Coatings

Resins, additives, pigments and functional ingredients for waterborne, solventborne, UV and powder paint systems — sourced direct from verified Chinese manufacturers.

Coatings raw materials span the full formulation stack — from film-forming binders (acrylic emulsions, alkyds, polyurethanes, epoxies) through wet-end additives (dispersants, defoamers, rheology modifiers) to pigments, fillers, and specialty performance additives. The choice of binder chemistry and supporting additives determines almost every end-property of the finished coating: gloss, weatherability, corrosion protection, chemical resistance, through-cure speed, and adhesion to substrate.

Coatingsink supplies the complete raw-materials stack for architectural, automotive, anti-corrosion, marine, wood, can, coil, powder, and UV-curable coating systems. Our portfolio is curated for B2B trade buyers: low MOQs for trial-batch formulation, scaled supply for production, and full COA / MSDS / TDS documentation on every shipment. Each binder, additive, and pigment in our catalog is mapped to its real application area — so you quickly find the grade that matches your formulation.

How to Choose Coatings

Key selection criteria buyers use when specifying coatings for trade and OEM formulations

01

Binder Selection

Acrylic emulsion for exterior weatherability, styrene-acrylic for interior cost balance, polyurethane dispersion (PUD) for chemical resistance, alkyd for traditional brushability and gloss, epoxy for anti-corrosion primers, polyester for coil and powder systems.

02

Pigment & Filler Compatibility

Match TiO2 grade (rutile R902 vs anatase) and dispersion package to your binder system. Carbon black grade impacts jetness, viscosity and rheology. Calcium carbonate, talc, and barytes give cost-effective extension without sacrificing key properties.

03

Rheology Profile

HEUR thickeners give Newtonian flow ideal for spray and roll application. HASE offers shear-thinning behavior preferred for brush. Clay-based or fumed silica for thixotropic high-build pigment-loaded systems. Match rheology to application method, not just final viscosity.

04

Cure Mechanism

Air-drying alkyd or 1K acrylic for low-cost touch-up; 2K polyurethane or 2K epoxy for chemical resistance; UV-cured for fast through-cure on heat-sensitive substrates; stoving alkyd or polyester-melamine for OEM topcoats.

Coatings FAQ

Waterborne coatings use water as the primary carrier — lower VOC, easier handling, but require careful formulation around drying conditions and substrate wetting. Solventborne coatings cure faster, give superior film build per coat, and tolerate poor surface preparation better, but emit higher VOC. The performance gap has narrowed dramatically; most modern architectural and many industrial systems now run waterborne.
