Polymer cement-based permeable crystalline high activity waterproof coating

Polymer cement-based permeable crystalline high activity waterproof coatingThe cement-based permeable crystalline waterproof coating is mainly composed of Portland cement, selected quartz sand, special active chemicals, etc. It is a gray powder material. The waterproof mechanism is based on water as a carrier, guided by water and with strong permeability, it is transported and filled in the micropores and capillaries of concrete, undergoes biological reactions, and forms insoluble dendritic crystals. The crystal and concrete structure are combined to form a closed waterproof layer, which blocks water flow and other liquid erosion from any direction. To achieve the purpose of waterproofing and chemical corrosion resistance, while also protecting steel bars and enhancing the strength of concrete structures.

Polymer cement-based permeable crystalline high activity waterproof coatingProduct Features

1、 Has extraordinary waterproof ability. Apply two layers of this material on the concrete interface to withstand it1.5MPaThe above water pressure.

2The physical and chemical reactions generated by coating the material on the concrete interface can penetrate into the interior of the concrete, with a penetration depth of up to200mmThe above. And some have the ability to breathe, prevent corrosion, resist aging, and protect steel bars.

3Environmentally friendly, non-toxic, and pollution-free.

4Low temperature resistance:-40℃The5hNo cracking, peeling, or changes.

5Brush the water-insoluble dendritic crystals formed by the material on the concrete interface, compact the gaps, block the permeable water channels, and ensure that they are less than0.4mmThe concrete cracks self repair.

6Can ensure thatPHvalue3.0~11.0, Temperature -30 ℃~ 120℃ The waterproof effect is maintained under certain conditions, and it can protect the steel bars and improve the strength of the concrete.

7Good compatibility with other materials, its waterproof layer surface can be freely coated with materials such as cement mortar, white plaster, paint, resin coating, etc.

8The construction method is simple and labor-saving. No leveling layer is required for the concrete interface, and no protective layer is needed after painting.

Scope of application

Underground railways, basements, concrete pipes, reservoirs, power plants, cooling towers, dams, reinforced concrete boats, tunnels, dock caissons, rooftop squares, parking platforms, elevator pits, sewage treatment plants, swimming pools, nuclear power plants, food storage facilities, sewage tanks, bridge structures, aquariums, fish hatcheries, grain depots, highways, airports, aprons, oil tanks, sports fields, concrete pavements, toilets, etc.
