| Ure-K Spray Coatings
Ure-K was tested and has been accepted by National Code Bodies
and Fire Insurance Companies as a thermal barrier coating over polyurethane
foam, used as an interior insulating product. The following
tests satisfied these requirements:
| Full Scale
Test Method: A full scale corner test was conducted
in accordance with Factory Mutual Building Corner Fire Test Procedure
with the test surface applied to the interior of the simulated building
structure. The structure was 25 feet high consisting of
a corner wall configuration and a roof or ceiling membrane. One
wall was 50 feet and the other 38 feet long. The test surface
was applied to both the walls and ceiling. Ure-K
was applied 3/4" thick over 1-1/2" polyurethane with a flame spread
rating of over 200 in the ASTM-E-84 Tunnel Test procedure. No
sprinklers were used in this test.
Test Conclusions: Ure-K Spray Coating,
applied 3/4" thick is approved for building interior use as a protective
coating to delay the ignition and reduce the surface burning rate
of low melting, combustible rigid spray-on polyurethane and protect
its dimensional stability for a period of 15 minutes in a non-combustible
occupancy for unsprinklered wall and ceiling configuration.  Factory
Mutual Research Corporation.
Test Method: The test panel consisted of a urethane
foam over which Ure-K was applied. The urethane
foam had a flame spread rating of less than 75, per the manufacturer,
and was applied to a 1/2" sheetrock to a thickness of approximately
3". Ure-K was spray applied over the foam to a nominal
thickness of 1 inch.
Test Conclusion: The finished rating is the shorter
time span for a 250°F average of the five thermocouples, or
a 375°F maximum temperature rise of one thermocouple above
ambient on the unexposed face of the thermal barrier. Based
upon the above criteria, Ure-K as tested had a finished rating
of 25 minutes and 1 second.
Test Method: The test facility consisted of a fully
enclosed 8 x 12 x 8 foot room. The urethane foam, with
a flame spread rating of less than 75, was spray applied to the interior
of the room. A 1" application of Ure-K covered the
urethane. The wood crib fuel source was consturcted of
1.5" x 1.5" sticks of Douglas Fir wood in 15" lengths. The
crib had a weight of 30 lbs. Temperatures in the room reached
a high of 2,013°F. The length of the test was 30 minutes.
Test Results: Under these specified test conditions,
the Ure-K material did substantially remain in place. The
Ure-K did crack open and recede due to charring in several
areas, most notably in the crib corner area.
Test Method: To evaluate performance of the Ure-K
in relation to that of asbestos cement board and red oak flooring
under similar fire exposure. The results are expressed
in terms of flame spread, fuel contribution and smoke development
during a 10 minute exposure and are recorded as a ratio with asbestos
cement board - 0 and red oak flooring - 100.

Heat Loss Characteristics
Ure-K has a K-factor of .28 BTU/hour/square foot/1 inch.
| Physical Characteristics
Density: Applied 4.0 - 4.5 lbs per cubic foot
Noise Reduction Coefficient: .75 NRC when sprayed 1" on solid
Scope: The contractor shall furnish all labor, materials and
equipment required for the installation of Ure-K Spray Coating as
manufactured by International Cellulose Corporation, Houston, TX.
Condition of the Surface: Surface to be sprayed shall be
cleaned of all loose dirt, paint, grease, oil or any materials which would
prevent a good adhesion of the Ure-K Spray Coating to the urethane.
Materials: The Ure-K Spray Coating fiber is a cellulosic
insulation material. This fiber, with its special built-in
binder, shall be the only fiber used. The liquid adhesive shall
be UK-100 emulsion. This adhesive bond, after setting up, is
resistant to water, freezing.
Application: All Ure-K Spray Coating installed shall
conform to the applicable requirements of national and local building
codes and all other authorities having jurisdiction.  The application
of Ure-K Spray Coating shall be in strict accordance with the directions
and specifications of the manufacturer or contractor approved by the manufacturer.
