Zinc Oxide
Product Overview: Zinc Oxide
Zinc Oxide (ZnO) is a versatile, high-purity inorganic compound combining fine particle size and exceptional chemical stability. It functions as a multifunctional additive and activator across rubber, coatings, adhesives, sealants, and ceramic systems.
In rubber compounds, it serves as an activator in vulcanisation and contributes significantly to mechanical and thermal performance, while in coatings it supports corrosion inhibition, UV protection, mildew resistance, and gloss retention. Its surface activity and controlled particle characteristics also help improve adhesion, formulation consistency, and intercoat bonding.
Key Benefits
Vulcanisation Activation
Supports efficient curing and cross-linking in rubber compounds, improving elasticity and wear.
Corrosion Inhibition
Helps protect coated metallic surfaces from moisture, oxidation, and chemical degradation.
UV Protection
Supports resistance to ultraviolet exposure, preserving color and binder integrity outdoors.
Improved Adhesion
Enhances bonding, substrate adhesion, and intercoat performance across primers and topcoats.
Thermal Stability
Contributes to heat-resistant formulations and aids in dissipation of dynamic heat buildup.
Mildew Resistance
Helps improve durability and microbial resistance in suitable architectural and industrial coating systems.
