UNIDYNE Water & Oil Repellents are used to equip protective face masks and surgical gowns with liquid repellent properties.
Protective masks, simple face masks as well as FFP2 masks or FFP3 masks, often have a 3- or 4-layer structure. The outer layer(s) need to have fluid repellent properties to prevent liquid aerosols, and the bacteria or viruses they may contain, from penetrating the mask. UNIDYNE products can be used to equip PP- and PES-based nonwovens with a fluid repellent finish to make them suitable for use in protective masks.
