GB 668 is specially designed for the lasting weatherproofing seal of concrete joints. Because of its low modulus and excellent extension and compression recovery (+100/-50 percent of original joint width), GB 668 exhibits outstanding performance in highway, airport, bridge and other concrete joints where high movement occurs. Accelerated weather aging test proves that GB 668 is definitely qualified to
withstand the temperature extremes and strong violet rays of concrete pavement. Once exposed to moisture in the air, GB668 begins its room temperature cure to form an elastic silicone rubber with lasting weatherproofing seal performance.
FEATURES:
- 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.
- Low modulus-able to stretch in the joint with little force. This can better protect the concrete surfaces from being damaged.
- Resilient-once cured, strong anti-embedding performance, preventing gravels and other incompressible into the joints which may result in joint edge failure.
- Highly elasticity and extension recovery-the sealant can be stretched to 100 percent or compressed to 50 percent of the joint width. When released, it will resume its original shape without splits or cracks.
- Excellent temperature extreme resistance -cured GB 668 has a stable performance over the temperature range from -60℃ to +150℃
- Excellent lasting weatherability-the Si-O-Si high energy bond can not be destroyed by UV or ozone.
