ソリューションアプローチ

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.
