Key Benefits
  • Sealing Power: Creates a locked-out barrier against water, air, and moisture. Say goodbye to leaks and corrosion at the joints of your metal structures.
  • Superior Adhesion: Provides robust adhesion strength to a varlety of metal surfaces, ensuring a secure and long-lasting bond.
  • All-Weather Reliability: Built to withstand the harshest weather conditions, our Butyl Tape maintains its flexbility and sealing properties in extreme temperatures, high and low.
  • Low VOC: Free from harmful chemicals.

Applications & Uses

Compatible Substrates & Surfaces
Limitations
  • Do not apply to damp, frosty or contaminated surfaces.
  • Confirm adhesion with intended substrates prior to application
  • Not for structural bonding. Requires mechanical fastening or stabilized joints to prevent substrate movement.
Application

Surface preparation: All surfaces to be sealed should be free of dust, dirt, oil and moisture before applying sealant.
Working conditions: For best results, apply in dry conditions above 40ºF.
Application: Apply PEB-360 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, place sealant under the fastener to prevent wind-blown rain from leaking through the fastener holes.
