The development of high-rise buildings and specialized construction methods has put forward higher requirements for the performance of waterproof materials, adhesives, and sealants, especially in terms of environmental protection, energy conservation, and aesthetics. Therefore, the high-performance modified silicone (MS) adhesive has attracted people's attention since its appearance, and its market share in the world sealant market has steadily increased. The market share of MS sealant for construction in Japan exceeds 35% and remains in the top position in terms of market share. According to relevant survey reports, the market share of MS adhesive in the European sealant material market is about 10%. With the growth of the Chinese economy, especially the development and upgrading of construction methods, concepts such as residential industrialization (housing industrialization) and site-specific material selection have gradually become familiar to people. Develop MS adhesive suitable for the characteristics of Chinese architecture, which has a wide range of applications as a sealing and bonding material in construction.

Characteristics of MS sealant

MS sealant is pollution-free

For external decorative materials, traditional building sealants are one of the main sources of pollution, which can have a serious impact on buildings and greatly reduce their aesthetic appeal and image value. Silicone sealant can cause hydrophobicity around the joint, leading to the attachment of pollutants, especially when used for porous materials such as stone and concrete, which can cause difficult to remove pollution around the joint. However, MS sealant overcomes such defects from a mechanistic perspective and does not produce the same pollution. If MS sealant is used during the renovation of exterior walls, it can be easily painted on the surface, overcoming the shortcomings of silicone sealant in this regard. In the European and American construction markets, MS sealant is often used as a sealing material for open parts such as window frames; MS sealant has achieved excellent results in Japan for more than 30 years and has also been applied and developed in China.


Coating properties of MS sealant

Generally speaking, traditional silicone sealants cannot be coated with paint and often require color adjustment of the gel to maintain consistency with the exterior wall paint. The production process is time-consuming and labor-intensive, and not only is it difficult to ensure exact color consistency, but the cost is also slightly higher. If the coating can be directly applied on the surface of the colloid, it can avoid such problems and achieve perfect uniformity of exterior wall color. The surface of MS sealant can be well coated and compatible with the vast majority of coatings, meeting the market demand for such applications. In addition, MS sealant does not contaminate the surface of the coating after coating, and the coating can also extend the service life of the sealant while reducing the cost of renovation and refurbishment.

Mold resistance of MS sealant

In daily life, it is often found that the surface of ordinary sealant is blackened and covered with mold, especially in damp places such as kitchens and bathrooms. Even products labeled as anti mold glue can still experience this phenomenon because the anti mold agent is prone to migration and penetration onto the surface of the glue. After being washed away by water or other substances, it will lose its original anti mold properties. MS POLYMER® It has good compatibility, which can make it work better and maintain the long-term and effective beauty and cleanliness of the sealed area. Through relevant tests, it can be found that there is a performance difference between ordinary anti mold glue and MS anti mold glue.


Stress relief of MS sealant

Prefabricated fiber cement boards are becoming increasingly popular in prefabricated residential construction projects. Due to internal reactions and long-term moisture release, prefabricated fiber cement boards tend to shrink over time after construction, resulting in a gradual expansion of joints. If ordinary sealant is used, its bonding surface will bear significant mechanical effects, which is highly likely to cause problems such as sealant rupture and bonding surface damage. Therefore, in response to the use of paneling in residential buildings, MS sealant has successfully developed a product that can withstand stress while also possessing elasticity. As the joint expands, although the sealant is in a stretched state for a long time, it can minimize the shrinkage effect of the cement board under the action of stress relaxation.

In recent years, the use of paneling has been the main construction material for residential industrialization. Especially with changes in design concepts and improvements in building durability, the proportion of use of stress relieving MS sealant in single family homes and low rise residences continues to increase, thereby increasing the usage of stress relieving MS sealant.
