Technical Information
Terostat-MS 930
Basis: MS ?-Polymer
Issue: 16.06.2004 Product Description
Terostat-MS 930 is a gun-grade, one component sealant based on silane modified polymer, which cures by reaction with moisture to a soft elastic product. The skin formation and curing times are dependent on humidity and temperature, and the curing 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.
Terostat-MS 930 is free of solvents, isocyanates, silicones and PVC, and is odourless. 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.
Terostat-MS 930 allows accelerated curing as 2-component material. See seperate data sheets Terostat-MS Power & Speed Technologie or Terostat-MS 2K-Technologie.
Application Areas
Terostat-MS 930 is used for the following applications:
seam and joint sealing in vehicle body, railway carriage and container manufacture; ship and boat building; metal constructions; the equipment, electrical, plastics, air-conditioning and ventilation industries; for conventional vehicle window glazing between rubber profile and glass (good adhesion to most rubber qualities, even on EPDM -basis), for bonding of floor coverings in bus manufacturing (if required, we will provide you with the necessary information on suitable application equipment).

Application
Preliminary statement
Prior to application it is necessary to read the 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.
Pretreatment
The substrates must be clean, dry, oil and grease free. Depending on the surface it can be necessary to roughen the surface or to use a primer/adhesion promoter to provide optimum adhesion.
When manufacturing of plastics, external release agents are often use d; these agents must be absolutely removed prior to starting bonding or sealing. Due to the different compositions of paints, especially powder paints, and the large number of different substrates, application trials before use are necessary. For cleaning, Cleaner+Diluent A, FL or Terostat-450 from the Teroson programme are suitable.
When bonding and sealing PMMA, e.g. Plexiglass?, and polycarbonate, e.g. Makrolon?or Lexan?, under tension, stress corrosion cracking may occur. Application trials before use are necessary.
There is no adhesion to polyethylene, polypropylene and PTFE (e.g. Teflon?). Substrates not mentioned above should be subject to trials.
Application
Application from 310 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 2–5 bar is required.
Low material temperatures of the sealant will lead to an increase of viscosity, resulting in a lower extrusion rate. This can be avoided by bringing the sealant up to room temperature prior to application. If substrates are too cold temperature may fall below dew point causing condensation. This can be avoided by bringing the substrates up to room temperature in time.
Terostat-MS 930 can also be applied from hobbocks or drums with high pressure pumps with follower plates. See seperate applications directions of Terostat-MS products in hobbocks and drums.
Cleaning
For cleaning application equipment contaminated with uncured Terostat-MS 930 we recommend the use of Cleaner+Diluent A, D or FL.
