SFN-D

Technical Datasheet | Supplied by ChenGuang Research Institute of Chemical Industry

SFN-D is a low molecular weight, aqueous dispersion of polytetrafluoroethylene (PTFE) grade by ChenGuang Research Institute of Chemical Industry. Offers spherical shaped particles. Exhibits low viscosity, good flow performance, and excellent penetration. Addition of SFN-D into SFN-1 at 3-5% offer advantages to coatings as enhanced bonding to base substance, thicker layer with each pass of coating, more glossy and void-free surface and greater resistance to wear & corrosion. Recommended for impregnating fabric, porous materials and coating metals by processing methods of dip, coating and spray coating.
