Low modulus MS sealant
JS-900LM low modulus MS sealant is a high-quality, single 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 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, prefabricated concrete components (FC boards), cement fiber boards, etc; No pollution to porous substances.
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 fine, steel, stone, prefabricated concrete components (PC board), cement fiber board, and other materials, overcoming the easy pollution of ordinary silicon steel adhesive
The drawbacks of the substrate.
