Application
Sealants and Adhesives
Acts as a bonding promoter for polysulfide, polyurethane, epoxy, and acrylic sealants/adhesives, significantly enhancing adhesion and water resistance on substrates such as glass, metal, and concrete.
Functions as a crosslinking agent in water-based resin systems (e.g., acrylic and polyurethane coatings), extending shelf life while improving coating properties like wear resistance, scrub resistance, and waterproofing.
Electronic Materials and Encapsulation
Used in epoxy-based electronic materials, potting compounds, and printed circuit boards (PCBs) to enhance electrical performance under humid conditions and improve resin-substrate adhesion.
Strengthens mechanical properties, heat resistance, and weather resistance in electronic component sealants.
Coatings and Surface Treatment
Applied in fiberglass-reinforced plastics (FRP), anti-corrosion coatings, and high-temperature-resistant coatings to boost chemical stability and weather resistance.
Serves as a surface treatment agent for inorganic fillers (e.g., silica powder, white carbon black, metal powders), improving compatibility and dispersion with resins.
Industrial Composites
Used as a sand mold binder in precision casting or for waterproof/anti-corrosion treatments on metal surfaces.
Forms a "molecular bridge" between resins and inorganic materials via silanol group reactions, enhancing interfacial bonding strength in composites
