Asconium® 500 - Easy to introduce water-based corrosion inhibition and adhesion promotion

Asconium® long-term corrosion inhibitors have always delivered significant advantages over inorganic inhibitors. With no milling required, Asconium® grades are easier to incorporate into formulations and offer better gloss retention, fewer labelling requirements and improved performance for both salt spray and anti-blistering. They have also been widely adopted in the most modern water-based direct-to-metal primer applications. However, to achieve the best Asconium® performance, there have historically been certain procedures to follow in terms of order of addition and possibly pre-neutralisation.

To enhance the ease of use of Asconium® inhibitors, ASCOTEC have developed Asconium® 500 which delivers the coatings formulator several advantages:

• Asconium® 500 can be added at any time during manufacture, even post-addition without loss of performance
• VOC free
• Wide compatibility with most commercially available water-based polymers
• Low dosage
• Up to C5 corrosion class performance depending on the binder and formulation

Ascotec have conducted extensive studies using polymers from the most prominent resin manufacturers which have confirmed the performance of Asconium® 500 and its near-universal compatibility in water-based acrylic resins, water-based alkyd polymers and water-based epoxy resins and a good number of validated starting point formulations are already available.
