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.
Safety data sheet must be read and understood before use.
- 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 watertight and airtight also.
