Atotech, global supplier of speciality surface finishing solutions, has introduced UniCoat® CTR, a next generation single step cleaner coater process for multi-metal paint applications.
Based on the same technology as modern zirconium pretreatments, UniCoat® CTR incorporates a robust cleaning package, complementing the zirconium component to achieve efficient cleaning and coating in one process step. Optimised for use in 2 – 4 stage recirculating washer systems, UniCoat CTR offers enhanced cleaning properties, improved pH and process stability, and reduced risk of flash rust during regular production and line stoppages. UniCoat CTR provides applicators with improved paint adhesion and corrosion resistance qualities, closely matching the performance of a traditional alkaline cleaner and zirconium pretreatment process in most applications.
Traditionally, applicators have looked to iron phosphates for their short system pretreatment needs. UniCoat CTR offers applicators a phosphorus-free alternative that significantly reduces the scale and sludge typically associated with phosphate pretreatments. The result is a process that requires less equipment maintenance and a reduced burden on wastewater treatment operations. As part of Atotech’s sustainability initiative, it has also eliminated alkylphenol ethoxylates (APE) from the processes making UniCoat CTR a highly sustainable solution for the surface finishing industry.
UniCoat CTR consists of separate cleaner and zirconium coating additives. The two component process offers a greater level of versatility. Congruently to applicators’ cleaning and coating requirements, the proportion of each component can be adjusted to meet the performance demand.
