Additives are the small-percentage ingredients that solve the formulation problems binders and pigments alone can't. A 0.2% defoamer cures a foam-out batch; 0.5% silicone leveler converts a craterous coating to glass-smooth; 1.5% HEUR thickener gives the architectural paint its can-stable, brush-friendly rheology. The compounded effect of additive selection is enormous — many coating performance differences between manufacturers come down to additive choices, not binder or pigment.

Coatingsink supplies the full additive toolkit for trade formulators: silicone and acrylic levelers (BYK-equivalent grades), polysiloxane defoamers for waterborne and solvent, polymeric dispersants (Disperbyk-equivalent and Tego-equivalent), HEUR and HASE thickeners, UV absorbers (Tinuvin 326/328) and HALS (Tinuvin 152, 622-oligomeric), wax dispersions for matting and slip, plus specialty additives for adhesion promotion, anti-corrosion, and surface modification.
