Why It Matters
Coatings delaminate from concrete, steel, and fiberglass on tanks, greenhouse structures, and equipment; need silane coupling agents to chemically bridge the inorganic substrate and the organic coating
Solution Approach
Coatings delaminate from concrete, steel, and fiberglass on tanks, greenhouse structures, and equipment; need silane coupling agents to chemically bridge the inorganic substrate and the organic coating 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 Application Workflow
1
Application & Agronomic Review
Define the use (crop input, adjuvant, soil amendment, post-harvest) and the agronomic, regulatory, and tank-mix requirements.
2
Input & Grade Selection
Match the surfactant or adjuvant, nutrient source, chelate, or formulation aid to the active, water quality, and label.
3
Compatibility & Rate Trial
Confirm tank-mix compatibility, dose, and stability, and size packaging (jugs, drums, totes, bulk) to the season and logistics.
4
Field Validation
Validate efficacy and crop safety in field trials, and lock the spec and supply plan for the season.
Recommended Chemistries (4)
3-aminopropyltriethoxysilane
CAS 919-30-2
Silanes & Organosilanes
Coupling agent
Silanol end hydrolyzes and bonds to siliceous concrete/glass/steel-oxide surfaces while the amine reacts into epoxy/urethane coatings - the covalent bridge that stops delamination
Melting Point: -70 °C Boiling Point: 217 °C Density: 0.94 at 25 °C

3-glycidoxypropyltrimethoxysilane
CAS 2530-83-8
Silanes & Organosilanes
Coupling agent
Glycidoxy group co-reacts with epoxy/amine resins while methoxysilane anchors to the mineral substrate, boosting wet adhesion
Vapor Pressure: 0.002
