Livestock buildings create an aggressive corrosive environment characterized by:
High temperature: typically 18–39.5°C
High humidity: up to 85% RH
Corrosive gases: ammonia and sulfur compounds generated from animal waste and feed decomposition
Frequent disinfection: exposure to oxidizing and acidic/alkaline chemicals such as hydrogen peroxide, hypochlorous acid, and other disinfectants
These conditions significantly accelerate coating degradation and steel corrosion when conventional coated products are used.
Most standard coated steel sheets use PE-based coatings, which show limited resistance to strong chemical environments:
Acid attack: Acids cause hydrolysis of the coating, leading to softening, swelling, and loss of adhesion
Alkali attack: Alkaline substances trigger substitution reactions in the polymer structure, damaging the coating and reducing protection
Result: Corrosive media penetrate the coating, leading to localized corrosion, coating failure, and reduced service life
Livestock coatings are engineered with specialized resin systems featuring:
High cross-link density for enhanced structural stability
Fluorine-containing additives, forming strong C–F bonds with high bond energy
Superior chemical resistance to acids, alkalis, disinfectants, and corrosive gases
This formulation significantly improves resistance to chemical erosion compared with conventional coatings.
