Teroson MS 931 WH -290 ml (adhesive and sealing mass, white)/Terostat MS 931

Product description:
Teroson MS 931 is a one-component sealant based on silanemodified polymer, which can be applied by pouring and extruding. The material cures by reaction with moisture to a soft elastic product. The skin formation and curing times are dependent on humidity andtemperature, 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. Teroson MS 931 is free of solvents, isocyanates, silicones and PVC, and is odorless. The sealant also demonstrates good UV resistance and can therefore be used for interior and exterior applications. Teroson MS 931 allows accelerated curing as two-component material. Further information on the product can be obtained from your local technical department:

Steps to achieve the best adhesive results:
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 best adhesion. When manufacturing plastics, external release agents are often used; these agents must be accurately 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 EROSON VR 30, TEROSON VR 10 or TEROSON SB 450 from the Henkel portfolio are suitable. . When bonding and sealing PMMA, e.g. Plexiglas®, 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. Substrates not mentioned above should be subject to trials.

Application from 290 ml cartridges is made with the Hand or 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. This can be avoided by bringing the sealant up to room temperature prior to application. Teroson MS 931 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.

For cleaning application equipment contaminated with uncured Teroson MS 931 we recommend the use of Cleaner+Diluent Teroson A, D or FL.
