USi-1301 — γ-Aminopropyltrimethoxysilane
Fast-Hydrolyzing Amino Silane for High-Efficiency Coupling, Adhesion & Moisture Resistance
CAS No.: 13822-56-5
EINECS No.: 237-511-5
Molecular Weight: 191.32
Synonyms:- 3-(Trimethoxysilyl)-1-propanamine
✅ Combines a reactive primary amine with three methoxy groups—delivering faster hydrolysis than ethoxy analogs, superior interfacial bonding, and excellent compatibility in water-sensitive systems.
📄 Product Description
USi-1301 features the molecular structure:
H₂N–(CH₂)₃–Si(OCH₃)₃This design offers distinct advantages:
- Primary amine (–NH₂): Reacts efficiently with epoxies, polyurethanes, acrylics, phenolics, and isocyanates
- Three methoxy groups: Hydrolyze faster than ethoxy groups → rapid silanol formation and surface condensation
- Lower molecular weight & higher reactivity: Ideal for applications requiring quick coupling or low-VOC formulations
Widely used to enhance adhesion, mechanical performance, and long-term durability in composites, coatings, adhesives, and foundry binders.

🌟 Key Performance Benefits
⚡ Rapid Hydrolysis & Fast Coupling
- Methoxy groups hydrolyze ~3–5× faster than ethoxy groups → ideal for fast-cure or ambient-cure systems
- Enables quicker development of interfacial strength in composites and adhesives
🔗 Exceptional Adhesion Promotion
- Bonds organic polymers to glass, metals, minerals, and silica-based substrates
- Used as a primer or additive in epoxy, PU, acrylic, and phenolic systems
- Maintains bond integrity under high humidity, thermal cycling, or salt spray exposure
🧱 Enhanced Mechanical Properties
- Significantly improves flexural strength, tensile strength, and modulus in filled composites
- Reduces filler sedimentation in uncured resins → better storage stability and processing consistency
💧 Superior Water & Corrosion Resistance
- Forms a dense, hydrophobic interphase that blocks moisture ingress
- Protects metal substrates from corrosion in primers and coatings
- Extends service life of outdoor and marine applications
🎨 Efficient Filler & Pigment Treatment
- Acts as a coupling agent and dispersant for:
- Silica, calcium carbonate, talc, clay, glass beads
- Improves wetting, reduces viscosity, and prevents agglomeration
🏭 Key Applications
🧵 Glass Fiber Composites
- As a size ingredient or finish on E-glass fibers
- Enhances fiber-matrix adhesion in epoxy, polyester, and vinyl ester composites
- Critical for wind turbine blades, automotive parts, and construction panels
🖌️ Primers for Glass & Metal
- Applied as a pre-treatment layer before coating or bonding
- Creates a chemically active surface for durable adhesion
🧱 Foundry Resins
- Added to cold-curing phenolic and furan resins for:
- Higher green/hot strength
- Improved shakeout and reduced veining defects
- Better humidity resistance during core storage
🧰 Sealants & Adhesives
- Functions as a primer, additive, or reactive modifier in:
- Structural epoxy adhesives
- Silicone-modified sealants
- Polyurethane and acrylic formulations
🛠️ Mineral-Filled Polymers & Composites
- Pretreats fillers for use in:
- Engineering plastics (PA, PBT, PP)
- Thermosets (epoxy, unsaturated polyester)
- Flame-retardant cable compounds
🎨 Paints & Coatings
- Added to water-based or solvent-based systems to:
- Improve adhesion to difficult substrates
- Enhance corrosion protection
- Stabilize pigment dispersion and gloss retention
📦 Packaging
- 25 kg HDPE pail
- 200 kg steel drum
- 950 kg IBC tote
(All containers are nitrogen-purged to minimize moisture exposure and extend shelf life)
🛡️ Safety & Storage
- Flammable liquid – keep away from heat, sparks, and open flame
- Store at ordinary room temperature (≤30°C recommended) in a dry, well-ventilated area
- Shelf Life: 24 months from production date in original unopened containers (for 200L drums)
- Primary amines may absorb CO₂ over time—slight cloudiness may occur but typically does not affect performance
- Use appropriate PPE: nitrile gloves, goggles, and ventilation
- Always consult the latest Safety Data Sheet (SDS)
