A high cross-linking, two-component, solvent-free acid-resistant primer formulated with organic polymer resin, reactive diluents, and acid-resistant pigments and fillers. It is designed for application over concrete and steel substrates, and is particularly suitable for anti-corrosion and anti-permeation protection of concrete bunds around concentrated sulfuric acid storage tanks, wastewater treatment basins, and as a combined primer and sealing layer for concrete surfaces. It also serves as a corrosion-resistant lining primer for the internal walls of desulfurization chimneys.
