- Storage and Handling
At temperatures up to 25 °C storage stability packed in original containers amounts to at least 180 days. Water containing products may freeze at temperatures below 0 °C or become inhomogenous. The product does not suffer any damage from it, the necessary regeneration depends however on a longer warmth treatment at 40 - 50 °C while stirring. Therefore, such products should be stored away from frost.
- Distinguishing Features
Due to the co-crosslinking capability of Additol XW 6591 in melamine and isocyanate systems final coatings show better chemical resistance and salt spray test results compared to any other type of waterborne grinding resin.
- Special Properties and Uses
Additol XW 6591 is a water dilutable grinding medium which can be used for color- and shading pigment pastes. It is compatible with waterborne air-drying and stoving alkyds, waterborne acrylic resins, UV- curing systems, PU- dispersions and plastic dispersions. Additol XW 6591 is co-crosslinking in melamine and isocyanate curing systems.; It offers excellent wetting power for both inorganic and organic pigments.; Especially at high temperature baking conditions ADDITO XW 6591 offers a low level of thermo discoloration.; The pigment pastes are compatible with a wide variety of water dilutable binder systems. Special characteristics of binder systems remain unchanged by the use of Additol XW 6591. Leveling and gloss of coatings can be improved.
