The full name of MS sealant is modified silane polyether sealant, which is a new generation of building sealant developed after polysulfide sealant, silicone sealant and polyurethane sealant. It is mainly used in bonding, caulking, jointing, sealing, waterproofing and reinforcement in construction engineering and decoration; in recent years, as people's understanding of the advantages of MS sealant itself continues to deepen, its application in industrial fields such as refrigerated trucks, containers and elevators is also expanding.

With the development and understanding of MS sealant, under the requirements of some specific application scenarios, the demand for transparent MS sealant has also ushered in development, especially in the field of home decoration. This colorless and transparent colloid not only has the effect of bonding and sealing, but also takes care of the application scenario without the addition of mixed colors, so-called killing two birds with one stone.
Features of MS sealant.

1. Excellent environmental performance: No solvent is added in the production of MS sealant, no formaldehyde, toluene, dimethylbenzene and other harmful substances to the human body are released, and the VOC content is the lowest, which is environmentally friendly and green;
2. A wider range of bonding and stronger bonding strength. MS glue is not only suitable for most building materials, but also has good adhesion to acrylic, ABS, organic glass and other engineering plastics and porous materials such as concrete;
3. It will not release oily molecules to pollute the surface and joints of building materials, and maintain the beauty of the building for a long time;
4. It is compatible with most paints and coatings, and the surface of the colloid can be colored and painted;
5. Good overall performance balance;

Since the MS resin system is very sensitive to water vapor, hydrophilic fumed silica is generally not applicable in terms of storage stability. At present, the more common solution in the industry is to use hydrophobic fumed silica, and its specific hydrophobic type can be selected according to the actual situation of the customer.
