1). Description of product:
As a dual component coating solidified at room temperature, the product is composed of epoxy resin, coal tar, modified amine solidifying agent, pigment stuffing, auxiliary and mixing solvent, etc. It possesses the properties of large content of solid, fast solidifying, satisfactory mechanic and insulating properties, as well as excellent anti microbe/plant-root invasion.
2). Designed usage: Be used for the anti-corrosion of above ground or underground pipeline of gas, oil, water and heat supply, it could meet the need of sub-water anti corrosion and insulating for steel/iron, concrete facility, ship, ocean platform and wharf.

4). Instruction for application:
4.1 Application condition: Ambient temperature is above 5℃, the relative humidity of air is not higher than 75%. But work should be stopped when it rains, snows or it's foggy.
4.2 Surface treatment: The steel structure should be shot blasted to Grade Sa2.5. Clear away dust, iron chippings and greasy dirt after surface treatment, then paint in eight hours.
4.3 Applying method: Brush painting manually.
4.4 Treatment of welding seam: The welding seam should be plastered into smooth surface with putty, which is blended with primer, curing agent and appropriated amount of fillings (such as French chalk or mica powder).
4.5 Blending of coating: Mix lacquer with curing agent in proportion of 100 vs. 10~14, fully agitated, aging for 30 minutes before it could be used. The blended coating should be used up in 1~6 hours.
4.6 Repainting interval: The later layer could be applied after surface drying of the first layer, but the interval should never exceed 48 hours. The painting of each layer and wrapping glass-fabric should be done simultaneously; the texture of glass-fabric should be fully filled by coating. And the
last finish should be applied after the full drying of the anti-corrosion layer.
4.7 Recommended painting structure:

Note: The size of glass-fabric is 12 x 12 or 10 x 10, intermediate base, twiddle-free and wax-free.
4.8 Servicing duration: ≥days.
4.9 Thinner: The special thinner of X-02D for the coating is used. The consumption of thinner is about 5 % of coating.
5). Packing, storage and transportation:
Packed and sealed in iron drum, the net weight per drum for component A is 20 kg±0.2 kg, component B is 2 kg ~3 kg (variation of consumption depends on seasons ).
Be stored in shady, cool, dry and well-ventilated place, away from fire and hot resources, and avoid dropping in water. Preventing raining and solarization in transportation, and should be in accord with standards of traffic department.
Upon the base of above condition, the effective storage period is one year from the date of production.
6). Points for attention:
1. Fire is strictly prohibited on job-site, fire fighting tools should be seated at convenient site.
2. Good lighting is needed at job-site. When operation in the equipment, low-voltage power (12 volt) should be employed.
3. When in bad ventilating work-site(such as: in the tank or in basement), efficient ventilating and air exhausting is necessary on the spot. The operator should wear gas mask, and under the protection of special persons.
4. If headache, heart-throb or nausea happens, the operator should leave the work-site immediately, and take rest on well ventilated spot.
7). Product is accord with standards: SY/T0447-96
