JS-901LM
High performance MS sealant

JS-901LM high-performance MSALL sealant is a high-quality, single component, paintable, and pollution resistant neutral modified sealant based on silane modified polymers. This product does not contain solvents and is pollution-free to the environment. At the same time, it can produce superior adhesion for most building materials without the need for a primer.

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, and cement components; No pollution to porous substances;

〔5〕 Excellent weather resistance, aging performance, and superior tensile and compressive resilience;

〔6〕 Neutral curing, non corrosive to building materials such as aluminum, steel, stone, prefabricated concrete components (PC board), cement fiber board, etc., overcoming the disadvantage of ordinary silicone adhesive that easily contaminates the substrate;

〔7〕 High displacement low modulus products: comply with the requirements of JC/T881-2017 "Building Sealants for Concrete Joints" standard 50LM level and GB/T 22083-2008 "Classification and Requirements for Building Sealants" standard 50 level.
