Waterborne Polyurethane paint
The special imported water-based trapezium, the national chemical science, deionized water, water-based additives and environmental protection filler and other components, does not contain benzene, a family, second-grade benzene and other organic solvents.The product is prepared by using water-based aliphatic polyurethane resin as film forming base material, HDI as curing agent, adding environmentally friendly fillers and functional auxiliars. Full film, high gloss, bright color. Good adhesion, high hardness, excellent weather resistance.
Application field
Suitable for high surface requirements, high weather resistance requirements of the top paint coating. It is mainly used in the surface decoration of metal components such as wind power tower barrel, mechanical equipment, construction machinery, petrochemical oil pipe, etc. It has very excellent outdoor weather resistance and corrosion resistance.
Surface treatment
1. The surface must be clean and dry, and the surface treatment of the substrate must meet the requirements.
2. The tools used in the construction must be dry and clean. 3.
3. it is forbidden to contact with acid and alkali during the process of paint preparation and coating.
4. the painting interval must be strictly controlled, when the temperature is 25′C, the painting interval shall not be less than 12 hours.
5. Can not paint thick, a film can not exceed 40μm or will bubble.
6. Construction and drying and curing during the relative humidity is not greater than 75%, the temperature can not be less than 0 ℃ C, otherwise the film can not be completely cured influence.
