In depth interpretation of the application value of crosslinking agents in coatings

Crosslinking agent is a water dispersed and blocked isocyanate crosslinking agent, which can be used as a single component crosslinking agent for water-based coatings and water-based adhesives. It can also be applied to solvent based systems. This crosslinking agent has many characteristics, such as high tension, high activity, and can react with carboxyl and hydroxyl groups at room temperature to form an independent network structure for crosslinking purposes. This cyclic structure reacts very quickly in water-based coatings and has a significant effect. It has good crosslinking and curing properties in products made from polymers such as polyacrylic acid esters, polyethylene, polyurethane, polystyrene, proteins, and polysaccharides.

The product is used for shoe material glue, as a long-lasting curing agent for vulcanized shoe glue, and is non adhesive; The baking temperature is low and the time is short. Applied to water-based coatings such as acrylic acid and polyurethane, as an adhesion promoter and crosslinking agent. Improve the adhesion strength, waterproofing, wear resistance, scrub resistance, scratch resistance, and chemical resistance of the coating. It can be added to polymer systems such as acrylic esters, polyesters, epoxy resins, and polyurethane resins to enhance the chemical and weather resistance of coatings. Can be applied to baking paint, coil steel paint, and corrosion-resistant paint, etc. Especially suitable for coating in automotive factory paint, it can improve flexibility, impact resistance, and adhesion; It can also be used as an additive to improve the mechanical properties and stone impact resistance of traditional baking coatings.
