pavement sealant, concrete sealant, PC sealant, precast concrete sealant, building sealant
Basic Uses
GUIBAO 668 pavement silicone sealant is specially formulated for
- Sealing the transverse, longitudinal, center lines and shoulder joints of concrete pavement.
- Sealing the extension and contraction concrete joints of high ways, airports, bridges, warehouses, parking lots, stadiums, architectural settlements, etc.
- It can be used as original sealant in new concrete constructions or as remedial/ repair sealant for old constructions.
- One part, ready to use as supplied ,good gunnability, dispensed directly from container into joints by hand or with an air-powered pump
- Excellent unprimed adhesion and bonding to concrete
- High movement capability-able to accommodate the extension and contraction, and shear deformation of concrete joints without itself being destroyed

Adhesion test
GUIBAO 668 exhibits excellent unprimed adhesion to concrete. But due to the diversity of concrete configuration and substrate surface cleaning status, we can not guarantee that GUIBAO 668 is applicable for all concrete. Adhesion testing should be conducted prior to the large scale site application.
