Why It Matters
Improving filler dispersion, lowering viscosity, and raising mechanicals in filled thermosets via silane and titanate coupling agents
Solution Approach
Improving filler dispersion, lowering viscosity, and raising mechanicals in filled thermosets via silane and titanate coupling agents 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 Treatment Workflow
1
System Assessment
Characterize operating conditions—fluid composition, temperature, pressure, flow rates—and benchmark current treatment performance.
2
Chemistry Selection
Match base chemicals to your operating envelope. Factor in compatibility with existing programs, regulatory constraints, and downstream impacts.
3
Dosage & Delivery
Determine optimal treat rates through jar testing or field trials. Configure packaging (drums, totes, ISO tanks) to match consumption and storage logistics.
4
Monitoring & Adjustment
Track KPIs—coupon rates, residuals, separator performance, water quality. Adjust chemistry and dosage as conditions change.
Recommended Chemistries (4)
3-glycidoxypropyltrimethoxysilane (GPTMS)
CAS 2530-83-8
Silanes & Organosilanes
Primary epoxy silane
Epoxy silane couples mineral filler to epoxy/anhydride thermoset; the glycidoxy group reacts into the resin network while silanols bond the filler, raising strength and cutting viscosity
Vapor Pressure: 0.002
