The RAL 9002 butyl tape with LDPE lamination is ideal for sealing indoor trapezoidal sheets.
- Very good visual match with the surface.
- Slotted separating paper for quick, reliable application in the corner area.
Compatible with Plexiglas and Macrolon.
- The butyl tape can be used for sealing work in glasshouse and greenhouse construction (tested by Röhm) with no risk of stress cracks forming.
High adhesion to absorbent and non-absorbent surfaces.
- Can be used on all surfaces present in the construction sector, e.g. steel, aluminium, glass, plastic, wood, concrete, masonry, bitumen etc.
- (see usage instructions).
Butyl tapes are self-fusing.
- The tape is fully functional immediately after application and complies with all required properties.
Impervious to vapour diffusion.
- The butyl tape enables waterproof sealing and prevents moisture from penetrating the building.
Applications
- Sealing of dome lights, window frames, trapezoidal sheets, pitched roof glass structures (with press-on profile only), greenhouses, glasshouses and other butt joints made from glass, plastic and metal.
- Sealing of roof passages, rain gutter connections and connections between projecting roofs and masonry.

* Only suitable for indoor applications (3 months' UV resistance)
Application instructions:
- The surfaces to be sealed must be dry, load-bearing and free from grease and dust.
- The application temperature should not be below +10°C.
- We recommend pre-treating absorbent and porous surfaces with Würth butyl primer.
- To obtain good initial adhesion to the surface, the tape should be pressed onto the surface and smoothed using a press-on roller or a similar tool.
- Butyl has a "cold flow" tendency (flow characteristic of the tape). Therefore, the tape should always be fitted with a press-on profile to prevent the seal from slipping, e.g. as a result of the weight of snow or backed-up water. If the tape is fitted or repaired without a press-on profile, there is a risk that the sealing tape may slip.
- When using a press-on profile, the profile manufacturer's specifications regarding the width of the butyl tape must be observed.
- Using excessive contact pressure on the profile will cause the sealing compound to be "pushed out". Never compress the butyl tape to the zero point (use the supplied disc as a spacer)!
- When sealing glass retainer profiles, the rubber profile must not lie on the sealing tape. The width of the butyl tape must be selected such that the tape is located between the rubber profiles.
