Epoxy Coal Tar
Product Function
Epoxy Coal Tar is a major development in protective coatings, 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 coat being 5 to 10 times as thick as normal paint coatings. In addition, it may be applied in almost any conditions under which is reasonable for men to work and attains its superior properties even when immersed in water or sea-water soon after its application. In practice Epoxy Coal Tar is designed as a heavy duty anti-corrsive 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 coating of approx 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 the performance. Epoxy Coal Tar will however, tolerate less thorough preparation than many materials. Minimum preparation is removal of loose rust and millscale and degreasing. Epoxy Coal Tar can normally be applied direct to the steel or other surfaces. A special primer may be required in certain cases and Acron will be glad to advise on receipt of details.
Application
Epoxy Coal Tar is ready for use immediately after mixing. Apply by brushing as with ordinary paint. When mixed Epoxy Coal Tar does not normally need thinning before use, however universal thinners may be added if necessary but because of the viscous nature of the material, it will take some time to mix in. When ordering Epoxy Coal Tar remember to order sufficient cleaning thinners. Ordinary thinners are not satisfactory for cleaning brushes or spray equipment.
Chemical Resistance
Epoxy Coal Tar has outstanding resistance to water, sea-water and brine solutions. It has first-class resistance to alkalies, acids and detergents and also stands up to petrol (gasoline), diesel fuels, petroleum solvents, oils, fats and greases.
Mixing Ratio
Epoxy Coal Tar is a two pack material. The base and hardener are supplied in correctly matched quantities, no measuring is needed if the whole contents of the can are to be used up at any one time - simply pour the contents of the hardener can into the can containing the base resin and stir thoroughly. If a small quantity is required, the proportions for mixing are 3 parts of the base resin to 1 part of the hardener by volume.

Health and Safety
When dealing with the application of liquid material, it must be noted that Epoxy Coal Tar has a flashpoint of 25°C (79°F) and should only be used away from possible sources of ignition. Skin contact must be avoided and attention must be given to industrial hygiene, extraction of vapours and fire precautions. Personnel should be informed of any handling requirements
