RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.
Typical Formulation Workflow
1
System & Substrate Assessment
Define the binder system (waterborne, solventborne, UV, powder), substrate, cure, and the VOC, durability, and appearance targets.
2
Additive & Resin Selection
Match resins, pigments and fillers, dispersants, rheology modifiers, defoamers, or biocides to the formulation and compatibility window.
3
Lab Let-Down & Optimization
Dial in loading and addition order through lab let-downs, checking dispersion, rheology, film properties, and storage stability.
4
Application & Performance Testing
Validate on the real application method and substrate, tracking gloss, adhesion, sag, cure, and weathering before scale-up.

Titanium Dioxide
CAS 13463-67-7
무기 충전제 및 안료
Primary white pigment for opacity
Rutile (surface-treated) titanium dioxide reflects and absorbs UV, physically shielding the binder beneath; note uncoated/anatase grades are photocatalytic and promote chalking, so only coated rutile grades protect

Zinc Oxide
CAS 1314-13-2
무기 충전제 및 안료
Active pigment — mildew resistance and UV blocking
3077 (ZINC OXIDE, CRUDE) · Class Genuine inorganic UV absorber/screen used in exterior and clear coatings to block UV-A/UV-B, protecting the binder from photo-oxidation and curbing chalking. Micronized/nano ZnO is used specifically in transparent wood coatings and clear topcoats where pigmentary TiO2's opacity is undesirable, so it is a true complement to the listed TiO2 for this exact UV-weathering/degradation use-case, not just
