Reactive thiol (–SH) group enables covalent bonding with metals, sulfur-cured elastomers, and radiation-curable systems.
Three hydrolysable methoxy groups provide strong siloxane network formation and durable adhesion to glass, silica, and metal oxides.
Gamma-positioned mercapto functionality ensures optimal balance between reactivity and hydrolytic stability.
Low volatility and high purity support consistent performance in precision applications such as adhesives and sealants.
Functionally bridges organic polymers and inorganic substrates—enhancing interfacial strength and moisture resistance.
Tire and rubber compounds—improves silica-reinforced tread adhesion and reduces rolling resistance.
Adhesives and sealants—boosts bond durability on metals, glass, and coated substrates.
Radiation-curable coatings and inks—acts as a thiol-ene crosslinker for rapid, low-shrinkage curing.
Composite materials—enhances fiber-matrix interfacial adhesion in glass- and carbon-fiber reinforced thermosets.
Surface modification of fillers and pigments—improves dispersion and compatibility in polymer matrices.
