SiSiB® PC4600 is a versatile coupling agent that can be used in many applications utilizing a free-radical cure mechanism. The silane is used in fiber-optic coatings, acrylic coatings, artificial marble, adhesives & sealants, and thermoplastics.

It can improve mechanical and electrical property retention better than the more common methacryl silane SiSiB® PC4100.

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.
