Teroson MS 935 is a gun-grade, one-component sealant based on silane modified polymers, which cures by reaction with moisture to an elastic product.
Characteristics
- The skin formation and curing times are dependent on humidity and temperature
- By increasing the temperature and moisture these times can be reduced
- Free of solvents, isocyanates, silicones and PVC
- Demonstrates the strength necessary for elastic bonding
- High viscous and sag resistant
- Compatible with suitable paint systems
- Good UV resistance
Teroson MS 935 allows accelerated curing as two-component material.
Application
Teroson MS 935 is used for the following applications :
- elastic, anti-flutter bonding of metals and plastics (panel stiffeners, roof skins etc)
- elastic, bonding of wood core plywood to the metal boat deck in ship building industry
Elastic, interior and/or exterior seam and joint sealing in the following areas :
- vehicle body, railway carriage, container and general metal construction
- the equipment, electrical, plastics, airconditioning and ventilation industries
