High-Performance Anti-Corrosion Solutions for Heavy Industry

GTC has long been dedicated to the research and development of high-quality zinc pigments, supplying reliable anti-corrosion materials to major domestic and international coating manufacturers. Through continuous innovation, strict quality control, and standardized production management, GTC delivers zinc pigments that meet the demanding requirements of heavy industry and infrastructure applications.

Zinc pigments are a critical component of anti-corrosion coatings, with more than 50% of anti-rust paint formulations consisting of zinc-based materials. GTC’s zinc products are trusted by leading paint manufacturers for both internal and external corrosion protection systems.

Product Applications

GTC zinc pigments are widely used as essential ingredients in anti-corrosion coatings for:

  • Shipbuilding and offshore structures
  • Heavy industry and industrial facilities
  • Automotive components
  • Steel manufacturing and steel processing plants
  • Construction and infrastructure projects
  • Steel-related industries requiring long-term corrosion protection

These applications demand consistent quality, stable performance, and proven corrosion resistance—standards that GTC zinc pigments are engineered to meet.

Particle Size Range
Lead Content Packaging Options

Zinc dust is primarily used in corrosion-resistant coatings for steel structures where long-term durability is essential.

Zinc Flake

Advanced Anti-Corrosion Pigment with Enhanced Coating Performance

Zinc flake pigments offer a next-generation solution for anti-corrosion coatings, delivering superior protection with optimized material efficiency.

Structural Advantage

Due to their lamellar (flake-shaped) structure, zinc flakes provide:

  • Significantly higher specific surface area than spherical zinc dust
  • Lower pigment volume concentration in formulations
  • Higher binder content, resulting in improved coating performance
  • Reduced zinc content in paint while maintaining corrosion resistance
  • Improved edge and corner protection
  • No blistering during service life
  • Smooth and uniform surface finish
  • Lower coating weight
  • Greater coating flexibility
  • Enhanced adhesion to substrates
  • Excellent overcoatability
  • Low porosity and permeability
  • Metallic appearance
  • Minimal sedimentation
  • Easily re-stirrable pigments during storage

Advantages of Zinc Flake Coatings

These properties make zinc flake coatings particularly suitable for high-performance and long-life anti-corrosion systems.

Packaging Options

  • 25 kg PP bag
  • 20 ~ 40 kg pail can
  • 500 kg PP bag

Quality Control & Testing

GTC operates under a standardized operation and material control system, ensuring:

  • Consistent particle morphology and purity
  • Reliable batch-to-batch quality
  • Comprehensive test reports for customer verification
  • Efficient professional technical support

This systematic quality management allows customers to integrate GTC zinc pigments seamlessly into their coating formulations.
