Brief introduction
062 is waterborne polyurethane dispersion with functions of self-crosslinkingfast drying at room temperature. It was synthesized with water as dispersion medium, adopted advanced formula design ideasproduction process. Water-based coating film formulated by this resin has excellent performances such as high fullness, good flexibilityelasticity, good non-yellowing, good glossabrasion resistance, Eco-friendly, non-toxic as well as harmless to human body.
Features:
1. Softelastic, high gloss, good fullness, excellent water resistanceabrasion resistance
2. Fast drying
3. Elongation exceeds 500%
4. Good adhesion to plastics, leatherother flexible materials
5. No free isocynate monomer, no benzene substance, formaldehydeother toxic solvent, water-based, Eco-friendlynon-toxic.
Applications:
1. Water-based printing inks
2. Finishing varnish
3. Water-based shoe coatings
4. Can be used on a wide range of substrates such as textile, paper, plastic, leather, rubber, etc.
Application guidelines:
1. Good compatibility with non-ionicanionic water-dispersible polyester resin, water-dispersible alkyd resins, acrylic emulsionswater dispersible PU curing agent;
2. Can be adjusted to the desired viscosity by thickening agent
3. It is non-yellowing, can be used for light color substrates.
4. Painting methods: spraying, curtain coating, dip coating;
5. Curing conditions: room temperaturelow temperature baking
