Industrial Coatings Applications

Name Active content [wt%] Chemistry

Hydropalat® WE 3500 56 Fluorocarbon-modified polyacrylate

Hydropalat® WE 3370 (Efka® 3570 N) 60 Fluorocarbon-modified polyacrylate

Product A 55 Highly fluoro-modified acrylic copolymer; neutralized by amine

Product B 50 Acrylic resin amine neutralized, fluorinated

Product C 90 Non-ionic polymeric fluorochemical

Remark: concentration calculated active on total formulation

Test Method

Foam behavior Samples stirred for 6 minutes@5000 rpm followed by measurement of weight and volume using a graduated cylinder

Substrate wetting

Assessment 1: Wetting limits Spray application of an increasing film thickness (wedge) on coil coated Al panels, measurement of the lowest film thickness when the substrate is completely wetted Assessment 2: Wetting behavior on pretreated PE-foil Spiral coater application on pretreated PE-foil (solution of a release agent), assessment of wetting defects after film drying

Anti-cratering Post contamination of the formulations with mod. PDMS, spiral coater application on PE-foil, judgment of craters after film drying

Leveling Automatic spray application on coil coated Al panels, dry film thickness at 30-35µm, measurement of w-values as well as LW/SW with wave-scan DOI

Intercoat adhesion Spiral coater application on e-coat panels, curing at relevant temperatures, humidity cabinet for 5 days, after 1d at standard conditions cross-hatch adhesion test
