Introduction
What Are Heavy-Duty Coatings?
Heavy-duty coatings are specialized protective coatings designed for long-term service in harsh corrosive environments, including exposure to acids, alkalis, salts, and aggressive chemical atmospheres. The dry film thickness (DFT) typically exceeds 200 µm; in marine environments, corrosion protection lifetime can reach 10–15 years.
Key Characteristics
1. Long-Term Corrosion ProtectionService life of 10–15 years or longer in chemical and marine atmospheres. Even under acidic, alkaline, saline, or solvent media at elevated temperatures, effective protection can exceed 5 years.2. Thick-Film ApplicationConventional coatings run ~100–150 µm DFT; heavy-duty systems run 200–300 µm or more. Some applications reach 500–1000 µm, up to 2000 µm in extreme cases, for stronger barrier and chemical resistance.
Technical Characteristics
Heavy-duty coating technology involves:
• Synthesis of corrosion-resistant resins
• Application of high-efficiency dispersants and rheology modifiers
• Development of anti-permeation and barrier pigments
• Application control and coating performance monitoring
