Zinc Dimethacrylateate Technical 99%

TOPLINK 439 is modified Zinc dimethacrylate,


1. It is mainly used as peroxide bridging agent to increase crosslinking density, increase vulcanization speed, shorten curing time. Heat tearing property and comprehensive physical property is better than that of ZDA.

2, Vulcanized products can obtain salt joint, improve hardness, greatly improve flexural properties, and improve elasticity and wearing resistance.

3, this product has acid resistance, alkali resistance, oil resistance, corrosion resistance, high temperature resistance, but also improve bonding with metal

4, suitable for rubber such as NBR SBRN BRN EPDMU EPM, suitable for golf, cots and industrial rubber products, etc.
