Mac Dermid <br /> Industrial Solutions <br /> IRIDITE ZDC ACTIVATOR <br /> Surface conditioner for Zinc, Aluminum and <br /> their Alloys <br /> #113076 <br /> Description <br /> Iridite ZDC Activator is a liquid product for the chemical activation of zinc based <br /> alloys before the application of galvanic coatings or conversion coatings <br /> (passivation). <br /> The treatment of these materials with Iridite ZDC Activator improves the <br /> adhesion of the galvanic coatings and the quality of directly applied conversion <br /> coatings. <br /> Iridite ZDC Activator can also be used as a cleaner/activator or activator for <br /> aluminium alloys. It provides a very minimal etch and removes oxides and other <br /> contaminants and provides a surface that is ready to accept the subsequent <br /> conversion coating. <br /> i. APPLICATION <br /> Iridite ZDC Activator is used after the preliminary cleaning of zinc and aluminium <br /> alloys in order to produce the required deoxidation prior to the application of <br /> electrocoating or conversion coatings. <br /> The time of treatment is variable and can be set from seconds to several <br /> minutes. Also, the working bath can be prepared at different concentrations and <br /> /or pH in order to optimize the activity. <br /> Iridite ZDC Activator is primarily used in immersion plants. The inclusion of <br /> Keykote 84 into the working solution will allow for spray cleaning and <br /> deoxidation applications. <br /> All plant structures and fittings must be made of acid resistant materials. <br /> I/I�u��I;{�Ipr,,'1IgI MaDertnW lnc.,245 Freight Slreel,Waterbury OT 06702 .-�. <br /> q W b1 M H-NWN1W Telephone:flog-325-0150 Fax: 203-95-7990 Sales Order Fax: 203-575-5916 ._. <br /> ❑LLSSIIII LLLIII LS IIIJJJJJ❑❑1111 LLLJJJ ww.v.macdermid.com rte, <br />
