Approche de solution
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 Formulation Workflow
1
System & Substrate Assessment
Define the binder system (waterborne, solventborne, UV, powder), substrate, cure, and the VOC, durability, and appearance targets.
2
Additive & Resin Selection
Match resins, pigments and fillers, dispersants, rheology modifiers, defoamers, or biocides to the formulation and compatibility window.
3
Lab Let-Down & Optimization
Dial in loading and addition order through lab let-downs, checking dispersion, rheology, film properties, and storage stability.
4
Application & Performance Testing
Validate on the real application method and substrate, tracking gloss, adhesion, sag, cure, and weathering before scale-up.

3-aminopropyltrimethoxysilane
CAS 13822-56-5
Silanes et Organosilanes
Methoxy analog — faster hydrolysis
CAS correct for APTMS. Primary aminosilane adhesion promoter — the workhorse for wet-adhesion to mineral/metal substrates in moisture-cure RTV/hybrid sealants; trimethoxy groups co-condense into the curing network. Genuine fit.

Vinyltriméthoxysilane
CAS 2768-02-7
Silanes et Organosilanes
Vinyl silane for polyethylene crosslinking
CAS correct for VTMO. Classic water-scavenger/drying agent (and alkoxy-cure crosslinker) in one-part moisture-cure PU/MS/silicone systems, consuming trace can moisture to prevent premature gel. Genuine fit.
Point de fusion:ˆ'97°C Point d'ébullition:123°C at 1013 hPa (converted to 101.3 kPa) (760… Densité:Specific Density: 0.94 (water = 1)

3-(2-Aminoethylamino)propyltrimethoxysilane
CAS 1760-24-3
Silanes et Organosilanes
Diamine silane for enhanced adhesion
CAS correct for AEAPTMS (diaminosilane, A-1120/DAMO class). The most common sealant adhesion promoter; stronger durable bonding on masonry/glass than the mono-amine, trimethoxy grafts into the elastomer. Genuine fit.
Physical Description: Light yellow liquid Vapor Pressure: 0.03

3-glycidoxypropyltriethoxysilane
CAS 2602-34-8
Silanes et Organosilanes
Ethoxy analog — slower hydrolysis, better storage
PubChem confirms CAS 2602-34-8 = triethoxy-[3-(oxiran-2-ylmethoxy)propyl]silane (C12H26O5Si). Epoxy-functional, non-amine/non-yellowing adhesion promoter for SMP/hybrid moisture-cure sealants; ethoxy groups condense into the cure. Genuine fit (ethoxy-cure niche vs the common trimethoxy A-187, but real).
Physical Description: Liquide

3-glycidoxypropyl methyldiethoxy silane
CAS 2897-60-1
Monoalkyl epoxy silane for flexible crosslinks
PubChem confirms CAS 2897-60-1 = diethoxy-methyl-[3-(oxiran-2-ylmethoxy)propyl]silane (C11H24O4Si). Difunctional epoxysilane adhesion promoter; the single methyl caps one hydrolyzable site to limit added crosslink density, keeping cured modulus/elongation in spec. Genuine fit.
