1 CHEMICAL RESISTANCE TABLES Version: ADD Resins and Chemicals (Pty) Ltd Distribute a comprehensive range of unsaturated polyester resins for chemical resistance applications. The resins recommended for chemical resistance are 1. - General Purpose orthophthalic based resins 2. B DCPD based resin Isophthalic acid based resin with good chemical LAMINATING RESINS: ORTHO SERIES DCPD SERIES ISO SERIES resistance properties B011- The chemical resistance table shows the maximum working temperatures to which the chemical resistance laminates should be exposed. The side of the laminate exposed to the chemical environment should always be a resin rich layer reinforced with synthetic tissue. The data has been determined from a number of sources including case histories, laboratory tests and practical experience. It is emphasised, however, that this information is only intended to serve as a guide to the resistance of fully cured laminates. It should be pointed out that the reinforcement type, fabrication technique, laminate quality, design, exposure conditions, loadings both static and dynamic, all play their part in environmental resistance. Laminates must be post cured in order to develop their maximum chemical resistance and heat deflection temperature. Mouldings should be allowed to stand for at least 24 hours then post cured for minimum of 3 hours at 80 C. If operating temperature of the article is to be above 80 C then the post cure temperature must be at the operating temperature. To the best of our knowledge, these are reliable but made without any representation of guarantee or warranty of accuracy and are made with reservation of all patent rights. Our products are sold on condition that the users themselves carry out their own tests to determine the applicability of the information and suitability of our resins for their particular requirements Page 1 of 7
