Ms (modified silicon) Adhesive Sealant for Solar PV Industry (Flexibond 8510)
Flexibond MS 8510 provides the following product characteristics:
Technology Silane modified polymer
Product Type Sealant
Appearance White, Grey, Black
Consistency Pasty, Thixotrpic
Flexibond MS 8510 is a sag resistant one component adhesive based on silane modified polymer, which cures by reaction with moisture to an elastic product. The skin formation and the 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. Flexibond MS 8938 is free of solvents, isocyanates, silicones and PVC. It demonstrates good adhesion to many substrates. The sealant also demonstrates good UV resistance and can therefore be used for interior and enterior applications. Flexibond MS 8510 allows accelerated curing as two-component material. See Flexibond MS 8510 2c Technology Date Sheet.
Flexibond MS 8510 is used for elastic bonding on metallic or painted substrates as well as for adhesive sealings of all kind. It is particularly suitable for applications where after matching of the materials to be bonded a high position tack is needed.

DIRECTIONS OF USE
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. Corona or Plasma treatment improves the adhesion to many different materials. 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. 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 (e. G.
Teflon® ). Substrates not mentioned above should be subject to trials.
Application from 310ml cartridgrs 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 avioded 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. Contact us if you need more details on Ms Polymer.
