Kabasph Additives Solutions for Solvent Thermoplastic Acrylic Systems

Solvent-based thermoplastic acrylic systems are widely used in coatings, inks, adhesives, and aerosol applications where fast drying, good pigment dispersion, excellent gloss, and reliable final performance are essential. However, formulating with these systems presents unique challenges: pigment and filler dispersion stability, viscosity control for high pigment loading, settling and sagging during storage and application, insufficient substrate wetting—especially on oily or contaminated 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 thermoplastic acrylic chemistry without adversely affecting drying speed, storage stability, gloss, transparency, recoatability, or final film properties.
