MS plastic encyclopedia

MS glue is also called silane modified polyether sealant. Due to its non-formaldehyde and isocyanate-free properties, it has outstanding environmental characteristics such as solvent-free, non-toxic and tasteless, low VOC emission and is environmentally friendly and human-friendly. It adapts to most construction substrates and has good workability and adhesion , Durability and weatherability, especially with non-polluting and paintable, has a wide range of applications in architectural decoration.

Compared with the mainstream architectural sealants on the market, MS glue has the following characteristics:

1) Health and environmental protection

Traditional sealant (silicone gum) due to containing solvents, will release formaldehyde, VOC (volatile organic compounds) and other human and physical harm to human health. MS glue does not contain formaldehyde and isocyanate, solvent-free, non-toxic, tasteless, VOC release far below the national standard, is the most environmentally friendly building glue products.

2) no pollution

Conventional silicone sealants deposit silicone oil to contaminate the material, especially when used in porous materials such as stone and concrete, which can cause difficult to remove contaminants in the surrounding area. Is one of the main sources of building facade pollution, greatly reducing the aesthetic appearance and image value of the building, while MS sealant mechanism from the service of such defects, will not produce the same pollution.

3) Adhesion

In silicone rubber, polyurethane glue and MS glue, silicone adhesive is relatively weak, polyurethane adhesive strong, but need to cooperate with the primer, MS glue has excellent adhesive properties, to adapt to the vast majority Building substrates without primer bonding.

4) Weatherability

MS plastic molecular structure determines its good weatherability, long-term exposure to the outdoors can still maintain good flexibility, the gel itself will not produce bubbles, will not produce cracks, long-lasting bond strength, with good thixotropy and Extrusion, to adapt to outdoor, indoor, humid, low temperature and other operating environment.

5) Finishing

Traditional silicone sealants can not be coated with paints. They often need to be paired with exterior paints by toning their colloids. Their manufacturing process is time-consuming and laborious, making it difficult to guarantee the exact same colors and difficult to control costs. MS sealant can be directly in the colloidal surface finishing operations, not the vast majority of paint compatibility, avoid the troubled at the same time, the perfect realization of the color of the exterior uniform, so as to maintain the beauty of the main building. In addition, MS sealant does not produce pollution on the coating surface, paint can also extend the service life of sealants, but also reduce the overall cost. 6) Stress relaxation

As the construction substrate shrinks with the passage of time, there is a tendency that the seams will gradually expand, and the general sealant adhesive surface will bear a greater mechanical effect, and the sealant will crack and the adhesive surface will be damaged problem. MS sealant combines both stress and elasticity, even in the long-term tensile state, under the effect of stress relaxation, to minimize the impact of shrinkage of the construction substrate.
