Concrete Crack Repairing Grout Epoxy
Crack Repair Grouting adhesive
XQ-FF31 Hi-Mod Gel High-modulus, high-strength, structural, epoxy
paste adhesive
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.
Usage
Structural bonding of concrete, masonry, metals, wood, etc. to a
maximum glue line of 1⁄8 in. (3 mm).
Grout bolts, dowels, and pins.
Seals cracks and around injection ports prior to pressure-injection
grouting.
Interior, vertical, and overhead repair of concrete as an epoxy
mortar binder.
As a pick-proof sealant around windows, doors, lock-ups etc. inside
correctional facilities.
Advantages
Meets physical requirements of China National Standard.
Excellent adhesion to concrete, masonry, metals, wood, and most
structural materials.
Paste consistency ideal for vertical and overhead repair of
concrete.
Fast-setting and strength-producing adhesive.
Convenient easy mix ratio A:B = 3:1 by volume.
