FT-900
General

JS-900 Universal 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, 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 stone and cement, overcoming the disadvantage of ordinary silicone adhesive that can easily contaminate the substrate.
