Zinc acrylate

Zinc acrylate (CAS 14643-87-9), also known as zinc diacrylate or ZDA, is a bifunctional monomer used as a crosslinking agent in polymer and elastomer systems.

Where is Zinc acrylate used?

• Rubber compounding: incorporated into peroxide-cured nitrile and EPDM elastomers to increase tensile strength and hardness without additional fillers
• Golf ball cores: crosslinks polybutadiene to deliver energy return
• Coatings and UV-curable systems: reactive diluent and crosslinker improving film hardness and adhesion to metal or plastic substrates
• Adhesives and sealants: rheology modifier and network-forming agent contributing cohesive strength
• It introduces ionic and covalent crosslinks into polymer networks, improving mechanical strength, resilience and heat resistance.

Good to know: Finer grades are preferred for rubber compounding to ensure uniform dispersion. Stabilized grades with inhibitor packages are offered for storage stability during transport.
