High Strength Epoxy Concrete Crack Sealer For Building Retrofitting
Features with high hardness, excellent Polish, strong adhesion,
fast curing, easy to bond with the substrate such as concrete,
stone, steel. Is a modified epoxy, initial adhesiveness.
Range of Application
Assorted with XQ-GF crack grouting adhesive when repairing concrete
cracks,
Mainly used for crack sealing and base bonding during processing of
repairing the concrete crack and grouting.
Sealing around the steel plate during steel wrap process
Repairing and leveling for the concrete surface.
Used for steel bar planting at secondary structure part.
Features
1, Low temperature or room temperature curing, fast curing speed;
2, Modified epoxy resin, good initial adhesiveness;
3, high adhesive strength after curing, good hardness and a certain
toughness;
4, Good anti-acid after curing, good performance against moisture
water, oil, dust,humidity and weather ageing
5, The cured products have good strength for tension, pressure and
bonding
