As regulatory pressure continues to increase on the use of PFAS, coating manufacturers are looking for additives that offer alternatives to polytetrafluoroethylene (PTFE). The good news is that newly developed additives for waxes and dispersions demonstrate strong possibilities for use in high-performance can and coil coatings. PTFE is a common fluoropolymer used in a variety of industries because of the desirable properties it imparts. Properties like exceptional che-mical resistance, low coefficient of friction, good resistance to heat and low temperature, and enhanced surface durability make PTFE particularly useful in the coatings industry for applications such as metal packaging and coils. The PTFE particles create a micro-surface texture that promotes these sought-after properties, which is often termed the “overlay or ball bearing” effect.
