Polyurethane Finish Coating
The polyurethane finish coating is a paint film containing a number of polyurethane links. In addition, there are urea links, ether links, ester bonds, allophanate links, etc. in the finish coating. Conventionally, it is still named as polyurethane paint.
As a commonly seen paint, the polyurethane finish coating falls into single component and two component finish paint. The two component polyurethane finish coating is composed of isocyanate prepolymer and hydroxyl-containing resin, or normally known as firming agent and base. There are many types of the polyurethane finish coating, including acrylic polyurethane, alkyd polyurethane, polyester urethane, polyether-urethane, and epoxy polyurethane coating. With excellent mechanical properties and solid content, the polyurethane paint has wide applications and great potential.
The polyurethane finish coating can be applied through spray coating, brush painting, and roller coating, which have varied requirement for viscosity of coatings. Viscosity regulation should be achieved by means of special thinner, with water, banana oil, alcohol, and gasoline strictly prohibited.
