Special Properties and Uses
  • Additol XL 6577 is a low molecular weight additive, which is especially able to deflocculate and stabilize inorganic pigments very actively by electrical charging at the pigment surface and permits very low viscosity millbase formulations.
  • Due to the high wetting power of Additol XL 6577, coatings/inks with high gloss and improved color strength can be achieved. It decreases settling of pigments/extenders and offers good leveling. In consequence of its acidic character Additol XL 6577 is also recommended for the use in metallic formulations since it shows very good stabilization of aluminum flakes. It is also qualified for the production of highly concentrated inorganic pigment pastes and matting agent pastes.
  • Additol XL 6577 should be added in the grinding step. Quantity to be added: 0.25 - 2.5 % on pigment / extender and matting agent

Storage & Handling

Storage and Handling

At temperatures up to 25 °C storage stability packed in original containers amounts to at least 365 days. Upon long term exposure to temperatures below 10 °C, Additol XL 6577 may get cloudy and may show some crystallization. These effects are reversible and can be eliminated by warming up the product to 30 - 40 °C for several hours. After this treatment the product can be used without any restrictions.
