MComp^® FRP Lining on Concrete Substrate

MComp® FRP(Fiberglass Reinforced Plastic) industrial linings is the most economical solution to overcome corrosion problems on a concrete substrate. By selecting the appropriate resin system such as polyester or vinyl ester resin, the chemical resistant FRP lining can withstand acids and alkalis at both room and elevated temperature. Layers of E-glass type of chopped strand mats were used to enhance the mechanical strength and durability of the lining followed by a final layer of C-glass tissues. The glass tissue will act as light weight reinforcing mats to provide a resin rich smooth surface which increases corrosion resistance without the grazing that would occur in non-reinforced resin.

To maximise the bonding between the FRP and the concrete substrate, the new concrete must be cured for a minimum of 28 days. The concrete must be dried, cleaned and free of all contaminates and dirt. Roughening of concrete by sanding, grinding, or shot-blasting must be completed for adhesion to concrete substrate. The curing time is 8-10 hours for foot traffic, 24 hours for heavier service and chemical spillage and full cure at 7 days at 21° C.
