What Are The Characteristics of MS Polymer?

The ms polymer has the dual advantages of aging resistance and high strength, so the bonding strength is high, the aging resistance is excellent, and it is widely used in the self-adhesion and mutual adhesion between metals, plastics, glass and other materials, and the sealing of gaps and contacts. No isocyanate, no PVC, no solvent, friendly to human body, health and environmental protection.

Silane modified sealant is a kind of high performance and environmental protection sealant prepared by end-silyl polyether/polyurethane (polyether/polyurethane as the main chain, both ends are sealed with siloxane) based polymer. Because it has the advantages and advantages of silicone sealant and polyurethane sealant, showing excellent weather resistance, durability, high deformation resistance and displacement ability, good adhesion, coating, environmental friendliness, low contamination, low viscosity and excellent operability, has been more and more attention of the domestic construction industry. In the industrial fields such as automobile manufacturing, rail transit, container manufacturing, equipment manufacturing, electronics and other fields are also being more and more widely used.

1.Extensive bonding to the substrate

Due to the low surface energy and high permeability of the base polymer (terminal silyl polyether/polyurethane), ms polymer has good wetting ability for most inorganic, metal and plastic substrates, and thus produces good adhesion to the substrate.

2.Excellent weather resistance and durability

The ms sealant has polyether/polyurethane as a long chain and silanoxy group as the end, polyether/polyurethane long chain has the characteristics of low unsaturation, high molecular weight and narrow distribution, and the end group is hydrolyzed siloxane group. Silane modified sealant can form a network structure with Si-O-Si bond as the crosslinking point. This system not only has excellent weather resistance, water resistance, aging resistance and durability, but also can effectively inhibit and avoid surface cracks after long-term use of the sealant.

3.Environmental protection property

MS polymer sealant is a silanoxy-terminated polyether with a long chain structure, which does not contain toxic isocyanate groups and dissociated cyanates like polyurethane sealant. The modified silane sealant has low viscosity, good operability, and no need to use organic solvents to adjust the process operation performance of the formulation, so silane modified polyether adhesive can be completely without adding any organic solvents, and its total volatile organic compounds (VOC) is very low.

4.Panitable

The surface of ordinary silicone sealant can not be painted, and can only be adjusted to the color required by the user according to the needs of the user; The modified silane sealant can be painted and painted, and has good coating property.

The modified silane sealant has attracted more and more attention because of its wide range of adhesive materials, environmental protection and excellent weather resistance. According to the classification statistics of Japanese building sealants, modified silane sealants have always occupied the first place in the Japanese sealants market share since 1995. In recent years, the market share in the European sealant market is also gradually expanding.
