MSPolymerDichtstoffe

MSPolymerDichtstoffe are sealants and adhesive formulations based on MS polymer technology. MS polymer stands for modified silane-terminated polymer, a moisture-curing elastomeric polymer used to produce one-component or multi-component sealants. They are designed for construction and industrial use, offering a combination of adhesion, elasticity and weather resistance.

Curing and characteristics: MS polymer sealants cure through exposure to atmospheric moisture, forming a flexible, rubber-like joint. They are typically neutral-curing, which reduces corrosion risk for metals and compatibility with sensitive substrates. The curing mechanism allows rapid handling and progress in many environments, with low shrinkage and good long-term elasticity. Many products are formulated for low odor and low VOC emissions, making them suitable for indoor use.

Adhesion and substrates: These sealants adhere well to a wide range of substrates, including concrete, brick, natural stone, plaster, glass, metal, ceramic, wood and many plastics. Primer requirements vary by product and substrate, but MS polymer sealants often bond well without primer on common construction materials. They are valued for their ability to seal joints in glazing, façades, bathrooms, kitchens and other areas subjected to movement, moisture or temperature fluctuations.

Applications and performance: MSPolymerDichtstoffe are used for expansion joints, glazing seals, sanitary seals and general bonding where elasticity and weather resistance are required. They offer compatibility with many coatings and paints, though some paints and sealant combinations require testing. Compared with silicone sealants, MS polymer variants usually provide better adhesion to porous substrates and easier handling, while remaining highly resistant to UV and weathering.
