WebMost water-based paint formulations still need up to 10% solvent to make the polymer form a homogeneous film. The coat is cured at temperatures ranging from 20°C to 80°C. To ensure adequate polymer network formation, an excess of isocyanate is added to compensate for the isocyanate consumed during the urea reaction. WebMar 21, 2014 · Generally, paints are composed of a binder, a solvent, and a pigment. The binder is a polymer, either dissolved in the paint or suspended in it by emulsifiers, the role of which is to hold the pigment to the surface. For emulsion paints, the solvent used is just water, whilst for others organic compounds such as turpentine are utilised.
