Why It Matters
Durable bonding of rubber to steel, aluminum, and other metals using silane primers/adhesion promoters that bridge the metal oxide and the rubber
Solution Approach
Durable bonding of rubber to steel, aluminum, and other metals using silane primers/adhesion promoters that bridge the metal oxide and the rubber 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 (3)
Mercaptopropyltrimethoxysilane (MPTMS)
CAS 4420-74-0
Silanes & Organosilanes
Mercapto silane for rubber
Methoxysilane end bonds the metal oxide surface while the thiol couples into the sulfur-cured rubber, forming a covalent metal-to-rubber bridge that resists peel (slug corrected: a mercapto silane, not an amino silane)

3-aminopropyltriethoxysilane (APTES)
CAS 919-30-2
Silanes & Organosilanes
Primary amino silane
Aminosilane primer that anchors to metal hydroxides and presents an amine to react with the rubber/adhesive layer
Melting Point: -70 °C Boiling Point: 217 °C Density: 0.94 at 25 °C

Bis-(3-triethoxysilylpropyl)-tetrasulfide (Si-69 / TESPT)
CAS 40372-72-3
Silicone Fluids & Oils
Tetrasulfide silane for tires
Sulfur-functional silane usable as a rubber-side adhesion promoter, bonding to metal-oxide-primed surfaces and into the vulcanizate
