Zinc Octoate
Zinc Octoate is a metal carboxylate solution containing approximately 10% zinc content, derived from zinc and 2-ethylhexanoic acid (octoic acid). It functions as an effective curing agent, catalyst, and crosslinker in various polymer systems such as paints, coatings, adhesives, and rubber compounds. This compound improves film hardness, drying times, and overall durability of finished products, making it widely used in industrial and manufacturing processes.
