Zinc Phosphate Epoxy Primer
Zinc Phosphate Epoxy Primers are available in single-pack and two-component epoxy types, with two-component systems providing higher chemical and mechanical resistance. They are commonly applied on structural steel, pipelines, storage tanks, machinery, offshore components, marine structures, and industrial equipment. Key advantages include strong adhesion to blasted or mechanically cleaned steel, good resistance to moisture and salts, compatibility with epoxy and polyurethane topcoats, and effective corrosion protection without the very high zinc loading of zinc-rich systems. Typical properties include good surface wetting, smooth film formation, high intercoat adhesion, and suitability for C2 to C4 corrosion environments.
Zinc Rich Epoxy Primer
Zinc Rich Epoxy Primers are available in organic (epoxy-based) and inorganic types, with organic epoxy zinc primers being the most widely used in industrial coating systems. They are applied on properly prepared steel surfaces (typically Sa 2½ blasting) and are suitable for steel structures, pipelines, storage tanks, offshore platforms, bridges, refineries, power plants, and marine equipment. Key advantages include excellent corrosion resistance, strong adhesion to steel, compatibility with epoxy, polyurethane, and polysiloxane topcoats, and high resistance to moisture, chemicals, and mechanical stress. Typical properties include high zinc content (often >80% by weight in dry film), fast curing, good weldability, and long service life in C3 to C5 corrosion environments.
Zinc Sulfate
Available in different types—Zinc Sulfate Monohydrate (ZnSO₄·H₂O) and Zinc Sulfate Heptahydrate (ZnSO₄·7H₂O)—it serves multiple sectors. In agriculture, it acts as a crucial micronutrient fertilizer to prevent zinc deficiency in crops, improving yield and quality. In the feed industry, it is used as a dietary supplement for livestock growth and immunity enhancement. Industrially, Zinc Sulfate is used in electroplating, flotation processes, dyeing, and as a raw material for manufacturing pigments and catalysts. Production typically involves controlled reaction of zinc oxide or zinc ash with sulfuric acid, followed by crystallization and drying to achieve the desired purity and particle size.
Zinc Sulfide Concentrate
There are two major types of Zinc Sulfide Concentrate — natural sphalerite concentrate and synthetic ZnS pigment-grade. Each is carefully produced to meet the requirements of different industries such as metallurgy, ceramics, rubber, plastics, and phosphor manufacturing. During production, zinc-bearing ores undergo crushing, grinding, and selective flotation to achieve a high ZnS concentration, typically ranging between 55% and 65%. The product is dried, screened, and tested to ensure consistent particle size and purity. Zinc Sulfide serves as an essential raw material for zinc extraction in smelters, a luminescent material in optical devices, and a pigment base in coatings and ceramics due to its superior whiteness and brightness.
Zink Rich Paint
Zinc can be melted and purified into fine particles of high-purity zinc powder, which is used as the most important anti-rust pigment in anti-rust paint. Zinc-rich paint is widely used in various constructions and is suitable for offshore installations, power plants, petrochemical plants and other aspects. Zinc-rich paints are available in two types , first is organic ,which consist of epoxy resins, chlorinated hydrocarbons and other polymers; and second as inorganic based on organic alkyl silicates.
