TEROSON MS 939 BLACK - CARTRIDGE 290 ML
Teroson MS 939 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
- Particularly sag-resistant
- High position tack after matching of the parts to be bonded
- Free of solvents, isocyanates, silicones and PVC
- Good adhesion to many substrates
- Compatible with suitable paint systems
- Good UV resistance
- Demonstrates the strength necessary for elastic bonding
- This property of the product also remains at the temperatures in repair ovens (max. 100°C)
Teroson MS 939 allows accelerated curing as two-component material.
Application
Teroson MS 937 is used for the following applications :
- elastic bonding of metals and plastics, e.g. side panelling
- bonding of the roof skin in the vehicle and caravan manufacture
Elastic, interior and/or exterior seam and joint sealing in the following areas:
- vehicle body, caravan, railway carriage, container and general metal construction; the electrical, plastics, air- conditioning and ventilation industries
