Base raw materials for coatings formulators and construction chemical manufacturers

RawSource supplies the specialty chemicals that go into architectural coatings, industrial finishes, protective systems, sealants, and construction treatments — not the finished products. We supply silane coupling agents and silicone additives, and source the full range of amine curatives, resins, solvents, fillers, and rheology modifiers through our global network.

Whether you are formulating waterborne architectural paints, high-performance polyaspartic floors, epoxy-amine protective coatings, or silane-based concrete sealers — we supply the raw material inputs your production line needs.

Coatings & Construction Chemistry by Function

Jump straight to the chemistry you need — each guide explains the types, how to select, and routes you to the specific grades we supply.

Defoaming & Air Release
Knock down in-can and application foam without cratering or fisheyes by comparing silicone, mineral-oil and polymeric defoamers for waterborne, solventborne and high-PVC coatings.
Explore →
Rheology & Thickening
Dial in sag resistance, pigment anti-settling and flow/leveling by controlling low- and high-shear viscosity (KU/ICI) with fumed silica and particulate rheology modifiers across paints and industrial coatings.
Explore →
Solvency
Balance solvency, evaporation rate and VOC by matching reducing solvents and coalescing cosolvents (e.g. propylene carbonate, d-limonene) to film formation, viscosity cut and equipment cleanup.
Explore →
Corrosion Control
Protect metal substrates and stop flash rust in waterborne primers by selecting flash-rust inhibitors and anti-corrosive additives for direct-to-metal, primer and protective-coating systems.
Explore →
Light Stabilization
Retain gloss, color and film integrity under sunlight by pairing UV absorbers with HALS to slow photo-degradation in exterior architectural, automotive and coil coatings.
Explore →
UV/EB Curing
Match photoinitiator chemistry to lamp and film thickness (Norrish I vs II) for UV/EB-cured coatings, inks and overprint varnishes, weighing through-cure vs surface-cure and yellowing trade-offs.
Explore →
2K Curing & Crosslinking
Specify hardeners and catalysts for two-component systems: amine and polyamide epoxy curing agents for floor, tank and pipe linings, plus PU catalysts for 2K polyurethane topcoats and their pot-life/cure trade-offs.
