Product Description

Description
GUIBAO 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), GUIBAO 668 exhibits outstanding performance in highway, airport, bridge and other concrete joints where high movement occurs. Accelerated weather aging test proves that GUIBAO 668 is definitely qualified to withstand the temperature extremes and strong violet rays of concrete pavement. Once exposed to moisture in the air, GUIBAO 668 begins its room temperature cure to form an elastic silicone rubber with lasting weatherproofing seal performance.

Basic Uses
GUIBAO 668 pavement silicone sealant is specially formulated for
  1. Sealing the transverse, longitudinal, center lines and shoulder joints of concrete pavement.
  2. Sealing the extension and contraction concrete joints of high ways, airports, bridges, warehouses, parking lots, stadiums, architectural settlements, etc.
  3. It can be used as original sealant in new concrete constructions or as remedial/ repair sealant for old constructions.
Features
  1. One part, ready to use as supplied ,good gunnability, dispensed directly from container into joints; by hand or with an air-powered pump;
  2. Excellent unprimed adhesion and bonding to concrete;
  3. High movement capability-able to accommodate the extension and contraction, and shear deformation of concrete joints without itself being destroyed;
  4. Low modulus-able to stretch in the joint with little force. This can   better protect the concrete surfaces from being damaged;
  5. Resilient-once cured, strong anti-embedding performance, preventing   gravels and other incompressible into the joints which may result in   joint edge failure ; 
  6. Highly elasticity and extension recovery-the sealant can be stretched to   100 percent or compressed to 50 percent of the joint width ;  
  7. When   released, it will resume its original shape without splits or cracks ;
  8. Excellent temperature extreme resistance -cured GUIBAO 668 has a   stable performance over the temperature range from -60ºC to +150ºC;
  9. Excellent lasting weatherability-the Si-O-Si high energy bond can not   be destroyed by UV or ozone.
Colours
GUIBAO 668 is available in black, grey and other customized colours.

Packaging
GUIBAO 668 is available in disposable cartridges (net 300ml), sausages (net 590ml) and in pails (25kg).

L imitations
GUIBAO 668 should not be applied: 
  1. In totally confined spaces as sealant requires   atmospheric moisture for cure .  
  2. To frost laden or damp concrete surfaces .  
  3. When substrate surface temperature is below 4ºC or   over 40ºC .
  4. New concrete should be allowed to cure and dry for   at least 28 days of good drying weather. For each   day of rain that occurs during that period, an   additional day should be added to the 28-day drying   time.
  5. For fast completion and or high early concrete   mixes, please contact Guibao Technical Services The sealant bead should be recessed below the   surface of concrete surface to prevent abrasion from   traffic and snow removal equipment. 
  6. The adhesion to substrates other than concrete   should be checked before performing full-scale   sealing.
S afety Information
  1. GUIBAO 668 is a chemical product, not edible, no   implantation into body and should be kept away   from children. 
  2. Cured silicone rubber can be handled without any   risk to health. 
  3. Wear gloves for sealant application .
  4. Should uncured silicone sealant contact with eyes, rinse thoroughly with water and seek medical   treatment if irritation persists; should contact with   skin, wipe off with cloth, then wash with sopy   water .  
  5. Avoid prolonged exposure of skin to uncured   silicone sealant. 
  6. Good ventilation necessary for work &cure places . GUIBAO 668 Pavement Silicone Sealant GUIBAO 668 Pavement Silicone Sealant GUIBAO 668 Pavement Silicone Sealant GUIBAO 668 Pavement Silicone Sealant
