SiSiB® silanes are versatile materials used in a wide range of applications including:
Silane Coupling Agent, Silane Adhesion Promoter, Silane Hydrophobing Agent, Silane Dispersing Agent, Silane Crosslinking Agent, Silane Moisture Scavenger, Polypropylene Catalyst "Donor" Silane, Silicate Stabilizer, Polyurethane Endcapper Silane, Silane Drying Agent, Silane Curing Agent, Silane Reinforcer, Silylating Agent, Silane Reducing Agent, Silyl Building Blocks and Synthons etc.
Phenyl functional silanecan improve thermal stability of other silanes.
Phenyl functional silane can be used as other silanes and siloxanes intermediates.
Phenyl functional silane can be used for hydrophobic surface treatment.
Phenyl functional silane can be used as hydrophobic additive to other silane coupling agents.
PC8132 may be used in a variety of applications:
1. Mineral Fillers: as a surface modifier for the aluminum trihydrate (ATH) used as a filler in halogen-free flame-retardant (HFFR) cable insulation
2. Silicones: as a crosslinker in high-temperature silicone elastomers
3. Catalysts: as an electron donor ("A-donor") in the polymerization of polypropylene.
