Specialty Conversion Coatings

Post Chromate Seals – Asterion has developed a full line of non chrome post treatment seals for expanding the durabiltiy and corrosion resistance of trivalent and non chrome passivates.  These products allow trivalent coatings to meet the corrosion resistance offered by traditional hexavalent chromates.  Available in organic, non organic and nanoparticle formulations, these seals are economical and efficient to use.  All are easily controlled through basic chemical analysis.

High Corrosion Protection Trivalent – Asterion has developed a response to the growing demand for trivalent passivates which compete with the corrosion protection of traditional hexavalent chromates.  This latest generation of trivalent technology provides a thick passivate film to meet or exceed industry standards without the need for a top coat.  Neutral salt spray results of 120 hours to red rust are consistent in production settings.  Cost effective and economical to use, these products perform at lower operating concentrations and lower temperatures than competitive products.

All of these features combine to provide an efficient, simple to use and economical product.  Stability allows for long bath life to further enhance the economy of these products. In response to the concern over the use of cobalt in trivalent coatings, Asterion offers cobalt free formulations with excellent performance and efficiency.
