Multi-Purpose Tape
Overview:
Multi-Purpose Tape is a high performance sealant tape with superior surface tack that remains elastic and is designed to bond to Sarnafil membranes and a variety of metals. Multi-Purpose Tape is used to seal the
metal roof edge of buildings reducing air infiltration into the roof assembly,
below Edge-Tite metal, behind Sarnafil flashing at termination details and
to seal the overlaps of Sarnavap 10 vapor retarder. Multi-Purpose Tape is
produced in a ¾ in (19 mm) wide x 50 ft (15.2 m) long roll. Multi-Purpose
Tape is 1/8 in (3 mm) thick.
Composition:
Multi-Purpose Tape is a white, high rubber content copolymer tape which
contains isobutylene-isoprene.
Features:
Multi-Purpose Tape is designed to bond to Galvalume®, Kynar 500®,
aluminized steel, Zincalume®, galvanized metal, aluminum, siliconized
polyester and polyvinyl flouride painted metals, glass, wood, concrete,
fiber-reinforced plastics and similar substrates. Multi-Purpose Tape has
high tensile strength and extensibility (webbing/elongation) enabling it to
be used in both hot and cold climates. Its superior surface tack affords
tenacious adhesion to substrates at temperatures as low as -5°F ( -21°C)
while remaining soft and pliable. Multi-Purpose Tape is odor free, formulated without asbestos fillers and contains a special additive which inhibits a
broad spectrum of microbial activity.
Packaging:
Multi-Purpose Tape is available in cases containing 12 rolls. Each roll
weighs approximately 1 lb (0.5 kg).
Installation:
Multi-Purpose Tape is installed by Sika Sarnafil Authorized Applicators to
a clean surface. The surface preparation may include but is not limited to
scraping and wiping free any excessive contaminates on both surfaces the
Multi-Purpose Tape is to be in contact with. Once the surface has been
prepared, apply the Multi-Purpose Tape to the substrate.
Availability:
Multi-Purpose Tape is available directly from Sika Sarnafil Authorized Applicators when used within a Sika Sarnafil Roofing or Waterproofing System.

Will not stain painted or unpainted surfaces.
Will not craze plastics.
At 120°F (49°C) sealant will maintain adhesion to metal surface indefinitely submerged in water.
Sealant will not “cold flow” or in any way lose its shape in relation to bead size or diameter in transit or storage.
Sealant hardness will not increase more than 30% (max.) after aging in QUV test apparatus.
Excellent to water, ozonated water, water vapor,
alsohols; fair to weak for acids and bases. Poor to organic solvents.
