Cold Bond is an acrylic based high performance bonding agent that is reactive and flexible for
use in concrete/concrete and concrete/plaster joints. It exhibits a pull off adhesion strength 2 equal to 34 kN/cm and is highly water resistant ensuring a permanent joint between structures.Joint between the old & newly cast part becomes a weak link due to migration of water from newly cast concrete to cured side.
PCC / RCC are cast in parts, leading to joints which develop cracks due to thermal cycling and
shrinkage stresses. The junction of PCC or RCC structures with bricks walls also has joints
which develop cracks. This leads to seepage / leakage.A new generation of acrylic copolymer technology
Exhibits dual properties of reactive and acrylic copolymer Imparts very high strength through molecular level reactive bonding Makes the joining interface water resistant Ensures flexible polymeric film formation at the interface.This results in formation of a very strong and flexible bond, and creation of monolithic joints.
Boil testing of simulated joint done with ColdBond confirms water resistance & wet bond strength.
