Product introduction

Polyurethane waterproof coating is a kind of reactive polymer waterproofing paint. The product is uniform viscous materials.

It is divided into single-component and double-component according to the components. A double-component composed of the component A and the component B, mixes component A and B evenly according to the prescribed ratio on site, after the reaction, the reaction forms a flexible, tough and durable waterproof layer.

Single component does not need extra materials and it can be brushed directly.  High density and high elastic waterproof layer formed after drying.







Advantages

1. Suitable for any complex base surface, coating without joint, perfect waterproof performance.
2. Do not contain coal tar, less irritating odor, environmental friendly.
3. Stable performance, good temperature resistance.
4. Operate easily, fast curing, short working time.
5. High tensile strength, high prolongation and high bonding strength, strong adaptability to the expansion, craze of the base.
6. Single-component coating has the advantage of avoiding the blending the trouble and causing the error.
7. Breaking elongation is excelltn, can reach to 550%, the properties of the breaking elongation is the best one in the existing waterproof coating .
8. Excellent low temperature bending resistance, can reach to 40 degree Celsius , is one of the best in the existing waterproof coating.

Where to use
Roof:concrete flat, sloping roof, roof gutter, awning and all kinds of irregular shape of the roof.ext.
Underground construction:concrete interior wall, external wall, floor, elevator pit, underground tunnel, cable wells, pipe outside waterproof.
Ground construction:toilet, kitchen, Roof garden, reservoir, swimming pool, dressing, bridge etc.
Joint: expansion joint,construction joint, settlement joint, wall pipe, wateroutfall.


Construction technique
1. The basic level requirement: tightness, level, dry, no dust, no pollution, etc. Moisture content is less than 5%.
2. Strengthening of details: Tube root, nozzle, Yang Yin Angle, deformation joint, crack defects are covered with thickness of 1.2 mm of additional layer.
3. Confecting( for double-component): Weight A : Weight B=1:2, pour component A into component B, stir to uniformity.
4. Construction: usually paint more than one time by scraper, rolling brush, the thickness should be uniform, no accumulation, no flow, no leakage brush, paint the second coating perpendicular to the direction of the first coating, coating thickness comply with the design requirements.
5. Construction environment: Temperature>7℃.
6. Protection of coat: before the coating completely curing, it is strictly prohibited to walk on it, pile up sundries, to avoid damaging to the coating layer, cannot carry through store water testing.
7. Protective layer: waterproof coating must be conducted in accordance with the design.


Storage and Delivery sportaion
1. the product should b stored in  dry rooms.
2. Avoid rain, sunshine, collision and fire
3. Storage life shall be within half a year , otherwise, inspection or test is required.


Attention

1. Paint thinner like alcohol acid and nitro can not be used as diluest, avoid contact with water.
2. Good ventilation is required at construction site. Smoke and fire are strictly forbidden.
3. If sediment is found in coating, the coatings need to be stirred evently before application.
4. Good ventilation is required, it can not be used on rainy days
5. Use up the coating within 40mins.
6. Is coating film is found be damaged, use a cutting knife to cut the surroundings of the damaged and then brush and repair it with waterproof coating.
