Features Of Domestic D-90 Vinyltris(Methylethylketoxime)Silane

  1. Highly effective vinyl-functional silane coupling agent for enhanced polymer–inorganic interface adhesion.

  2. Stable ketoxime-based alkoxy groups ensure extended shelf life and reduced moisture sensitivity during storage and handling.

  3. Low volatility and favorable hydrolysis kinetics enable precise process control in RTV silicone and adhesive formulations.

  4. Compatible with a broad range of fillers, including silica, calcium carbonate, and glass fibers, without premature gelation.

  5. Domestically manufactured under strict ISO 9001-certified quality management, ensuring batch-to-batch consistency and traceability.

Typical Applications Of Domestic D-90 Vinyltris(Methylethylketoxime)Silane

  1. Adhesion promoter in RTV-2 (two-part) silicone elastomers for automotive gasketing and sealing systems.

  2. Surface modifier for mineral-filled thermoplastic composites to improve mechanical strength and dimensional stability.

  3. Coupling agent in high-performance glass fiber-reinforced polyesters and vinyl esters for corrosion-resistant FRP tanks and pipes.

  4. Key additive in moisture-cure polyurethane sealants to enhance substrate bonding on concrete, metal, and coated surfaces.

  5. Functionalization aid in silica-reinforced silicone rubber compounds for improved tear resistance and elongation retention.
