Butyl Tapes

Butyl tapes are available as a solid butyl rubber pressure sensitive tape supplied in roll form in a variety of widths and thickness. Tapes are also available with highly compressible PVC foam core encapsulated with high tack butyl adhesive and with butyl rubber adhesive on an aluminum foil backing.

• Offer instant water tight bonds for optimum sealing
• Secure protection when used as a sealant against moisture and dust in appliance
• Help prevent and reduce costly water damage
• Fairly cheap

Applications
Butyl tapes are used for sealing roof-mounted air conditioners, vents, antennas, awnings and window trim. They are useful in sealing storage bins to interior refrigerators and plumbing to exterior seams, for bonding various substrates such as painted metals, aluminum, wood, glass, steel and many plastics and composite materials. Also used for sealing auxiliary spotlights, running and directional lights and for construction of vehicle body and cab including panels, body seams, underbody, roofing, truck beds, trim, wheel wells and exterior electrical harnessing.

Disadvantage
Butyl tapes are not an adhesive and should never be used to install a windshield or any glass that is not mechanically fastened to the vehicle. Butyl is used with foam for various applications. Butyl alone when used for sealing mechanism, when flattened will bounce back into shape forming a leak proof seal every time. Foam core provides a unique compression recovery capability to the butyl tape. Butyl tapes don’t work well under cold weather conditions.
