Silicone leveling additive for solvent-based coatings. Tilo-L8221 is a heat resistant silicone additive, i.e., in contrast to conventional (polyether modified) silicones; it shows no thermal decomposition at temperatures between 150°C and 230°C. Thus, upon the recoating baking systems, no loss in adhesion and no surface defects occur. It provides a strong reduction of surface tension of paint systems. Therefore, It especially improves substrate wetting and avoid cratering. Additionally, surface slip and gloss are increased.

The use of thermo-stable silicone additives such as Tilo-L8221 in coil-coatings (or similar systems) can lead to a migration of the silicone to the reverse side of the sheet or roll.
