Two component MS sealant
JS-902LM low modulus MS sealant is a high-quality, two component, paintable, and pollution resistant neutral modified sealant based on silane modified polyether polymers. This product does not contain solvents and is pollution-free to the environment. At the same time, it can produce superior adhesion to most building materials.
Product features
〔1〕 Environmental protection products: solvent-free, PVC free, isocyanate free, non-toxic, odorless, pollution-free, and fast curing;
〔2〕 Surface Applicability: Compatible with most industrial paints, it can be sprayed after surface drying, which does not affect the curing rate;
〔3〕 Easy to use: excellent thixotropy and extrudability, wide temperature range.
〔4〕 Good adhesion: Excellent adhesion performance for most building materials such as stone, aluminum, ceramics, prefabricated concrete components (PC board), cement fiber board, etc.; no pollution to porous materials.
〔5〕 Excellent weather resistance, aging performance, long-term superior tensile, compressive, and shear stress traceability, while the good weather resistance of the sealant ensures the durability and excellent waterproofing of the seal;
〔6〕 Neutral curing, non corrosive to building materials such as aluminum, steel, stone, prefabricated concrete components (PC board), and cement fiber board, overcoming the disadvantage of ordinary silicone adhesive that easily contaminates the substrate.
