Usage / Purpose ME480 has been specifically designed for construction applications where high fire retardent performance is required (e.g. tall buildings - Relevant Buildings >18 m high). Provides permanent watertightness, air tightness, compartmentalization and for repairs of vapour-impermeable joints and seals in construction applications. Bonds with most normal building materials such as glass, steel, concrete, stone, wood and aluminium. Key Benefits • Reaction to fire - EN13501-1: Class B-s1, d0 (Complies with ADB requirements) • Both the aluminium foil and the butyl adhesive layer are UV-resistant • Adhesive layer remains flexible at high and extremely low temperatures • Non-staining • Adhesive layer does not dry out • Bonds to virtually all common substrates • Very high vapour resistance, including water and airtightness

Butyl Tape BB illbruck making it perfect. • To determine the width of ME480 for covering joints, the general rule is to allow the width of the joint plus 50 mm cover onto both sides of the joint. • For membrane overlap joints, allow a minimum of 25 mm cover. Application • When applying ME901, allow approximately 30 minutes to dry before commencing application of ME480. • When applying more than one layer, start at the bottom and overlap any additional layers to provide water run-off. For window perimeter sealing, apply the sill membrane first, then the two sides and finally at the head. • Attach...
