Kabasph Additive Solutions for Solvent High-temperature Baking Paint Systems

Solvent-based high-temperature baking paint systems are widely used in coatings and industrial finishes where thermal curing, high gloss, excellent durability, chemical resistance, and reliable final performance are essential. However, formulating with these systems presents unique challenges: pigment and filler dispersion stability at elevated temperatures, viscosity control for high pigment loading, settling and sagging during storage and application, insufficient substrate wetting—especially on oily or contaminated metal surfaces—surface defects such as craters, orange peel, floating and flooding, foam generation that compromises film quality, and adhesion failure on metal and non-metal substrates. Additives must be carefully selected to maintain compatibility with the baking paint chemistry without adversely affecting curing speed, storage stability, gloss, transparency, recoatability, salt spray resistance, or final film properties.
