High Quality Zinc Diacrylate CAS 14643-87-9 for Industrial Use

CapatueTM MCA-633 (Zinc acrylate (ZDA) with CAS number 14643-87-9) is a difunctional solid acrylate salt for use in peroxide cured elastomers(NBR, EPDM, CPE, BR, SRB, Silicone) where enhanced adhesion and dynamic properties are needed. It is an economical way to enhance the performance of peroxide-cured elastomers. CapatueTM MCA-633 (Zinc acrylate (ZDA) with CAS number 14643-87-9) is available at a fraction of the cost of other commonly used agents and yield comparable, even superior, mechanical properties.
Its function is similar to Dymalink® 633 from Cray Valley of Total Company.

Acrylic acid is mainly a copolymer of acidic monomers containing propylene groups, a common synthetic material widely used in coatings, plastics, polymers and rubber. Therefore, acrylic acid is generally considered an organic material.

Crosslinking with peroxide results in the formation of a covalent bond as shown in (A). This carbon-carbon bond is quite rigid and stable and accounts for the lower tensile and tear strength of peroxide cured stocks compared with sulfur vulcanizates. The good heat stability of this covalent bond also explains the superior heat aged characteristics of peroxide cured systems.
In contrast, polysulfide crosslinks formed in sulfur cure are thermally weak but are mobile under stress and can slip along the hydrocarbon chain. This mobility has been used to explain the superior tensile and tear strength in sulfur cured stocks.
