Product Description



Other waterproofing material polyurethane waterproof coating for railway and bridge construction

1. Product introduction

Railway and bridge used in (high iron special) polyurethane waterproof coating belongs to the double group chemical reaction type waterproof coating, wherein the first group is obtained by polyether polyol and isocyanate condensation of isocyanate terminated prepolymer, group B is by strengthening agent, plasticizer, thickening agent, coagulant composition of the colored liquid. Use would be a, B two groups according to the mixing ratio, brushing in the waterproof base, often temperature curing, forming high strength and high elongation of rubber like elastic coating

2. Advantages

High strength, can be as high as 6.0MPa; good extension performance, up to more than 450%; low temperature performance

This product can be thick coating, coating density, complete elastic waterproof layer without bubble formation of continuous seamless

Cold construction, Party A and Party B can be fully mixed in proportion to the construction, easy to operate.

The chemical reaction film, water resistance, corrosion resistance, low temperature resistance, no mildew, strong permeability

3. Application Range

High speed railway, viaduct, expressway, underground engineering, municipal engineering, water tank, dam and other waterproof, moisture proof engineering.

4. Key points of construction

The basic requirements of rugged, flat, no debris, fully dry

According to the proportion of the ingredients to be a B two groups according to the proportion of the mixture, and with an electric stir bar, the node parts according to the requirements to do additional processing

The construction adopts scraping or spraying, the thickness is uniform and uniform. Thickness in 1.5mm-2.5mm should 3-4 times, after coating should be carried out after the completion of the previous film curing, brushing or spraying direction and to the previous perpendicular to each other.

After the acceptance of the film, according to the design requirements to protect the construction of isolation layer

5. Matters need attention

Limit the use in the snow, sand, cold weather

Group B if there is a precipitation phenomenon, does not affect the quality of products, should be used to stir again according to the proportion and the mixing.

Construction site is strictly prohibited fireworks

The construction of protective layer should be carried out in time after the coating is finished.
