illbruckmaking it perfect. Description ME407 is a membrane made up of a laminate film with a pure butyl adhesive layer, lined with siliconised paper. Colour Black film, black butyl (grey also available) Roll Width (mm) Roll Thickness (mm) Butyl Tape NT Preparation • Bonding surfaces must be stable, clean, and free from grease and other contaminants that could affect a sound bond. • On highly porous substrates (concrete, cellular concrete, plasterwork, etc.) as well as butyl tape overlaps, we advise priming with ME901 or ME902 Butyl & Bitumen Primer. Usage / Purpose ME407 is a cold applied, self-adhesive membrane for vapour, air and watertight joints between exterior wall sections and load-bearing structures. Used to make various joints and exterior wall sections internally vapour and airtight, externally water tight, and to create pressure equalisation in the exterior wall structure. Ideal for sealing transom/mullion capping joints in curtain walling. Key Benefits • UV resistant film/backing • The adhesive layer remains flexible at high and extremely low temperatures and does not extrude • Does not cause staining on the substrate, so the adhesive layer does not dry out • Bonds to virtually all existing substrates • Does not require preheating before or during application • Provides permanent grip • Very high vapour tightness, hence water tight and airtight

Butyl Tape NT illbruck making it perfect. • To determine the width dimension of the illbruck ME407 Butyl Tape NT, the following general rule applies: the width of the joint plus 100 mm bonding surface (50 mm either side). • An overlap of 50 mm should be provided when joining two lengths of ME407 together. Health & Safety Precautions Safety data sheet must be read and understood before use.
