JGN804 Crack injection resin
JGN804 Crack injection resin
◆ This adhesive has very low viscosity and strong penetration. Thus, it can be injected in micro-cracks with a width of 0.1mm.
◆ This adhesive has good performance in anti-aging and medium resistance (acid, alkali, water).
◆ This adhesive does not contain volatile solvents, and does not shrink when hardened.
◆ This adhesive has excellent toughness and impact resistance after curing.

Application:
◆ Concrete cracks (0.1~1.5mm) and internal defects (honeycombs, holes) are repaired by grouting.
◆ It is mainly applied to the concrete cracks of the ballastless track via the non-pressure injection method and the low pressure grouting method.
◆ Resin crack injection adhesive supporting tools
