Zinc dimethacrylate is an unsaturated hydroxy acid salt that polymerizes in peroxides and cadmium-magnesium vulcanization systems and is partially grafted onto rubber molecular chains to produce a large number of salt-bonded cross-links, thereby greatly improving the degree of cross-linking of vulcanizates. Modified Zinc Dimethacrylate improves its dispersion in the rubber compound and reduces the risk of scorch. Toplink® 439 is Modified Zinc Dimethacrylate , a difunctional solid dimethacrylate for general applications requiring enhanced adhesion and scorch retarding. Toplink® 439 is recommended for use in peroxide cured systems for coatings and formulations requiring enhanced adhesion. ADVANTAGE: 1. Contains non-nitroso inhibitor package for scorch resistance 2. High crosslink density 3. Fast cure response 4. Improves metal adhesion 5. increasing hot tear strength 6. Better elongation, high tear strength, higher tensile strength...
Low Zinc Activator Topfine® CR510 BACKGROUND European Commission has confirmed the EU-wide ban on the use of zinc oxide at medicinal levels in piglet feed in 2017, EU 2017/1413 Regulation made further limit on zinc oxide in cosmetics, in 2016, California Senate Bill 1260 even tried to ban the sale of motor vehicle tires in California that contained more than a certain amount of zinc by weight. To follow this tread, we have developed Low-Zinc Activator Topfine® CR510, it has t he characteristics of low zinc content, high vulcanization activity and excellent dispersion. Zinc content is only half of common Zinc Oxide (ZnO), which is environmentally friendly, and meets the requirements of rubber products performance. Activator Topfine® CR510 is prepared by means of liquid phase reaction, which is obtained by reaction under specific temperature and PH conditions, also obtained under dehydration process and granulation technology. PRODUCT HIGHLIGHTS ● High activati...
