Who is MS sealant?

The MS of MS sealant is the abbreviation of Modified Silicone, and the corresponding Chinese equivalent is modified silane polyether sealant. It is mainly a single-component or two-component elastic sealant made of MS polymer as the base polymer, combined with fillers, plasticizers and other functional additives. It is a successor to silicone rubber (SR) and polyurethane rubber (PU). ) is a new generation of building sealant developed after. Mainly used in bonding, caulking, joints, sealing, waterproofing, reinforcement and other fields of construction engineering and decoration. As people's understanding of the advantages of MS sealant continues to deepen, its application in the refrigerated trucks, containers, and elevator industries is also expanding.

The historical development of MS sealant

MS sealant was first born in Japan in 1979. A Japanese chemical industry company successfully developed a silicone-modified polyether sealant (also known as silyl-terminated polyether sealant) base polymer to solve the shortage of natural resources in Japan. The lack of cement and yellow sand brought about by the cement sand can be used as a substitute for bonding, caulking, sealing and waterproofing in construction projects and decoration.

In 1980, Japan first prepared an elastic sealant based on silane-terminated polyether, and began to promote its application in large buildings and high-end buildings in 1981.

After 1982, Japan, the United States and European countries competed to conduct research on terminal silyl polyether base polymers and their elastic sealants and elastic sealants, which promoted the rapid development of MS sealants.

In recent years, MS sealant has emerged as a new force, the number of manufacturing companies has continued to increase, and related technologies have progressed rapidly. After its civilian use, it has occupied an increasing share in the world's construction sealant market.

The actual effects and suggestions of the above performance in home decoration applications are summarized as follows:

1.MS sealant is the healthiest and most environmentally friendly

It can be seen that MS sealant performs best in terms of colloid release odor and surrounding pollution.

This depends on the raw material composition of various types of sealant. The composition of silicone sealant, polyurethane sealant and polysulfide sealant often include various solvents, and the solvents are often volatile benzene such as toluene, xylene, etc. Solvent-like substances will evaporate large amounts of formaldehyde and other harmful gases for decades, affecting the health of residents. This is the reason why people used to "talk about discoloration of sealant".

The composition of MS sealant does not contain any harmful solvents and does not emit free formaldehyde and other substances harmful to the human body. It is a new type of odor-free and environmentally friendly sealant that can achieve a safe level in terms of health and environmental protection. It can be used in almost every scene at home, from the kitchen to the bathroom to the living room and bedroom, and you will feel more at ease when using it. Especially if there are children, pregnant women and pets at home, they all need to make careful choices when choosing sealant.

2.MS sealant has excellent anti-mildew effect

Comparing the anti-mildew effects of various types of sealant, you must understand the anti-mildew principles of various types of sealant.

Silicone sealant, polyurethane sealant and polysulfide sealant all achieve anti-mold effects by adding anti-fungal agents. The raw materials of anti-fungal agents are powerful fungicides, which can have a strong effect on common molds, fungi and bacteria. Killing effect. However, the effect of antifungal agents is time-sensitive. As the antifungal agents evaporate, the antifungal effect of these sealants gradually disappears. Moreover, the chemical formula of this type of sealant is very active, so it is easier to breed bacteria, so it usually becomes moldy after 3 to 6 months of use.

MS sealant achieves long-term mildew resistance through a unique molecular formula. The raw materials it uses are MS-Polymer resin and inorganic nanomaterials. The chemical structural formula of this material has no molecular structure, which means that it will not have pores, so in fact The molecular structures of glass and aluminum alloys are very similar. Who has ever seen glass and aluminum alloys become moldy? Therefore, MS sealant fundamentally eliminates the chance of mold growth and has the best anti-mold performance among several types of sealant currently on the market.
