Kent Seal™ Butyl Sealant

Premium Grade Butyl Rubber Sealant Installs Fast... Any Shape, Any Season

Installs Quickly... Any Season... Works well on virtually any concrete structure or pipe.

Kent Seal™ No 2 Butyl Rubber Joint Sealant is a flexible rope gasketing material ideally suited for fast, efficient sealing of joints in precast concrete products, such as:

  •  Pipes
  •  Manholes
  •  Box Culverts
  •  Septic Tanks
  •  Catch Basins
  •  Utility Boxes
  •  Underground Vaults
  •  Burial Vaults

All Butyl’s are not created equal!

Kent Seal™ No 2 is a premium grade Butyl Rubber compound specifically formulated for the following physical properties:

  • Dense Polymer Structure - resists water vapor permeation through the join t.
  • Highly Compressible - provides superior sealing characteristics to acco mmodate minor imperfections in the mating surfaces.
  • Tacky Outer Surface - its extremely adhesive qualities make it a “nat ural” for those ‘hard to bond to” surfaces.
  • Flexible - provides excellent memory retention to counteract joint move ment and deflection.
  • Temperature Stable - will not go brittle at low temperatures, or spon gy at elevated temperatures. Remains supple and flexible.
  • Aging Resistant - will not shrink, harden or oxidize. Provides extended shelf life.

Kent Seal™ No 2 is supplied in pre-formed coils with an easy-release backing paper. Each coil in the box is separated by an easy-release paper, and a stiffener is placed between each layer for enhanced protection.
