Halar Xylan - Fluoropolymers Coating
Fluoropolymers is a collective name for coatings from various different manufacturers. Halar and Xylan are two examples of coatings that we use at Kersten coating technology. The most widely used fluoropolymers are PTFE, FEP, PFA, ECTFE and ETFE. They present excellent non-stick properties, combined with good chemical resistance. They can also withstand high temperatures. In addition, PFA Ruby Red provides increased resistance to vapour diffusion.
Colours and layer thicknesses
As fluoropolymers are diverse, we use a variety of methods for applying them. For wet lacquering in one, two or three-layer systems, the coating is dried after being applied and cured at temperatures between 200 and 400°C. Fluoropolymers in powder form are applied in one or more layers by electrostatic powder coating on a pre-heated surface. The range of colours depends on the type of fluoropolymer.
