Neutral silicone sealant for engineering purposes
JS-222 neutral silicone sealant is a single component, neutral curing adhesive. The JS-222 product can produce superior adhesion to most building materials.
Product features
1. Easy to use: can be squeezed out for use at any time;
2. Excellent thixotropy and extrudability, which can be extruded at - 5 ℃ - 40 ℃;
3. Good adhesion, excellent adhesion to most building materials;
4. Excellent weather aging resistance;
5. It is non corrosive to concrete, marble, granite and other building materials, and overcomes the shortcomings of acid glue (ordinary glass glue) corrosive materials.
6. After curing, maintain good elasticity under environmental conditions of -50 ℃ -150 ℃.
