polyurethane paint
1.high wear resistance
2.oil resistance
3.good chemical resistance
Detailed introduction to polyurethane paint:
polyester-based polyurethane paint
1, composition:
the paint dry for two-component from the paint, ingredients a hammer for the polyester paste, ingredients for two special curing agent.
2, characteristics and uses:
The product is available through the spray orange peel appearance of the bump pattern film, the film has a good decorative effect, its hardness and high wear resistance and oil resistance, good chemical resistance. Is widely used in machine tools, electrical cabinets and other iron products and plastic products, coating.
3, technical indicators:

Gasoline resistance (5h) is not foaming, non-shedding, a slight discoloration
Note: water resistance, resistance to gasoline of two a week at room temperature in the sample chamber after the test.
4, construction of reference:
1, the paint for the two-component reactive coatings. Shall be in strict accordance with the proportion of paint. Diluted to the construction with special thinner viscosity. As far as possible within 8 hours is used up, so as to avoid wastage.
2, the construction can not be too low viscosity, (Tu -4) 20 seconds or more suitable, or orange peel pattern has not worked.
3, the paint with epoxy primer, polyurethane primer, supporting the use of CPVC primer can also be used alone.
