Why It Matters
Mineral-filled thermoplastics/thermosets suffer poor filler-polymer bonding, low mechanical strength, and moisture-driven debonding; silane coupling agents bridge the inorganic filler and organic matrix
Solution Approach
Mineral-filled thermoplastics/thermosets suffer poor filler-polymer bonding, low mechanical strength, and moisture-driven debonding; silane coupling agents bridge the inorganic filler and organic matrix 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.

3-aminopropyltriethoxysilane (APTES)
CAS 919-30-2
Silanes & Organosilanes
Primary amino silane
Triethoxy end hydrolyzes to silanols that condense onto mineral-filler hydroxyls while the pendant primary amine reacts with the polymer, forming a covalent filler-to-matrix bridge
Melting Point: -70 °C Boiling Point: 217 °C Density: 0.94 at 25 °C

3-aminopropyltrimethoxysilane (APTMS)
CAS 13822-56-5
Silanes & Organosilanes
Methoxy amino silane
Methoxy version hydrolyzes faster than ethoxy for quicker filler surface anchoring; the amine couples to acidic/anhydride-functional polymers
Physical Description: Clear to straw-colored liquid with an ammoniaca…

3-(2-Aminoethylamino)propyltrimethoxysilane (diamine silane)
CAS 1760-24-3
Silanes & Organosilanes
Enhanced adhesion
Two amine groups give higher reactive-site density at the interface, raising bond durability under moisture for filled compounds
Physical Description: Light yellow liquid Vapor Pressure: 0.03
