Cationic and Nonionic Waterborne Polyurethanes
Cationic waterborne polyurethanes were mainly used in fabric processing, leather primer, metal surface treatment, glass fiber infiltration agent and wood surface treatment, etc.
Nonionic waterborne polyurethanes have good compatibility with cationic and anionic waterborne polyurethanes, acrylic emulsions, or other ionic aqueous resin. They also display good compatibility with silanes, adhesion promoters, slip agents, antistatic agents and flexibilizers.
The following are a few of our most common cationic and nonionic waterborne polyurethane products:
Cationic, aqueous aliphatic polyurethane dispersion based on polyether. The film is soft, mainly used in fabric processing and leather primer.
Cationic, aqueous aliphatic polyurethane dispersion based on polycarbonate. The coating has high hardness, excellent abrasion resistance, heat resistance, excellent water resistance and resistance to salt spray. Mainly used for metal surface treatment, fiberglass infiltration agent, wood surface treatment etc.
Nonionic, aqueous aliphatic polyurethane dispersion based on polyester. Its film is soft and elastic. It has good compatibility with cationic and anionic aqueous polyurethane dispersions, acrylic emulsions, or other ionic aqueous resin.
