Specifies requirements for two-component coal tar epoxy paints that are primarily applied by spraying for use in protecting iron and steel against atmospheric corrosion.

This Standard specifies requirements for two-component coal tar epoxy paint intended for the protection of iron and steel against corrosion when used on either moist underground or water immersed structures. It is primarily intended for paints applied by spraying (conventional air or airless), which is particularly suitable for high-build coatings. The paint may also be applied by roller, or by brush for small areas.Paint specified in this Standard complies with the provisions of Paint Type 12 given in AS 2312.NOTES:1 When used with the appropriate primer, the paint may be used in systems LP 3-A and LP 3-B given in AS 2312. It may be used as a single coat in system SP-3A.2 The paint is not usually produced in colours other than black or brown. The use of different colours in a two-coat system helps to distinguish between coats and aids application.3 Appendix A provides recommendations on information which should be provided by the purchaser at the time of enquiry or order.4 Additional information on the use and method of application of coal tar epoxy paint is given in Appendix B.5 Alternative means for determining compliance with this Standard are given in Appendix C.
