Applications & Uses

Application Instructions

• All surfaces must be clean and dry.
• Apply with a standard caulking gun.
• Cut nozzle to desired bead size. Puncture inner seal.
• Apply at a 45° angle using constant pressure.
• Use at room temperature for ease of gunning.
• Use mineral spirits or VM&P Naphtha to remove excess material.

Basic Use

• Acoustical Sealant - Reduces sound transmission of partition systems. It will effectively increase the Sound Transmission Class (STC) value by as much as 65% by properly sealing partition openings. See ASTM C 919-02 Section 8.2.2 for use of non-drying and non-skinning sealants in acoustical applications.
• Roof Panel Rib Sealant - A good balance of cohesion and adhesion to painted and aluminized steel panels as manufactured on a roll forming machine without further cleaning, pretreatment or other surface preparation at erection temperatures from -7°C to 60°C (20°F to 140°F).
• Vapor Barrier Sealant - Maintains a positive airtight seal by remaining both permanently adhesive and flexible to all substrates that it is applied onto, such as polyethylene vapor barrier films, wood, concrete, metal and foam boards. It is excellent for sealing roof drains and behind termination bar details for commercial roofing applications
• Bedding Sealant - Used as a buck frame, threshold or bedding sealant when applied to metal or glass surfaces.
• Curtainwall Sealant -  Prevents air infiltration and water leakage to unexposed curtain wall joints.

Clean Up

Clean with VM&P Naphtha or Mineral Spirits.

Limitations

• All surfaces to be sealed or bonded must be clean and dry.
• Not recommended for direct contact with IG (Insulated Glass) Sealants.
