Products Features

One component, neutral cured silicone sealant.This product can produce superior adhesion to most building materials.

It has the following superior product features：

1、 Eeasy to use: can be extruded at any time;

2、Excellent thixotropy and extrusion, can be extruded under the conditions of -5℃-40℃;

3、Neutral curing: suitable for most building materials without adverse reactions or corrosion;

4、 In case of open fire does not support combustion, no fire self-extinguishing;

5、 After curing, keep good elasticity in -50℃-150℃ environmental conditions.

Applications

Silicone fire sealant is suitable for building fire joint sealing
