Do you really understand MS Sealant?
The MS polymer is a crosslinked polymer based on a silane-terminated polyether. According to the coating online, MS polymer-based products contain no silicone components and solvents, no polyurethane groups, most formulations are odorless and sprayable, and the inherent elasticity of MS adhesives and sealants absorbs and compensates for dynamic loads. Uniform transmission of force to prevent premature fatigue of the material, MS-based material can achieve a variety of substrate bonding.
Development status
MS glue is also called silane-modified polyether sealant. Due to the absence of formaldehyde, no isocyanate, it has outstanding environmental protection characteristics such as solvent-free, non-toxic and tasteless, low VOC release, and is friendly to the environment and human body. It adapts to most building substrates and has good workability and cohesiveness. Durability and weather resistance, especially non-polluting and paintable, have a wide range of applications in architectural decoration.
The main advantage of MS glue
Health and Environmental Protection
The traditional sealant (silicone gel) contains formaldehyde, which releases formaldehyde, VOC (volatile organic compounds) and other health hazards. MS glue is formaldehyde-free and isocyanate-free. It is solvent-free, non-toxic, odorless, and VOC release is far below national standards. It is the most environmentally friendly construction adhesive product.
No pollution
Conventional silicone sealants deposit silicone oil, which causes contaminants to adhere to them. Especially when used in porous materials such as stone and concrete, it is difficult to remove the surrounding pollution. It is one of the main sources of pollution on the facade of buildings, which greatly reduces the aesthetics and image value of the building. MS sealant overcomes such defects in mechanism and does not cause the same pollution.
Cohesiveness
In silicone rubber, polyurethane glue and MS glue, the silicone rubber has relatively weak adhesion, and the polyurethane adhesive has strong adhesion, but it needs to be used together with the primer. MS glue has excellent bonding performance and can adapt to the vast majority. Building substrate without primer bonding.
Weather resistance
The molecular structure of MS gel determines its good weatherability. It can maintain good elasticity when exposed to the outdoors for a long time. The colloid itself will not generate bubbles, will not crack, and the bond strength will last for a long time. It has good thixotropy and Extrudability, adapt to a variety of operating environments such as outdoor, indoor, wet, low temperature.
Finishing
It is understood that the traditional silicone sealant can not be coated with paint, and it is often necessary to maintain the color of the exterior paint by coloring the colloid. The production process is time-consuming and laborious, not only the color is difficult to guarantee the same, but also the cost is difficult. control. MS sealant can be directly applied to the surface of the colloid. It is not compatible with most coatings, avoiding the troubles and perfectly achieving the uniform color of the outer wall, thus maintaining the aesthetic appearance of the main body. In addition, MS sealant does not cause contamination on the surface of the coating. The coating can also extend the life of the sealant and reduce the overall cost.
Stress relaxation
The building substrate will shrink with time, which will lead to the tendency of the joint to expand slowly. The common sealant bonding surface will bear a large mechanical effect, and the sealant will be broken and the bonding surface will be damaged. problem. MS sealant combines stress and elasticity. Even if it is stretched for a long time, it can minimize the impact of shrinkage of building materials under the effect of stress relaxation.
Main field of application
The advantages of MS glue in the assembly field are obvious. For example, in the assembly process, the biggest advantage of MS glue is that it can simplify the operation process, shorten the construction period, improve the production efficiency, without the need of primer, and has good adhesion to various substrates; It can replace some hot melt adhesives, modified hot melt adhesives and special mechanical fastening methods. MS glue is also an important advantage for workers without side effects. At the same time, the application of MS glue can reduce energy consumption, and it can be sprayed at room temperature; the advantage of product sprayability is particularly obvious in the assembly industry.
MS glue is widely used in industry due to its good adhesion to plastics, metals and wood materials. In the case of home-installed flooring, due to its rapid curing, it quickly reaches the bonding strength and is easy to clean. It can easily remove the glue remaining on the floor surface and keep it clean and has a large space for application.
development trend
Coating Online believes that the market is broad, the potential is huge, the awareness of human environmental protection is increasing, the relevant laws and regulations are becoming more and more stringent, and the promotion of environmentally friendly adhesives is an inevitable trend. MS glue is popular because of its environmentally friendly green color. It is emerging in Europe and the United States. It has even occupied half of the sealant market in Japan. In China, with the yearning for green life and the pursuit of environmental protection, MS glue will also enter every family soon.
