| Description: SFN-D is a low molecular weight aqueous dispersion of PTFE. In addition to superior properties typical of PTFE dispersions, SFN-D features low viscosity, good flow performance, and excellent penetration. It can be used along, or be added as an aid into other ordinary PTFE aqueous dispersions, such as PTFE Aqueous Dispersion SFN-1 . Adding SFN-D at 3 - 5 % by weight into SFN-1, for instance, can offer such advantages to coatings as enhanced bonding to base substance, thicker layer with each pass of coating, more glossy and void-free surface, greater resistance to wear and corrosion. Applications: SFN-D is usually used as an aid to ordinary PTFE dispersions for the applications of impregnating fabric, porous materials and coating metals by processing methods of dip, coating, and spay coating.
