Why It Matters
Latex paints must hold a target alkaline pH for colloidal/thickener stability and in-can shelf life; amine neutralizers and buffers offset drift
Solution Approach
Latex paints must hold a target alkaline pH for colloidal/thickener stability and in-can shelf life; amine neutralizers and buffers offset drift 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.
