Novel, Effective, Non-toxic Zinc Free Anticorrosive Pigments for Industrial Maintenance Paints

摘要

Recently developed, innovative family of anticorrosive pigments for paints and coatings is based on Oxy-Amino Phosphate of Magnesia (OAPM) technology, Upon exposure to corrosive environment they form a stable layer of magnesia on the metal surface which protects it from corrosion attack. These pigments, which are non toxic, do not contain chrome, zinc or any other hazardous material, give excellent performance in 2 components epoxy, alkyd, wash primer and water based industrial systems. They meet the requirements for long term anticorrosive protection of both steel and aluminium in industrial maintenance applications, and are especially suitable for DIY (Do It Yourself) paints where the environmentally hazard warning label of zinc compounds can be avoided. The high effectiveness of OAPM pigments enables lower loading in the paint formula than needed with zinc chromate, zinc phosphate and modified zinc phosphates to achieve the desired protection qualities and performance.
