Product Name
MBT Butyl Tape2. Product Description
MBT is an elastomeric butyl
rubber-based extruded scalant on silicone release paper, designed for scaling a variety of
construction joints. This product meets the critical requirements of the
pe-engineered metal building, as well as the modular housing and window glazing industries
and is very resistant to ultraviolet light. MBT is engineered to withstand extreme roof
temperatures while offering superior low temperature compressibility and resistance to
cold flow. A wide selection of shapes, sizes and lengths are available to meet most
joint configurations. MBT is packaged in water-resistant cartons suitable for export
shipment.
Composition: Polyisobutylene-isoprene (butyl rubber), inert fillers, tackifying

4.Installation
instructions:
Surface preparation:
All surfaces to be sealed should be free of dust, dirt, oil and moisture before applying
sealant. Clean with soap and water or aliphatic solvent.Working
conditions:
Apply to dry conditions above 400F. Below 400F
atmospheric condensation on surfaces may inhibit adhesion and should be avoided.
Application:
Apply MBT to surface directly from roll. Press
sealant through the silicone release paper with a smooth, even hand motion. NOTE: For metal roofing
and siding applications, be certain to place scalant on the "wet" side of the
fasteners to prevent wind blown rain from leaking through the fasteners holes. |
