Surface Tolerant Epoxy Coatings are specially formulated high-performance coatings designed to be applied on minimally prepared or marginally cleaned metal surfaces. These coatings provide excellent adhesion and corrosion protection even on surfaces with existing rust, old coatings, or imperfect surface preparation. Surface tolerant epoxy coatings are widely used for maintenance painting, rehabilitation projects, pipelines, storage tanks, offshore structures, power plants, and industrial steel structures where abrasive blasting is difficult or not possible.
