The traditional sealant (silicone gel) contains solvents, which can release formaldehyde, VOC (volatile organic compounds) and other harmful to people's physical and mental health. MS sealant does not contain formaldehyde and isocyanate, solvent-free, non-toxic, odorless, VOC release is far below the national standards, is the most environmentally friendly building rubber products.

B. Non-pollution

The traditional silicone sealant will precipitate silicone oil and make it adhere to pollutants. Especially when using porous materials such as stone and concrete, it will cause pollution that is difficult to remove. It is one of the main sources of building facade pollution, which greatly reduces the aesthetic and image value of buildings. MS sealant overcomes such defects in mechanism and will not produce the same pollution.

C. Adhesiveness

Among silicone glue, polyurethane glue and MS sealant, the bonding strength of silicone glue is relatively weak and polyurethane glue is strong, but it needs to be used with primer. MS sealant has excellent bonding performance and can adapt to most building substrates without primer bonding.

D. Weatherability

The molecular structure of MS gum determines its good weatherability. It can maintain good elasticity after long-term exposure to the outdoor environment. The gel itself will not produce bubbles, cracks, and bond strength will last for a long time. It has good thixotropy and extrusion, and can adapt to outdoor, indoor, humid, low temperature and other working environments.
