Water-based, ready-to-use hydrolysate—no on-site acid catalysis or aging required.
Contains reactive aminoalkyl-functional silane oligomers for strong covalent bonding to inorganic substrates and organic polymers.
Low volatility and non-hazardous formulation—exempt from VOC reporting under major regulatory frameworks (e.g., EU REACH, US EPA).
Excellent hydrolytic stability in neutral to mildly acidic aqueous systems (pH 4–6.5).
Enables uniform surface functionalization of silica, glass, metals, and mineral fillers without precipitation or gelation.
Surface treatment of silica fume and precipitated silica in high-performance rubber compounds (e.g., tire treads).
Adhesion promotion in waterborne coatings for metal and concrete substrates.
Functionalization of glass fibers for improved matrix compatibility in thermoset composites (epoxy, phenolic).
Stabilizer and coupling agent in aqueous mineral pigment dispersions for architectural and industrial paints.
Pre-treatment for aluminum and galvanized steel prior to cathodic electrocoating (e-coat) in automotive OEM lines.
