Product Description

Coal tar epoxy coating

I. Overview:
　　 The paint is divided into two sets, A made up of epoxy resin, coal tar and colorant and B curing agent. The paint has not only an excellent feature of water resistance and very good adhesive force but also good rigidity, wear resistant and especially prominent three proofings. The paint can be used on seaport facilities, shipping, bridge beams, offshore oil extraction equipment, mining and hydro-power facilities. It can be directly spread on the surface of iron or steel or be blended with priming paint.

IV. Construction Precautions:

1、 Construction should be carried out with good ventilation and safeguard measure should be taken if longtime construction is carried on.
2、 Open flames are prohibited on construction site.
3、 Manual construction should be avoided if the surface temperature of iron or steel is 3 ℃ over dew point.
4、 No construction should be carried out when it is foggy, rainy or snowy or the humidity is over 85%.
5、 The construction temperature should be over 10 ℃ .
V. Storage and Transportation:
Avoid collision while conveying. Store where it is cool and ventilative. The storage period is one year. Expired products can still be used if they pass the standard test. Moisture penetration and exposure to sunlight are strictly forbidden.
