Description

Zinc Methacrylate CAS NO 13189-00-9 is an organometallic compound that serves as a highly effective crosslinking agent and polymer modifier. Its primary value lies in its ability to significantly enhance the mechanical properties, heat resistance, and durability of various polymer matrices. This product is essential for manufacturers in the rubber, plastics, and specialty coatings industries seeking to improve product performance and longevity.

Application

• Rubber Vulcanization & Crosslinking: A key co-agent in peroxide-cured elastomers (e.g., EPDM, NBR) to improve compression set, tensile strength, and heat aging resistance.
• High-Performance Plastics: Used as a reactive monomer or additive to modify properties of engineering plastics and acrylic resins.
• Dental & Medical Polymers: Imparts improved hardness, wear resistance, and dimensional stability to acrylic-based restorative materials and bone cements.
• Adhesives & Sealants: Enhances cohesive strength, adhesion, and thermal stability in structural and specialty adhesive formulations.
• Reinforced Composites: Acts as an interfacial agent to improve bonding between inorganic fillers (like silica, glass) and organic polymer matrices.
• UV-Curable Coatings & Inks: Functions as a multifunctional crosslinker to increase cure speed, hardness, and chemical resistance of the final film.
