Thin film technologies
Completely new thin film technology — Pronortec
Thin film technologies in brief
Thin film technologies are also called nano- or conversion technologies (treatments/coatings), depending on the actors involved. The reaction between the chemical solution and the metal forms a nanoscale surface that improves paint adhesion and corrosion resistance. Traditional thin film technologies are based on the use of either zirconium, titanium or silane. The zirconium coating provides better corrosion protection and the silane coating is better for paint adhesion. Therefore, combining the best possible corrosion protection and paint adhesion in the same product has been a challenge for these technologies.
The number of pre-treatment steps used in production and the quality of the water also have a major impact on the final result: A three-to-five-step solution achieves a quality level equivalent to iron phosphating, whereas higher quality levels require more steps and/or the use of purified water.

Chemtec thin film technologies
Our principal has invested in solving the challenges of traditional thin film technologies. In 2020, a completely new thin film technology called Pronortec, based on organic phosphorus, was launched. As a result of product development, the technology combines the best corrosion protection and paint adhesion properties in one product, which has previously been a challenge with traditional thin film technologies. The five-step pre-treatment process achieves a higher level of quality than traditional thin film solutions.
Our principal’s Chemtec product portfolio also includes zirconium (PASS NC2) and silane (Orgasil) based products. All these products have an emphasis on environmental friendliness and represent traditional passivating and thin film technologies that have been on the market for many years.
