Application

This product is a high performance anticorrosive coating for steel structure, widely used in large indoor and outdoor steel structures.

Such as: pipelines, transmission towers, oil tanks, locks, Bridges, television towers and ships, coastal facilities, oil equipment and so on .

Substrate treatment

Sand blasting or shot blasting should be at least GB8923 88 sa2.5 with roughness of 25-50 microns. The surface of the local repair layer shall be polished to meet GB8923 88 st3.

Construction conditions

Coating temperature range : 5-40℃, relative humidity below 85%, substrate surface temperature above dew point more than 3℃, temperature and humidity should be measured near the substrate.

When the temperature of the substrate is higher than 40℃, it is recommended not to carry out coating construction.

Heavy rain, snow, sand and other bad weather can not be painted.

Packing specification

Group A: 20kg/barrel

Group B: 10kg/barrel

Storage

This product should be stored in a cool, dry, ventilated indoor warehouse, storage period of six months

Note

1 .After sandblasting, the surface is clean and oil-free. Construction shall be carried out within 4 hours.

2. This coating is a two-component coating system, mixing must be in the mixing group B slowly into a group, stirring mixing 15-20mins, enough stirring and curing, through 80-100 purpose sieve filtration rear can be constructed, keep continuous mixing while spraying .

3. Pay attention to adequate ventilation during construction in the storage tank.

4. Coating can be a surface coating, a layer of thin coating must be carried out to prevent a large number of bubbles in the film.

5. Dilute with water, no more than 2%.

6. Stored in ventilated, dry, cool environment, suitable temperature 0℃-40℃. Sealing to prevent direct sunlight, in winter should be heat preservation antifreeze.

7. This coating is water-based coating, non-flammable and non-explosive, still need to pay attention to health. In case of eye contact, flush with fresh water for at least 10 minutes and seek immediate medical attention.
