Trimethylolpropane tris(2-methyl-1-aziridinepropionate) Applications

Water-Based Wood Coatings: Trimethylolpropane tris(2-methyl-1-aziridinepropionate) is added to water-based parquet varnishes, furniture coatings and industrial wood finishes to increase water, alcohol, detergent and abrasion resistance. This crosslinker reacts with carboxyl groups in the acrylic or polyurethane binder. A higher crosslink density reduces film swelling when the coating contacts water or cleaning products.

Metal and Plastic Coatings: Used in water-based metal and plastic coatings to improve adhesion, water resistance, chemical resistance and blocking resistance.

Printing Inks and Overprint Varnishes: Trimethylolpropane tris(2-methyl-1-aziridinepropionate) improves wet-rub resistance, wash resistance and adhesion in water-based printing inks and overprint varnishes.

Water-Based Adhesives: Our aziridine crosslinker is used to crosslink carboxyl-functional acrylic and polyurethane adhesives. Crosslinking increases cohesive strength, water resistance, heat resistance and resistance to plasticizer migration.

Leather Finishes: Used in leather topcoats and finishing systems to improve wet-rub resistance, wash resistance, heat resistance and resistance to blocking.

Textile Coatings and Printing Binders: Used in carboxyl-functional textile binders to improve wash durability, wet-rub resistance and adhesion of the printed or coated layer.

Concrete and Floor Sealers: Trimethylolpropane tris(2-methyl-1-aziridinepropionate) can improve abrasion resistance, water resistance and detergent resistance in water-based acrylic floor and concrete sealers.

Packaging and Storage

Packaging: 200KG/drum, or customized packaging according to customer requirements.

Storage: Store in the original tightly closed container in a cool, dry and ventilated area. Keep the product away from acids, oxidizing agents, heat and direct sunlight.
