Casilane Silanes – Industrial Specialities
Technical Expertise. Smarter prices.
High-performance silane coupling agents that enhance filler dispersion and adhesion in composites, delivering improved strength, durability, and processing efficiency across tyres, rubber, plastics, and coatings. Casilane™ is Thomas Swan’s range of organofunctional silanes that form a chemical bridge between inorganic fillers (silica, glass, minerals, metal oxides) and organic systems (polymers, coatings, adhesives, sealants). This improved interface gives cleaner dispersion, better mechanical properties, and more reliable processing.
Casilane™ products are supported by our technical team to help you select the right solution for your formulation, and are offered at competitive pricing thanks to efficient sourcing and production.
Proven performance
Engineered for broad use across plastics, composites, coatings, adhesives and sealants where adhesion, mechanical strength, moisture resistance and durability are critical.
Processing efficiency
Improved filler wetting and dispersion can reduce mixing energy, give more uniform compounds, and minimise defects.
Cost-efficient solutions
Premium silane performance at competitive pricing, enabled by efficient sourcing and production.
Technical expertise
Direct access to our silane specialists to match the right chemistry to your polymer/filler system and end-use conditions.
