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 (3)
Vinyl acetate-ethylene (VAE) redispersible polymer
CAS 24937-78-8
Spray-dried VAE copolymer that redisperses in mix water and films on drying, adding flexibility, cohesion and tensile-adhesion bond strength to cementitious mortars

Vinyl acetate-VeoVa redispersible
Vinyl acetate / vinyl-versatate copolymer powder; the branched VeoVa comonomer raises hydrophobicity and alkali/water resistance versus straight VAE for exterior tile adhesive
Polyvinyl alcohol (protective colloid)
CAS 9002-89-5
ポリマー・樹脂
皮膜形成
Water-soluble protective colloid that stabilizes the powder's redispersion and contributes to wet tack and open time
