Description
SikaLastomer
-95 Isobutylene
Tripolymer Tape is a high performance,
tacky elastic butyl tape which is designed
to bond through oily GALVALUME
,
KYNAR 500
, aluminized steel,
ZINCALUME
, galvanized metal,
aluminum, siliconized polyester and
polyvinyl fluoride painted metals, glass,
wood, concrete, fiber-reinforced plastics
(FRP) and similar substrates. Its superior
surface tack affords tenacious adhesion
to these substrates without pre-wiping
the surface even at temperatures as low
as 5
o
F. Where superior tensile strength
and extensibility (webbing/elongation)
are critical, in both hot and cold climates,
use SikaLastomer Isobutylene
Tripolymer Tape rather than general
purpose butyl tapes. SikaLastomer is
formulated without asbestos fillers.
SikaLastomer
-95 contains a special
additive which inhibits a broad spectrum
of microbial activity. SikaLastomer
-95
is manufactured in accordance with ISO
9001 / 14001 quality assurance system
and the responsible care program.
Product Benefits
– Resistance to fungus / Mildew growth
– Almost odorless
– Paintable
– Will not stain painted or unpainted
surfaces
Areas of Application
Specifically developed for sealing critical
Standing Seam Roof (SSR) endlaps and
lap joints for metal building roofs,
skylights, roof curbs, smoke vents, air
conditioning equipment, curtain wall
joints and perimeter areas around
windows and doors. Sealing exterior lap
joints of grain storage bins and sealing
the base to the concrete pad. Designed
for sealing polyethylene sheeting and
metal sewer pipes. Sealing exposed,
concealed exterior lap joints of
aluminum, steel, coated metals, wood,
roof rails and door hinges in transport
equipment. Waterproofs rivet seams and
lap seams in truck trailers and RVs.

Excellent for sealing between dissimilar
metals to prevent electrolysis.
This product is suitable for experienced
professional users only. Tests with actual
substrates and conditions have to be
performed to ensure adhesion and
material compatibility.
Chemical Resistance
Excellent resistance to water, water
vapor, ozone and alcohols. Fair to good
resistance to weak acids and bases
(including silage juice). Poor resistance
to aliphatic, aromatic and keytone
solvents and oils. The above information
is offered for general guidance only.
Advice on specific applications will be
