EST-4001 is a non-hardening butyl rubber based sealant,
designed to comply with the current standards and specifications
required by Federal, State, and local regulatory agencies
for use with the precast concrete industry and its contractors.
EST-4001 is designed to remain flexible and will not shrink
or oxidize under long-term aging, and it is resistant to
environmental temperature extremes, acid and alkaline conditions.
An adhesive type seal, it bonds immediately to a clean,
dry surface, including concrete, metal, glass, and most
plastics.

Adhesion and cohesion actually improve after initial bond
has been formed and placed in service, and as such, these
butyl sealants are in common use sealing:
|
- Concrete Foundations
- Burial Vaults
- Pipe Joints
|
- Manhole Joints
- Septic Tanks
- Utility Tanks
