1. Product Description
3MTMFire Barrier Moldable Putty+ consists of a
synthetic elastomer designed for use as a one part,
intumescent fire resistive putty used to restore the
integrity of fire rated building construction. Up to a four
hour fire rating is achieved when tested in accordance
with the time/temperature curves and water hose
stream tests of UL 1479 and ASTM E 814.This is
achieved by the unique intumescent (expanding when
heated) and high strength insulating char-forming
properties of this material. 3M Moldable Putty+ Stix is
approximately 1.4 inches (35,6 mm) in diameter by 11
inches (279 mm) in length. Moldable Putty+ Pads are
4 x 8 x 1/8 inches (102 mm x 203 mm x 3,2 mm), 7 x
7 x 1/8 inches (178 mm x 178 mm x 3,2 mm), and 9.5
x 9.5 x 1/8 inches (241,3 mm x 241,3 mm x
3,2 mm), and Moldable Putty+ Cable Wrap is 2 x 8 x
1/8 inches (51 mm x 203 mm x 3.2 mm) approximate
dimensions.
Features
•
Tested to UL 910 flammability test
•
Halogen-free formula: Free from corrosive gases
during a fire, making it safe for building occupants
and sensitive electrical equipment.
•
Minimal odor.
•
Long shelf-life: Stix and pad packages can be
sealed for reuse.Putty will not dry out or crumble.
•
Easily re-enterable.
•
Provides a draft and cold smoke seal in the
installed condition, even before any temperature
rise occurs, resultant from a fire.
•
Adheres to all common building surfaces (Cement,
gypsum, wood and plastic), including metal and
plastic electrical boxes.
•
One part, solventless pads or stix are easily hand
molded, with no damming required (this applies to
non-insulated metal pipe/conduit), allowing for easy
application.
•
Intumescent: expands when heated, forming a hard
char, preventing the transmission of hot gases and
fire.
•
Designed to meet the intent of NEC 300-21 (NFPA
70). ICBO, SBCCI and BOCA Building Codes.
•
No special tools required.
•
Contains no asbestos, non-toxic.
2. Applications
Used to seal cable (including fiber optic inner duct
and cable), insulated pipe, electrical conduit, and
metal pipe, penetrations against air draft, smoke,
noxious gas and flame propagation.

6. Installation Techniques
The drawings on the next page show an example of
one of the UL classified firestop systems using 3M
Fire Barrier Moldable Putty+. Drawings for other
tested firestop systems are available.
All surfaces shall be clean and free of dust, grease,
oil, loose materials, rust or other substances to
ensure adequate adhesion. Remove desired amount
of 3M Fire Barrier Putty+ from stix or pads and install
putty into the appropriate 3M firestop system. Note:
Make sure the 3M Fire Barrier Putty+ is in complete
contact with the inside surface of the opening and
also the surface of the penetrating item.
