Why It Matters
Roof-coating formulators source acrylic/styrene-acrylic emulsion, TiO2, associative thickener and biocide for reflective elastomeric membranes. The binder + pigment + rheology stack is largely in catalog, with a roof-grade elastomeric emulsion as the one sourcing flag
Solution Approach
Roof-coating formulators source acrylic/styrene-acrylic emulsion, TiO2, associative thickener and biocide for reflective elastomeric membranes. The binder + pigment + rheology stack is largely in catalog, with a roof-grade elastomeric emulsion as the one sourcing flag 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.
