Ure-K Spray Coatings Product Details
Thermal Barrier Testing
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 Corner Test
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.

Enclosed Room Test
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.

Test Results:

  • Flame Spread...........10
  • Fuel Contribution......40
  • Smoke Development...0
