Product Dexcription MS3931 is a modified silane polymer based one parts and moisture cured elastic sealant. The temperature impacts on the curing speed and skinning. Higher temperature and more moisture will reduce the time to skin and accelerate the curing speed, vice versa. The application thickness of the sealant will impact on the curing speed. It does not contain any solvent, isocyanate, PVC or silicone. It does not emit harmful VOC when it cures. It can be applied outdoor and indoor with the excellent property of UV resistant and anti-aging.
Chemical Content: MS Sealant Appearance: Paste Color: Black, Grey, White and others Curing: Moisture Cured Odor: None
Application: Self-leveling joint sealing: welding joint sealing; all the application for seam sealing, sandwich panel bonding and elastic coating. It has strong adhesion to rubber and EPDM.
Application: 1. The substrates must be sound clean and free of dust, grease, stain and any loose sontainment; 2. For some substrates, must be pre-treated with primer, such as pine tree timber; 3. Physical method can be applied to remove the rust on the substrates; 4. We strong recommend to the test pre-application, due to the uncertainty for wide range of substrates; 5. Paints can be applied on the surface of the sealant after it is tack free;computability should be tested; 6. When application under low temperature, heat up the sealant (below 70ºC) will be helpful to extrude.
