Specification

Highly adhesive, double-sided sealing tape made from butyl rubber for overlapping sealing.

Excellent compatibility with many surfaces

Good compatibility with metals, concrete, masonry, wood, glass, hard PVC, bitumen, paint systems, as well as extremely good adhesive properties, enables a number of combinations in sealing systems.

Good resistance to UV, weather and water

Can be used both indoors and outdoors.

Impervious to vapour diffusion

Self-fusing

Compatible with Plexiglas and Makrolon

The usage instructions are recommendations based on the tests we have conducted and our experience; carry out your own tests before each application. Due to the large number of applications and storage and processing conditions, we do not assume any liability for a specific application result.

We guarantee consistent quality of our products. We reserve the right to make technical changes and further develop products.

Application

For connecting seams and bonding vapour barrier films
Overlapping seals for assembly parts on vehicles and roofs, fau00e7ades and equipment construction, in the furniture and interior design industries, for sanitation and electrical installations and all similar applications

Instructions

Application instructions:

The surfaces being sealed must be dry, sound and free from grease and dust
The processing temperature must not be below +5u00b0C
Pre-treat absorbent and porous surfaces with Wu00fcrth butyl/bitumen primer
Press the butyl tape carefully onto the surface

Pressing the sealing surfaces together results in a perfect seal.

Butyl has a "cold flow" tendency (flow characteristic of the tape)

Butyl products should therefore always be secured mechanically, e.g. screwing the parts, applying a press-on profile.

When using a press-on profile, observe the profile manufacturer's specifications regarding the width of the butyl tape
Using excessive contact pressure on the profile will "squeeze out" the sealing compound. Never compress butyl products absolutely flat (use the supplied disc as a spacer)
