3M™ Dyneon™ Fluoroplastic PFA 6910GZ dispersion is supplied with a pH value of 9 - 11. The viscosity is stable over a wide temperature range which makes the product easy to process. 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. Dyneon PFA 6910GZ can improve substrate adhesion and can increase the corrosion protection and gloss of the coating.
3M™ Dyneon™ Fluoroplastic PFA 6910GZ is mainly used to formulate non-stick coatings for manufacturing cookware and baking tins. The dispersion is mainly used as an additive mixed with PTFE dispersions. It is recommended as an admixture in all layers. As a result of the low particle size, a bimodal particle distribution is created which has a positive effect on corrosion protection due to the increased density. For coating metal surfaces, various techniques such as spray coating, roller coating and silk-screen coating can be employed. Another area of application is the impregnation of metal surfaces, mainly anodised aluminium. Here the nanoparticles in Dyneon PFA 6910GZ are deposited into the pores of the metal which is improving the protection of the metal surface.
