1 Part RTV Acetoxy

CAF 4 is quick curing, has very good mechanical properties, good heat stability and high dielectric properties.
CAF 4 therefore provides perfect assembly and complete sealing between different materials subject to thermal stresses

CAF 4 is mainly used in industrial sealing, bonding and coating applications:
It is notably used for:

  • bonding of plastics in aeronautics,
  • electrical insulation,
  • coating of fabrics for thermal protection,
  • coating of conveyor belts.
