ASCONIUM®

Product Overview

ASCONIUM® liquid anti-corrosion additives are comprised of a blend of organic molecules that offer long-term anodic protection to multiple metal substrates. They can be formulated into either solvent- or aqueous-based coatings and work well in both pigmented and clear systems.

Anti-corrosion pigments, such as zinc phosphate, are a well-established class of anti-corrosion additives used in the coating industry. Their usage presents several problems however: it is difficult to achieve high gloss finishes, they are often based on heavy metals (requiring labelling) and they can be difficult to stabilise. ASCONIUM® overcomes these problems with products that are easier to incorporate and stabilise, whilst being effective at much lower dosages than traditional mineral pigments. Additionally, they offer enhanced adhesion and blistering protection, improved water resistance and a strong chemical barrier effect.

They can be used on their own or in synergy with mineral pigments and organic/hybrid additives. Typically this will be in situations where both cathodic and anodic protection is required.
