Additives
Wetting agents, defoamers, dispersants, rheology modifiers, UV absorbers, light stabilizers, and slip additives for waterborne and solventborne formulations.
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.
How to Choose Additives
Key selection criteria buyers use when specifying additives for trade and OEM formulations
Functional Class
Defoamer for entrained air; deaerator for micro-foam release; dispersant for pigment wetting and stability; thickener for rheology; leveler for film smoothness; UV absorber + HALS combination for outdoor durability. Identify the problem before choosing the chemistry.
System Compatibility
Silicone defoamers can craterize sensitive recoat systems — use polysiloxane copolymer where recoatability matters. Polymeric dispersants for inorganic pigments differ from organic pigment dispersants. Always check additive datasheet for binder compatibility statement.
Dosage Window
Most additives have an optimum dose. Below: ineffective. Above: side effects (haze, recoat issues, surface defects). Start at supplier-recommended dose and ladder. Document the dose curve for your specific formulation.
Regulatory / VOC
VOC-exempt additives matter for low-VOC architectural and EU-compliant industrial. APE-free for sensitive applications. Heavy-metal-free for toy safety (EN 71-3). Confirm regulatory profile before formulation lock-in.

Additives FAQ
Mineral oil + silica defoamers (MO400 type) are cost-effective for matt and low-sheen architectural emulsions. For semi-gloss and gloss where surface defects show, polysiloxane copolymer defoamers (DC700 type) give better recoat without craters. Always test recoat at 24h and 48h to confirm.
