Résumé : |
The Calvasol method provides a flexible, economical, and efficient way to functionalize films with corresponding coatings. Compared to alternative methods, the applied layer thicknesses are in the range of 0.1 to 10 nm which reduces the consumption of chemicals and energy in processing. |
Note de contenu : |
- Avoiding high energy consumption for drying
- Treatment and coating in one process step
- Direct integration into the extrusion process
- Further development of functional chemistry
- FIGURES : 1. Schematic representation of the Calvasol method that combines the corona treatment and aerosol application. It is used for the permanent andi-adhesion, antifog or antistatic functionalization of films - 2. The aerosols are applied to the film from below. This has the benefit that the functional molecules can be anchored in a very thin and even layer - 3. The Calvasol system can be integrted directly into the lamination process with no negative influence on the lamination adhesive - 4. Measuring the contact angle of a film coated with and without Calvasol shows the influence of the Calvasol antifog function : The goal is to create a surface with maximum hydrophilic properties, indicated by a small contact angle in the measurement with water. The greater the contact angle (image on the right), the poorer the antifog effect |
