Why are BRB Silanil Silanes gaining industry attention?
27 March 2026

As highlighted in the recent Surface Coatings International – Journal of the Oil & Colour Chemists’ Association – feature “The Diverse Applications of Silanes”, silanes play a critical role as adhesion promoters, coupling agents, surface modifiers, hydrophobisation agents, and crosslinkers across a remarkable range of industries.
The BRB Silanil® range offers tailored functionalities — amino, epoxy, vinyl, methacryloxy, mercapto, and alkoxy silanes — enabling formulators to solve challenges in:

  • Paints & Coatings: Improved adhesion, weatherability, and corrosion resistance
  • Sealants & Adhesives: Superior bonding to glass, metals, minerals, and composites
  • Plastics & Rubber: Enhanced filler coupling and mechanical strength
  • Construction Materials: Deep penetrating water repellency, chloride protection & long-term durability
  • Wire & Cable: High-performance XLPE crosslinking and insulation stability
  • Composites & Glass Fibre: Stronger matrix bonding & moisture resistance

One standout is BRB Silanil® 299, a phenyl-functional trimethoxysilane offering exceptional thermal stability, hydrophobicity, and even high refractive index value for advanced optical and electronic applications.

BRB’s strategic collaboration with Tennants Distribution ensures UK manufacturers benefit from strong technical support, reliable supply, and deep market expertise — making it easier than ever to integrate Silanil® technologies into modern, high-performance formulations.
