Borchi®Gel additives are associative and non-associative rheology additives used in water-based coatings. They have a significant impact on the storage stability and application performance of the coating system. Advantages include a full range of low to high shear polyurethane type, acrylic type and zirconium complex type thickeners to ensure optimal flow and leveling as well as anti-sag properties. |
