Atul provides systems with variable pot life, glass transition temperature and curing time. Variable pot life makes it suitable for small to very large jobs. Excellent mechanical properties such as tensile, flexural, shear and compressive strength can be achieved if the epoxy is applied with glass or carbon fiber reinforcement on concrete surfaces. Features • solvent-free • variable viscosities and setting time • high penetration in concerte surfaces • low shrinkage • excellent adhesion to concrete • creates a solid barrier against water penetration • maintains structural integrity and extends life • may be applied by gravity pouring | injection grouting Applications • old structures like bridges, beams, columns, buildings and road cracks Application process Clean the concrete surface thoroughly using wire brush | hand tool. Fill surface defects | undulances using epoxy mortar | paste. Apply epoxy primer on the surface. Mix resin and curing agent. Stir well. 1 4 2 3 Apply fibre on the primed surface when it is slightly tacky. Start application by brush | roller and ensure thorough impregnation of fibre with epoxy system. 5 Leave it for a minimum of 24 hours to achieve optimum strength. 6 12 13 Concrete structure strengthening systems Lapox systems Mixing ratio (resin : curing agent) Mixed1 viscosity @ 25 °C Pot life2 @ 25 °C Colour Recommendations Parts by weight mPa s Minutes Gardner Fast cure ARL-135 | AH-334 100 : 32 700-1,200 25-35 Resin: 2 GS Curing agent: 4 GS Fast curing low viscosity system for quick impregnation of glass and fibres for high mechanical strength.
