A, product characteristics:
1, this product is liquid, easy to tiny cracks in the concrete repair.
2, damage to buildings and structures, the pouring sealant reinforcement, can be effective in restoring its integrity, and the appearance of damage.
3, do not contain volatile solvent, not shrinking hardening.
4, good toughness and impact resistance.
5, long operation time, curing adhesive strength.
6, good resistance to water, oil, alkali and acid medium capacity.
Two, the scope of application of:
1, applied to the cracks in reinforced concrete crack repair, filling repair construction crack concrete walls, floor, underground chamber.
2, widely used in steel bonded steel, bridge strengthening engineering.
