Solutions by Application Area
RTV-1 Silicone Rubber (One-Component Systems)
Used in adhesives and sealants for construction, automotive, and electronics.
- Dynasylan® – Silanes significantly dramatically improve adhesion to substrates like glass, metal, and plastic. They enhance tensile and tear strength, elasticity, and resistance to oils and solvents. Ideal for structural bonding and sealing under dynamic stress and vibration.
- Dynasylan® SIVO – Multifunctional silane systems that enable formulations with reduced VOC content compared with conventional amino silanes, while improving crosslinking efficiency.
- Coupsil® – Pre-treated silicas with silanes for simplified processing and enhanced compatibility in silicone matrices.
- X 50 – AEROSIL®-silica-based processing aid that improves dispersion and handling of fillers, ensuring consistent quality and reduced cycle times.
RTV-2 Silicone Rubber (Two-Component Systems)
Used in encapsulation, potting, and sealing applications across electronics, construction, automotive, and aerospace.
- Dynasylan® – Acts as a crosslinker and adhesion promoter, improving mechanical properties like tensile strength, elasticity, and tear resistance. Enables durable gaskets, seals, and protective coatings that withstand extreme temperatures and pressures.
- AEROSIL® & AEROXIDE® – Fumed silicas and oxides reinforce the silicone matrix, improve flow properties, and enhance thermal and chemical resistance.
