The first coat of the system must be applied directly to the steel substrate which has been blasted in-situ to a minimum of ISO-SA 2½ freed from rust, scale, water soluble salts and other foreign matter. Application of the systems must be carried out in accordance with the respective product data and system sheets. After application of the full system has been completed, the system has to be cured under specified conditions for at least the minimum period indicated in system and product data sheets.
Exposure of the coating to an aggressive cargo before the coating has obtained full cure, may permanently affect the resistance properties of the system. To obtain maximum resistance in the shortest possible time a hot post cure is recommended.
This list is not valid when shop primers are present under the coating system. Shop primers must be completely removed.
When part of the structure is of stainless steel, the blasting profile of the stainless steel substrate should be the same as for mild steel which is specified in the respective product system sheet.
This resistance list supersedes all earlier issues. The information provided in this resistance list is to the best of our knowledge correct and given in good faith. It is not intended to be exhaustive and the list of cargoes is subject to change without notice. The data is liable to modification, based upon experience and our policy of continued product development. The advice provided, as guidance only, is based upon user reports and laboratory testing that are believed to be reliable.
As many cargoes can be variable in composition and we have no control over the use of our products in service conditions, we accept no responsibility for the performance of the product or any loss or damage whatsoever, arising out of such use.
