TWO-COMPONENT EPOXY ADHESIVE FOR FRP STRENGTHENING SYSTEMS
DESCRIPTION
A two-component, solvent free epoxy based structural adhesive for strengthening with FRP laminates. ABABOND FRP-C5 has been designed for use in cold weather between 5 to 25 °C. It has excellent mechanical and chemical resistance. Also, due to its special rheology, the surface of the fibers will completely be saturated and the fibers will attach to the surface without slipping.
To achieve the best performance of the adhesive, the fibers must be completely saturated. This requires to use of 650 to 850 g/m2, which can be depending on the type and weight of fibers and conditions of execution.
All surfaces should be clean, dry and free from curing compounds, release agents, troweling compounds, standing water, grease, oil, dirt, bitumen coatings, all loosely adhered aggregates and cement particles, etc. Concrete must be cured for 28 days and its minimum compressive strength must be 20 N/mm2 and its minimum bond strength must be 2.5 N/mm2. All surfaces should be prepared with a sandblast or special tools and remove loose and unstable parts of concrete. A minimum surface profile of 50 to 70 μm is recommended.
Mix component A and B separately with a mixing paddle attached to a slow speed electric drill (max. 400 rpm). Add component B to component A and mix with the mixing paddle until the color of mixture changed into uniform gray.
Note1: Always mix an appropriate amount of material so that can be used before 30 minutes.
Note2: It is mandatory to follow mixing ratio of two components.
ABABOND FRP-C5 can be applied by means of a roller or brush or machine method. It is recommended to use a brush in order to obtain better coating and filling all the pores. The movement of the brush should be in the opposite direction of the fiber texture (unidirectional fibers) and in a reciprocating manner.
