Low modulus, high displacement capability, adapt to the displacement of concrete road joints.
The artificial accelerated weathering test shows that its excellent weatherability is fully qualified for the harsh test of high and low temperature and strong ultraviolet environment of concrete road surface.
When use, the sealant is injected from the package to the seams that have been cleaned. The sealant forms elastic silicone rubber under the action of moisture in the air at room temperature, and forms a long-lasting bond and durable seal in place.
