These resin chemists aren't talking. They're typical of many chemists who now use Du Pont TYZOR® organic titanates as polymerization catalysts with various resins. The results are so exceptional that the precise processes are often kept secret. TYZOR organic titanates are a series of twelve titanium esters. They range from very reactive to stabilized chelated forms. Despite the hush of secrecy that often conceals their exact use, one fact is clear. The titanates are revolutionizing certain aspects of resin chemistry. Why? For a host of reasons. At relatively low temperatures, TYZOR organic titanates provide faster cures than you'll get with conventional resin catalysts. Moreover, unwanted side effects are sharply reduced. Predictability is greatly increased. And the titanates actually improve the resins. They in crease hardness. Beef up solvent resis tance. Strengthen electrical properties. Can they help you? Frankly, we can't answer this question. Because we don't know the projects you may be working on. But, in general terms, TYZOR organic titanates have proved to be unusually effective polymerization catalysts in key areas like these: Epoxy resins. The titanates provide faster curing times, longer pot life—and better physical properties in the bargain. Polyester and alkyd resins. The titanates are very suc
cessful in catalyzing direct esterification and transesterification types of reactions. Silicone resins. Here the titanates are valuable catalysts in the production of silicones. Often help in cross-linking silicones, too. Polycarbonate resins. The titanates are particularly use ful in producing polycarbonate resins of high molecular weight. Polylactone resins. The t i t a nates provide swift, low-temperature polymerization of lactones. Polylactones are valuable because they react with diisocyanates to yield high-per formance urethane resins. And what about olefin polymer ization? Phenol-formaldehyde resins? Carboxylic acid methylamides ? Cellu lar polyurethanes? Hydroxy crosslinking? . . . In all these areas, the titanates have offered significant ad vantages. Resins aren't the whole story. The titanates are making chemical history with other products. They can pro foundly alter the surface character of solid materials. To name just one example, they impart scratch resistance to glass.
