Generation of durable easy-to-clean coatings on foils

A novel and durable easy-to-clean coating based on a UV-curable clearcoat with incorporated SiO2 particles and a thin functional polymer coating based on a zwitterionic phosphorylcholine was developed recently.

The cleaning of decorative surfaces, e.g., on furniture or in automotive industry, is a time-consuming process with high maintenance costs that partly requires special cleaning chemicals as well as a laborious manual effort. Source: 4th Life Photography –

The coating can be applied on PVC foils as well as PET foils and subsequently transferred to different decorative surfaces, e.g., via lamination or bonding. The developed three-step application process consists of a lacquering step with UV curing, a plasma surface modification, and the deposition of a thin functional polymer layer.

Removal of oil impurities with pure water

It can be easily integrated in industrial printing or roll-to-roll processes, which are normally used for foil functionalisation. With the presented coating, it is possible to remove oil impurities from the functionalised foil by pure water without the necessity of cleaning surfactants. Furthermore, the thermal, chemical, and mechanical durability of the coating will be discussed.

The study is published in: Journal of Coatings Technology and Research, November 2019, Volume 16, Issue 6, pp 1515–1525.

EC Tech Report Functional Coatings

A deep dive into major innovations in the field of FUNCTIONAL COATINGS!

The requirements imposed on modern coatings systems have increased significantly over the past decade, and you are certainly familiar with effects such as easy-to-clean, soft feel, and self-healing. However, these effects, too, can be developed even further, thanks to newly modified polymers, multifunctional additives, and nano-structures.

Dive into this new multimedia EC Tech Report and learn more about super-hydrophobic finishes that offer special easy-to-clean effects in clouding an antimicrobial effect; multifunctional additives that regulate several paint properties all at once, and further key innovations that have occurred in functional coatings over the last two years!
