Description KLAI-308 cement-based permeable crystallization waterproof coating is one kind of green environmental protection waterproof material, suitable for concrete waterproofing project.After compound with water,brushing on the concrete surface, taking water as the carrier with the infiltration of water on the structure of the pores of the active chemical substances, it can advance the density of concrete,reinforce the strength of concrete and protect the rebar.
Feature (1)The Waterproof performance is permanent
(2)Protect concrete-this coating can advance the density of concrete,reinforce the strength of concrete and protect the rebar.
(3)The crack on concrete could be self-healing,the active substance in the coating could be activated by water at any time,the hydration reaction will continue in the concrete, the crystal will generate to block the crack.
(4)Excellent penetration resistance after grind off coating-- the specimen which after painted with the coating 56days, the penetration pressure ≧ 0.8MPa(according GB18445-2012)
(5)will no impact the air permeability of concrete body
(6)The coating has good adhesive and strength
