Compared with silicone glue in the domestic construction sealant, MS glue has more and more prominent advantages:




1
Excellent environmental performance
MS glue production without solvent addition, formaldehyde-free toluene xylene and other harmful substances released by the human body, non-toxic, odorless, VOC content is the lowest, VOC release is far lower than national standards, environmentally friendly green, is the most environmentally friendly construction adhesive products .




2
Greater bonding range and strength
MS glue is not only suitable for most building materials, but also has good adhesion to porous plastic materials such as acrylic, ABS, plexiglass, etc., and has more and wider application than silicone rubber. Most building substrates do not require primer bonding.




3
Strong stability
MS glue will not escape oily molecular substances to contaminate the surface and seams of building materials, and maintain the appearance of the building for a long time. Silicone glue will precipitate small molecules, together with rain and dust, forming intractable stains on the exterior of the building.




4
Strong compatibility
MS glue is compatible with most paints and coatings. It can be directly painted on the surface of the gel. It can perfectly realize the uniform color of the outer wall and keep the building beautiful. However, the traditional silicone rubber will not be able to maintain the finish due to the shrinkage of the surface tension.




5
Good uniformity
The balance of MS gel's overall performance is also the best.




At the same time, MS glue also has the following characteristics:


Excellent gene


MS Polymer (MS polymer) main chain is a flexible segment of polyoxypropylene ether, using special molecular design and polymerization process, the molecular weight is between 12000-15000, it is very uniform in organic chemistry, stable performance, and silicon Advantages and advantages of ketone sealant and polyurethane sealant.


Excellent performance


1. Environmental protection: The terminal silyl polyether is a long-chain structure of a siloxy-terminated polyether. It does not contain toxic isocyanate groups and free isocyanates like polyurethane sealants; solvent-free, formaldehyde-free and extremely low. Volatile substances (far below national standards), non-toxic and tasteless, and more environmentally friendly.


2, weathering durability: silane modified polyether sealant after room temperature moisture curing will form a network structure of Si-O-Si bond as a cross-linking point with flexible polyether long chain connection, this system not only has excellent weather resistance Water resistance, aging resistance and durability, and can effectively inhibit and avoid the generation of surface cracks after long-term use of the sealant. Directly exposed, it meets the Japanese JS and national standard double standard (9030), and has heat and cold resistance in the environment of -30 ° C ~ 90 ° C.


3, substrate treatment: due to the low surface energy and high permeability of the base polymer (terminal silyl polyether), it has good wetting ability for most inorganic, metal and plastic substrates, the substrate can be produced simply Good adhesion.


4. Non-polluting: Since it does not add any volatile solvent or easy to migrate plasticizer, it does not contain silicone oil or silicone resin, and will not adsorb dust in the air and cause pollution.


5, mechanical properties: MS Polymer molecular structure and cross-linking properties determine the performance and quality of modified silicone sealant (MS glue), low modulus, suitable stress relaxation ability and high elastic recovery rate, can follow the structure Joint expansion and contraction and shear deformation caused by environmental effects such as thermal expansion and contraction, wind load, earthquake action, and uneven settlement.


6. Finishing: The surface of ordinary silicone sealant can't be painted and colored. It can only be blended into the color required by users according to user's requirements. The silane-modified polyether adhesive can be painted and colored, and has good finishability. Sex.




Broad market


MS glue is very popular because of its excellent performance. It is in the ascendant 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. Thousands of households.
