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. |
|
THE CHALLENGES :- |
♦ 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. |
|
ABOUT COLDBOND |
► 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. |
|
APPLICATION AREA |
♦ RCC to PCC interface, |
♦ RCC to RCC joints, |
♦ RCC (Beam / Column) to Masonry joints, |
♦ RCC / PCC Bricks to Coving joints, |
♦ PCC / Plaster to PCC / Plaster (repair) interface, |
♦ RCC / Bricks to Plaster interface. |
|
APPLICATION METHOD :- |
♦ Use ColdBond as it is or in diluted form (with potable water @ 1:1) based on the application need. |
♦ Spray / Brush apply on the construction joints of concrete, plaster or bricks. Construction Window after applying ColdBond : up to 72 hours. |
|
COVERAGE :- |
♦ 40-50 ft²per litre for undiluted ColdBond. |
♦ 80-100 ft²per litre @ 1:1 dilution (Coverage may vary depending upon surface roughness). |
