Premium 3-Aminopropyltrimethoxysilane (APTMS/KH-540) – High-Performance Coupling Agent

Ultra-Pure Formula
– Precision-engineered with 99% purity (CAS No. 13822-56-5) for unmatched adhesion and stability in demanding industrial applications.
Advanced Surface Modification
– Enhances bonding between organic polymers and inorganic materials like glass, metals, and ceramics for durable composites.
Multi-Industry Versatility
– Ideal for adhesives, coatings, electronics (PCB encapsulation), and nanomaterial synthesis (silica nanoparticle functionalization).
Controlled Hydrolysis
– Methoxy groups ensure optimal reactivity with moisture-sensitive substrates, enabling uniform film formation.
Bulk Supply Advantage
– Direct manufacturer sourcing guarantees the lowest global pricing for wholesale quantities (tons available).
Strict QC Standards
– Batch-tested for consistent viscosity (20-25 cP at 25°C) and low chloride content (<50 ppm).
Global Logistics Network
– Fast shipping with flexible packaging (1kg to 25kg drums) to labs and factories worldwide.
