1.Perfusion construction，more fluid

Low-density pouring crack glue in order to be easier to use injection gel, more smooth, more quickly through the cracks to each corner like water flow.

2. Avoid mixing air

The glue can be used to prevent the air from being mixed into the air and ensure the effective infusion area.

3. No leakage

Glue does not leak, and the substrate tightly together to achieve a better injection effect

4. Reduce costs

The density of the filling glue is small and the volume unit is large, so that can fill more cracks and reduce the cost.
