3M™ Dyneon™ PTFE Dispersion TF 5070GZ is supplied with a pH value of 9 – 11. The dispersion can be mixed with fillers or pigments for use in coating formulations. Dilution is possible at any time but should be carried out with desalinated water.
3M™ Dyneon™ PTFE Dispersion TF 5070GZ is mainly used to formulate non-stick coatings for manufacturing cookware and baking tins. Due to its small particle size, the dispersion is used as an additive to conventional PTFE dispersions so as to achieve a better packing density to the films. These improvements can lead to less corrosion, improved abrasion characteristics and increased shine. For coating metal surfaces, various techniques such as spray coating, roller coating and silk-screen coating can be employed. The formulations have to be adjusted for each technique.
