Description: SikaLastomer Isobutylene Tripolymer Tape is a high performance, tack elastic butyl tape which is designed to bond through oily Galvalume, KYNAR 500,aluminized steel, ZINCALUME, galvanized metal, aluminum, siliconized polyester and polyvinyl flouride 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° 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.

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.

Chemical Resistance: Excellent to water, water vapor, ozone and alchols. Fair to good resistance to weak acids and bases (including silage juice). Poor resistance to aliphatic, aromatic and keytone solvents and oils.
