Corrosion protection coating Corr series

wear-resistantprotectivehydro-oleophobic

Overview
HEGGEL® Corr is a family of novel, high-performance protective coatings combining organic and inorganic molecular structures to deliver thermal stability, a highly crosslinked impermeable matrix, exceptional chemical resistance and strong mechanical abrasion resistance. The HEGGEL Corr range includes spray-grade, semi-paste and paste grades as well as specialty laminating and sealer systems. Many systems cure at ambient temperature as a single coat (self-priming) and can be applied by airless spray, brush or roller.

Key general properties

• Hybrid organic/inorganic chemistry delivering thermally stable, highly crosslinked coatings
• Solvent-free formulations in many variants; single-coat, self-priming ambient cure in multiple products
• Excellent resistance to concentrated and diluted acids, alkalis and a broad spectrum of chemicals (pH 1–14 in selected grades)
• High fouling resistance and smooth finishes to improve fluid flow and reduce sludge build-up
• Good sliding abrasion resistance and strong adhesion to steel and concrete (varies by product)
• Applicable to moist substrates in selected grades; some products suitable for in-situ application on hot or operational equipment
