Double Sided Seal Tape

Typical Uses

•Field seaming and repair of polyethylene and polypropylene film/panel.
•Adhesion to concrete walls, galvanized aluminum, plywood, oriented strand board, waferboard, and pink foam insulation sheet.
•Sealing between glass, metal, wood and most plastics.
•Applications that require moisture barrier properties.

Encoat’s ST600 seal tapes are coated on both sides with a thick, aggressive, rubber based adhesive system. The ST600 tapes utilizes a reinforcement engineered to provide conformability and pliability during tape application. These tapes are designed to perform in applications that require very aggressive, non-hardening sealing properties on porous, low energy, cold, and damp surfaces.
