Industrial Applications:
Rubber Industry:
Used as a vulcanization activator, enhancing strength, elasticity, abrasion resistance, and thermal aging in tires, hoses, and rubber components.
Paints and Coatings:
Acts as a white pigment and functional additive, offering UV protection, mildew resistance, and corrosion inhibition in industrial coatings and primers.
Ceramics and Glass:
Functions as a fluxing agent to lower melting temperatures, improve glaze brilliance, and enhance thermal shock resistance in specialty glass and ceramics.
Specialty Chemicals:
Key raw material in the production of zinc phosphate (anti-corrosion), zinc borate (flame retardant), and yellow chrome (pigment applications).
Lubricants and Additives:
Used in manufacturing zinc dialkyldithiophosphate (ZDDP), an essential anti-wear additive in engine oils and industrial lubricants.
Agriculture and Animal Feed:
Serves as a zinc supplement in fertilizers and cattle feed to support healthy plant growth and animal development.
Zinc Dust
Zinc dust is a high-purity, bluish-gray metallic powder recognized for its excellent anti-corrosive and reductive properties. It is widely used in zinc-rich primers and protective coatings to shield steel and other metal surfaces from rust and degradation.
With consistent quality, controlled particle size, and high reactivity, zinc dust plays a vital role in industries such as battery manufacturing, rubber processing, paint formulation, and various chemical applications. Its strong resistance to oxidation and reliable performance make it essential for enhancing durability and preventing corrosion in both structural and chemical environments.
