W´Add 486 is a special polyester resin to improve the adhesion of solvent-based air drying, stoving and 2 component PUR-systems.
The addition of W´Add 486 improves clearly the adhesion on different substrates, for example metals, melamine resin coated chipboards, etc. Also the elasticity of paint systems can be improved by W´Add 486.
To improve adhesion W´Add 486 is stirred into the paint during production or afterwards added to the finished product. The usual dosage is between 1 - 3% calculated on the total formulation. To optimize the dosage, a serial investigation is recommended. W´Add 486 is heat resistant up to 180 °C
