W´Pol 1181/03 is a saturated, low viscous polyester resins for the modification of solvent based and aqueous systems showing high elasticity, surface hardness and resistance to chemicals.
Due to its wide compatibility W´Pol 1181/03 can be used in various systems. Normally this polyester resin is used as a modifying component for isocyanate- and amino crosslinking coatings for solvent based as well as for aqueous systems. In corresponding combinations the use of W´Pol 1181/03 improves the flexibility considerably. Often adhesion and gloss are increased at the same time. Very good chemical and mechanical resistance properties are achieved due to the high OH-content which result in a high crosslinking compactness.
In aqueous 2 component PUR systems W´Pol 1181/03 is often combined with polyurethane dispersions which improves the quality considerably even regarding chemical and mechanical resistance.
The recommended addition rate is between 2 - 8% calculated on total formulation.
