General

Epoxy Coal Tar is a protective coating designed to resist chemical attack and rigorous weather conditions by combining the outstanding properties of epoxy with those of coal tar. Thick coatings can be built up with minimum labour costs, each being 5 to 10 times as thick as normal paint finishes. In addition, it may be applied in almost any condition under which it is reasonable for men to work. It attains its superior properties even when immersed in water and sea water soon after application. In practice, Epoxy Coal Tar has been found to cure at temperatures as low as O°C. It is designed as a heavy duty anti-corrosive and protective coating for iron and steel, non-ferrous metals and for other types of constructional materials such as concrete, bricks, timber etc. The material is black in colour and gives a dry film coating of over 125 microns (0.005") in a single application. It is designed as a brushing material but may be sprayed with airless equipment. Epoxy Coal Tar is easy to use, contains little solvent and dries quickly.

Surface Preparation

The more thorough the preparation, the better Epoxy Coal Tar will perform, however it will tolerate less preparation than many materials. Remove all loose rust and millscale and degrease the surface. The Epoxy Coal Tar can then be applied directly to the surface. A special primer may be required in certain cases and we will be glad to advise you as to the most suitable product on receipt of details.

Application

The product is ready for use immediately after mixing. Apply by brushing as with ordinary paint. It does not normally need thinning before use. If thinners are used, they will take some time to mix in due to the viscous nature of this paint. When ordering, remember or order sufficient brush cleaning Thinners. Ordinary thinners will not be satisfactory for cleaning brushes or equipment.

Epoxy Coal Tar conforms to BS5493 parts KF3A/B.
