MS glue is also called silane-modified polyether sealant. As it contains no formaldehyde and no isocyanate, it has outstanding environmental features such as solvent-free, non-toxic, tasteless, and low VOC release. It is friendly to the environment and human body. It adapts to most construction substrates and has good workability and adhesion. , durability and weatherability, especially non-pollution and paintability, have a wide range of applications in architectural decoration.
Compared with the mainstream construction sealants on the market, MS glue has the following characteristics:
1) Health and environmental protection
The traditional sealant (silicone gel) contains solvents, which can release formaldehyde, VOCs (Volatile Organic Compounds) and other hazards to people's physical and mental health. MS glue does not contain formaldehyde and isocyanate. It is solvent-free, non-toxic, odorless, and VOC release far below national standards. It is the most environmentally-friendly construction adhesive product.
2) No pollution
The traditional silicone sealant deposits silicone oil to contaminate it. Particularly when porous materials such as stone and concrete are used, it is difficult to remove the surrounding pollution. It is one of the major sources of pollution on the façade of buildings, which greatly reduces the aesthetics and image value of buildings. MS sealants, on the other hand, have overcome this type of defect mechanically and produce the same pollution.
3) Adhesion
In silicone adhesives, polyurethane adhesives, and MS adhesives, the adhesive strength of silicone adhesives is relatively weak, and the adhesive strength of polyurethane adhesives is strong, but it needs to be used with a primer coating. MS adhesives have excellent adhesive properties and can adapt to the vast majority of Building substrates without primer bonding.
4) Weather resistance
The molecular structure of MS gel determines its excellent weather resistance. It can maintain good elasticity even when it is exposed outdoors for a long time. The colloid itself will not generate bubbles and cracks. The adhesive strength is persistent and has good thixotropic properties. Extrusion, adapt to outdoor, indoor, humid, low temperature and other operating environments.
5) Finishing
Traditional silicone sealants cannot be coated with paints. They often need to be tinted with colloids to maintain the same color as exterior paints. The production process is time consuming and time-consuming, and it is difficult to ensure that the colors are exactly the same and the cost is difficult to control. MS sealant can be directly applied on the surface of colloidal coating. It is not that most of the paints are compatible and avoiding troubles. At the same time, the uniform color of exterior wall is perfectly achieved, so as to maintain the beauty of the main body of the building. In addition, the MS sealant contaminates the surface of the paint, and the paint can also extend the life of the sealant, further reducing the overall cost. 6) Stress relief
The building base material will shrink as time passes, leading to a tendency for the joints to slowly expand. The common sealant adhesive surfaces will undergo greater mechanical effects, cracks in the sealant and breakage of the adhesive surface, etc. problem. MS sealant combines both stress and elasticity. Even if it is stretched for a long period of time, the effects of stress relaxation can minimize the impact of building substrate shrinkage.
