Finishing — Process Challenge

Polyurethane Coatings & Silane Promoters for Textiles

Coated and laminated textiles need a film-forming polymer, the right solvent system, fillers and good adhesion
Why It Matters
Coated and laminated textiles need a film-forming polymer, the right solvent system, fillers and good adhesion
Solution Approach

Coated and laminated textiles need a film-forming polymer, the right solvent system, fillers and good adhesion 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 Processing Workflow
1
Substrate & Process Assessment
Identify the fiber and process stage (pretreatment, dyeing, finishing) and the performance, hand, and compliance targets.
2
Auxiliary Selection
Match surfactants, wetting and dispersing agents, softeners, fixatives, or pH and sequestering agents to the substrate and bath chemistry.
3
Lab Dip & Dosing
Confirm dose and sequence on a lab dip or pad trial, checking levelness, fastness, hand, and bath stability.
4
Production Validation
Verify reproducibility, fastness, and effluent compliance at scale, and set the recipe and packaging for production.
