Description

AC-20 FTR 5 gallon is a unique acrylic latex sealant that is UL Classified in firestopping systems for expansion joints and through penetrations. When properly installed, these systems effectively contain fire, smoke, toxic fumes, and water within a given area surrounded by firewalls for a two, three, or four hour period, depending on the design specifications.

Surface Preparation

Surfaces must be free of all contamination. Sealant may be applied to damp, porous surfaces. No priming is required.

Application

Refer to Pecora Technical Bulletin #85J and UL Fire Resistance Directory for installation details on fire-rated joint and through penetration systems. For insulating and weatherproofing purposes, fill all window, door, and panel perimeter joints using a resilient backer rod to control sealant depth to 1/2″ (13mm) maximum. For best results, protect sealant from excessive low temperatures and apply above 40°F (4°C). For acoustical purposes, apply continuous beads of sealant to seal perimeters of all sound-rated partitions. Apply sealant in the angles formed by metal components or base-layer panels and abutting surfaces.

Tooling

Tool material flush with surfaces to allow for expected shrinkage and insure
good contact and adhesion to the substrate.

 

Cleaning

Remove excess material with water or a damp cloth before it cures.
Sealant may be painted within 30 minutes after application with a good grade of latex paint.

Precautions

AC-20 FTR 5 gallon is non-flammable, non-toxic, non-irritating and environmentally safe. However, do not take internally.

Maintenance

If the sealant is damaged and the bond is intact, cut out the damaged area and
re-caulk. No primer is required. If the bond has been affected, remove the sealant, clean and prepare the joint in accordance with instructions under “Surface Preparation” and “Application.”

Other Uses

Excellent adhesive, flexibility and durability qualities make AC-20® FTR
ideal for insulating and weatherproofing around windows, doors, panels, siding, duct work, base plates, etc. It is compatible with all common building materials including specialties such as polystyrene, polyurethane, cork, vinyl (not for use on cpvc), foamed and fibrous glass. Used as an acoustical sealant, AC-20 FTR 5 gallon reduces sound transmission in partition systems to maintain specific STC values by sealing spaces around cut-outs and at perimeters of partitions. The sealant cures to a tough rubber to form a long-lasting acoustical seal.
