Solution Approach
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.
Recommended Chemistries (4)
UV-328 Benzotriazole UV Absorber (Tinuvin 328 Type)
CAS 25973-55-1
Specialty Additives
Organic UV absorber for clear coatings
Hydroxyphenyl-benzotriazole UVA absorbs 300-380 nm light and dissipates it as heat, protecting resin and substrate from photolysis
Physical Description: Dry Powder, Pellets or Large Crystals; NKRA; Ot… Appearance: White to yellow powder or crystals Solubility: In water, log -1.37

BHT (Butylated Hydroxytoluene), Food Grade
CAS 128-37-0
Specialty Additives
Antioxidant for resin stabilization
Hindered-phenol antioxidant donates H to chain-carrying peroxy radicals, interrupting thermal/photo-oxidative degradation of the resin
Melting Point: 69–71 °C Boiling Point: 265 °C at 760 mmHg Density: 1.048 at 20 °C

Titanium Dioxide
CAS 13463-67-7
Mineral Fillers & Pigments
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
Melting Point: 1860 °C (decomposes) Boiling Point: 2500–3000 °C at 760 mmHg Density: 3.9 to 4.2
