Product overview:
Gtech@B320 is durable self-leveling sealing material specially designed by our company for rapid repair of road cracks. The product has the characteristics of single component, self-leveling, environmentally friendly, neutral curing at room temperature, good aging resistance, high and low temperature resistance, high stability and durability after curing.
Gtech@B320 sealant is one component, environment-friendly, non sagging, even and fine paste, neutral curing at room temperature. After curing, it has the characteristics of good aging resistance, high and low temperature resistance, high stability, low modulus, high elasticity, etc. It is specially designed for long-term aging resistance, sealing and waterproofing of expansion joints, deformation joints, etc. of ballastless tracks, airport runways, roads, tunnels, rail ways, bridges, floors, buildings, etc.. it has the features of low modulus, high displacement and good expansion recovery, and adapt to the rapid displacement of road joints. Artificial accelerated climate aging test shows that it has excellent weather resistance and can fully cope with the harsh environment test of high and low temperature and strong ultraviolet.
