Tremco Acoustical Curtainwall Sealant Dark Gray 29oz Cartridge
Tremco Acoustical/Curtainwall Sealant is a single-component, non-skinning, non-hardening synthetic rubber sealant intended for use in sound dampening systems. Applied as one or more beads in a joint, it raises the Sound Transmission Class (STC value) of the system and lowers the decibel level that passes through. It does not cure or dry by design: the sealant remains viscous and tacky, which further helps decrease sound transmission. Typical uses are acoustical sealing of drywall partitions, curtainwalls, corridors and party walls. Do not apply it to damp or contaminated surfaces, and use it with adequate ventilation.
Key Features
- One-part synthetic rubber sealant, no mixing
- Non-skinning and non-hardening; remains viscous and tacky

- Passes CGSB tests for sag resistance, extrusion rate, staining and bleeding, and cracking/blistering
- Low temperature flexibility passes at -10 °C (CGSB 11.1)
Applications
- Acoustical sealing of drywall partitions
- Curtainwall joints
- Corridor walls
- Party walls between units

Frequently Asked Questions
What is Acoustical/Curtainwall Sealant used for?
It is intended for sound dampening systems: acoustical sealing of drywall partitions, curtainwalls, corridors and party walls. One or more beads in a joint raise the Sound Transmission Class (STC value) of the system and reduce the decibel level that passes through.
Does it cure, skin over or harden?
No. It does not cure or dry by design. It is a non-skinning, non-hardening formula that remains viscous and tacky, which further helps decrease sound transmission.
What surfaces can it go on?
Do not apply it to damp or contaminated surfaces. Use it with adequate ventilation; the Safety Data Sheet lists mineral spirits and other petroleum ingredients, so read it before use.
What colors and packs are available?
Tremco makes it in Dark Gray only, in 10.1 oz (300 mL) cartridges, 1 quart (850 mL) cartridges and 5 gallon (19 L) pails. This listing is the 1 quart (850 mL) cartridge; the 10.1 oz (300 mL) cartridge is listed separately.
What testing does the data sheet report?
It passes CGSB tests for resistance to sag (7.1), extrusion rate (3.1), loss of mass (5.1), staining and bleeding (9.2), low temperature flexibility at -10 °C (11.1) and cracking/blistering (19.2). Viscosity is 1,000,000 cps and shear modulus 45,000 N/m2.
