Product description
tesa® 64801 is a double sided closed-cell PVC foam tape with an acrylic adhesive on both sides. The closed cell foam can create a waterproof barrier when compressed, while still being flexible enough to seal uneven surfaces. The higher density foam of tesa® 648 Series foam tapes has a great resistance to water penetration, making it the ideal choice for sealing applications in the glazing market. The product is available in customized die cuts.
