COGRI Bondcoat is a two part epoxy resin system consisting of a base component containing solvent free epoxide resin plus a low viscosity liquid hardener.
COGRI Bondcoat is applied using a stiff bristle brush to give a thin continuous bond layer to clean prepared surfaces.
COGRI Bondcoat is used as a bonding primer where the highest bond values are required. The bonder is used for applications of epoxy resin based mortars to resin and cementitious substrates in addition to cementitious mortars and concretes applied to existing concrete surfaces. The bond values achieved are greater than the tensile strength of high quality concrete. Bond lines are resistant to a wide range of chemicals to compliment the applied topping.
Typical Properties @ 20°C
- Tensile Strength: 41N/mm_
- Flexural Strength: 65N/mm_
Adhesion To Concrete:
The bond strength of COGRI Bondcoat to concrete will
be greater than the tensile strength of the concrete.
Testing to failure will result in the rupture of the
Pot life of COGRI Bondcoat is 1 hour.
Depending on the topping, the finished application
may be brought into light use in 24 hours.
Full cure will be obtained in 7 days.
COGRI products are manufactured under a quality
