Product description:
Teroson MS 939 FR is a gun-grade, one component sealant/adhesive based on silane modified polymer, which cures by reaction with moisture to an elastic product. The skin formation and curing times are dependent on humidity and temperature, and thecuring time also depends on joint depth. By increasing the temperature and moisture these times can be reduced. Low temperature as well as low moisture retard the process. Teroson MS 939 FR is free of solvents, isocyanates, silicones and PVC. It demonstrates good adhesion to many substrates and is compatible with suitable paint systems. The sealant also demonstrates good UV resistance and can therefore be used for interior and exterior applications. Teroson MS 939 FR demonstrates the strength necessary for elastic bonding. Teroson MS 939 FR is a flame retardant sealant and is therefore used for applications where reduced inflammability and low combustibility is needed, for example in vehicle construction.

Directions for use:
1. Prior to application it is necessary to read the material safety data sheet for information about precautionary measures and safety recommendations. Also, for chemical products exempt from compulsory labeling, the relevant precautions should always be observed.
2. Application from 290 ml cartridges is made with the Teroson Hand or Air Pressure Pistols, and from plastic wallets (310 and 570 ml) with the corresponding FK-Hand or FK-Air Pressure Pistols. In the case of compressed air application a pressure of 2 to 5 bar is required. Low material temperatures of the sealant will lead to an increase of viscosity, resulting in a lower extrusion rate.
3. This can be avoided by bringing the sealant up to room temperature prior to application. Teroson MS 939 FR can also be applied from hobbocks or drums with high pressure pumps with follower plates. See separate application directions of Teroson MS products in hobbocks and drums.
