosslinker. Addition of 1-3% to water based acrylic emulsions urethane dispersions produces a marked improvement in water, chemical, abrasion humidity resistance enhances adhesion to specific substrates. Crosslinker XC-113 is room temperature reactive therefore can be used under air forced drying conditions.

Applications:
In water based parquet lacquers to improve water, alcohol, detergent, chemical abrasion resistance
In water based industrial wood-, plastic- metal coatings to increase water, alcohol block resistance
In vinyl coatings to reduce plasticizer migration 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 detergent resistance.
