Viscopaste PB7 Zinc Paste Bandage

For clinicians managing venous leg ulcers, chronic eczema, and other lower-limb skin conditions, Viscopaste PB7 is a familiar name. This zinc paste bandage combines an open-weave cotton fabric impregnated with a soothing zinc oxide paste, delivering the gentle, occlusive skin protection that compression therapy so often requires. The Viscopaste PB7 Zinc Paste Bandage (3 in. x 10 yd., white, ref. 4956) is the standard format kept on hand in wound clinics, community nursing bags, and dermatology practices alike.

The zinc oxide paste helps calm inflamed, weeping, or itchy skin while the moist bandage stays in contact with the limb — a comfort factor that matters for patients wearing these under compression for days at a time. Because the weave is open, the bandage conforms to the contours of the calf and ankle without cutting into the skin, and it's designed to be applied in a pleated technique around the leg rather than stretched, which prevents the tourniquet effect as limb volume changes.

A common question: how long can it stay on? Viscopaste PB7 is typically left in place for up to seven days, then covered with a compression bandage such as a cohesive or short-stretch layer. It is not self-adhesive, so it's almost always used as the base layer of a multi-layer system rather than on its own. Buyers should note that zinc paste products can occasionally sensitize skin over prolonged use, so patient monitoring at each dressing change is good practice.

This paste bandage sits within our broader Wound Care range, where you'll also find complementary compression and dressing supplies for building complete leg-ulcer protocols.
