Sealing tape butyl

Butyl sealing tape is a permanently self-adhesive, self-bonding tape that seals joints, overlaps, and fixings. Würth’s butyl rubber tape gives a long-lasting seal, thanks to its UV, weathering, and ageing resistance. It adheres well to most common materials. Typical uses include sealing overlapping side walls on camper vans, caravans, and HGVs, with trim strips crimped on, and sealing standing seams. It also mounts plastic attachments and panelling, such as indicators and lights, that are built in or screwed on. Depending on the design, it can help seal service hatches against oily or salty spray water. Choosing a tape that suits the material and the joint is crucial for a seal that lasts.
