Good genes

The main chain of MS Polymer is a flexible segment of polyoxypropylene ether. It adopts a special molecular design and polymerization process. Its molecular weight is between 12000-15000. It can be regarded as very uniform in organic chemistry, with stable performance and silicon. The advantages and strengths of ketone sealants and polyurethane sealants.

Excellent performance

1.Environmental protection

Silyl-terminated polyether is a long-chain structure of siloxy-terminated polyether, and does not contain toxic isocyanate groups and free isocyanates like polyurethane sealants; it is solvent-free, formaldehyde-free, and has very low volatile substances (far from Far below national standards), non-toxic and tasteless, with better environmental protection.

2. Weather-resistant and durable

The silane-modified polyether sealant will form a network structure connected by long-chain flexible polyethers with Si—O—Si bonds as crosslinking points after moisture curing at room temperature. This system not only has excellent weather resistance, water resistance, and Aging and durability performance, and can effectively prevent and avoid surface cracks of the sealant after long-term use. Directly exposed to use, meets Japanese JS and national standard double standards (9030), and has heat and cold resistance in the environment of -30 ° C to 90 ° C.

3. Substrate treatment

Due to the low surface energy and high permeability of the base polymer (silyl-terminated polyether), it has a good wetting ability to most inorganic, metal and plastic substrates. Simple handling of the substrates can produce good adhesion.

4.Non-polluting

Because it does not add any volatile solvents or easily migrated plasticizers, it does not contain silicone oil and silicone resin, and does not adsorb dust in the air to cause pollution.

5. Mechanical propertie

The molecular structure and cross-linking properties of MS Polymer determine the performance and quality of the modified silicone sealant (MS adhesive), which has a low modulus, suitable stress relaxation ability and high elastic recovery rate, and can follow the thermal expansion and contraction of the structure. Expansion and shear deformation of joints under environmental influences such as wind load, earthquake action, and uneven settlement.






6, finishing


The surface of ordinary silicone sealants cannot be painted and painted, and can only be formulated according to user needs. The silane-modified polyether adhesive can be painted and painted, which has good paintability.
