Main purpose and application

Adhesive 78 BCSP is intended for cold bonding of rubbers (including sponge) with metal (including painted), wood, glass, and other surfaces, as well as rubber-to-rubber bonding.
Adhesive joints using 78 BCSP are resistant to fresh and seawater. Products bonded with this adhesive can operate in all climate zones in the temperature range from -60° to +100°C.

Main application areas:
  • Aviation and shipbuilding: Sealing rubber seals, bonding gaskets to metal surfaces.
  • Automotive industry: Installation of sound insulation, upholstery repair.
  • Construction: Bonding rubber with concrete, wood, glass.
