Description

Thiocyanic Acid, 3-(Triethoxysilyl)Propyl Ester, Reaction Products With Silica is a specialized organosilane-silica hybrid material designed to provide dual functionality as a coupling agent and a reinforcing filler. This product is engineered to enhance the adhesion and compatibility between inorganic substrates and organic polymer matrices, particularly in challenging environments. It is primarily utilized by manufacturers in the rubber, adhesive, and advanced composite industries seeking to improve mechanical properties, chemical resistance, and long-term durability in their formulations.

Application

• As a reinforcing filler and coupling agent in silicone rubber and high-performance elastomers to improve tensile strength and tear resistance.
• To enhance the adhesion and moisture resistance of primers, sealants, and adhesives, especially for bonding to glass, metals, and minerals.
• As a surface modifier for silica in tire tread compounds to reduce rolling resistance and improve wet grip.
• In the formulation of fiber-reinforced plastics (FRP) and composites to promote interfacial bonding between glass fibers and resin systems.
• For the surface treatment of pigments and fillers to improve dispersion and stability in polymer masterbatches.
• In the production of specialty coatings requiring enhanced chemical and abrasion resistance.
