Contego IFRM coatings continue to lead the Intumescent Fireproofing Industry, pushing the standards higher with each test result. Contego HS RFB Intumescent coating was tested April of 2024 at Intertek Laboratories in Elmendorf, TX achieving a new CII/IF 120-02 listed design.
Contego High Solids RFB is one of two water-based IFRM Manufacturers that can provide 2-hour fire resistance ratings on a W8X10 column with a listed design.
Design No. CII/IF 120-02 encompasses the following structural steel:
SOLID STRUCTURAL STEEL COLUMN: Use solid steel sections, I-shape or W-shape, having nominal Hp/A or W/D section factors based on four-sided exposure. Refer to Table CII/IF 120-02 for specific Hp/A or W/D section factors.
Save Time and Project Cost!
With 85 Hp/A listed data points, Contego’s design will cover your structural steel Wide Flange Column needs with 30-40% less product and labor requirements depending on column size and manufacture used. The chart below compares DFT (dry film thickness) coating requirements for a 1-hour and 2-hour fire resistance rating on wide flange columns with the leading intumescent manufactures listed designs in the USA currently.

Contego IFRM coatings continue to lead the intumescent fireproofing industry, pushing the standards higher with each test result. Contego HS RFB intumescent coating was tested December of 2023 at Intertek Laboratories in Elmendorf, TX achieving a new CII/IF 120-01 listed design.
Design No. CII/IF 120-01 encompasses the following structural steel:
Hollow Rectangular or Circular Structural Steel Columns: Use hollow steel sections, rectangular or circular shape, having nominal Hp/A or W/D section factors based on four-sided exposure to meet 1, 1 1-2, 2 HR Fire Resistance tested to ASTM E119, UL-263, CAN/ULC-S101 assembly ratings.

Contego is pioneering the (IFRM) intumescent fireproofing industry, pushing the standards higher with each test result. Testing the 1st 2HR UL D603 Composite Steel Deck Floor/Ceiling Design back in 2018, now testing the 1st Full Scale Dimensional Lumber Floor/Ceiling (13ft x 19ft OSB, I-Joist Assembly)
Location: Intertek Laboratories Test Date: 8.30.2022
The test specimen was tested load bearing with a 40 lb/ft2 superimposed load applied in four increments of 25% before the fire exposure, allowing for stabilization of deflection after each increment.
Contego HS Intumescent applied at a 40 Mil DFT on the Full Scale Dimensional Lumber Floor/Ceiling (13ft x 19ft OSB, I-Joist Assembly) 2×12 wood joists spaced 16-in. oc 23/32 Category OSB tongue and groove OSB subfloor with 7/8-in. Red Oak flooring planks, tongue and groove installed as finish flooring met a fire endurance period of 50 minutes before flaming was seen through the top of the sample.
When applying a finish coat to this assembly you will achieve an additional 16 minutes to total a 1:06 hour/minute fire resistance as per our ASTM E119/UL263 “The Effect of Top Coat on Contego HS Intumescent RFB” test results.
The specimen was evaluated in accordance with the following:
ASTM E119-20, Standard Fire Test Method for Fire Tests of Building Construction
CAN/ULC S101, Standard Methods of Fire Endurance Tests of Building Construction
UL 263, Standard for Safety for Fire Tests of Building Construction and Materials
The floor assembly consisted of the following:
13ft x 19ft overall area
2×12 wood joists spaced 16-in. oc spanning the 13-ft width. Center joist was a double 2×12. Fourth joist from the center in either direction was also a double 2×12 joist.
23/32 Category OSB tongue and groove OSB subfloor attached to wood framing with #9 deck screws spaced 12 in. oc.
7/8-in. Red Oak flooring planks, tongue and groove installed as finish flooring, fastened with 2-in. long brad nails. Three brad nails evenly spaced along width of each board at each joist location.
Underside of the floor assembly was primed with a water base interior and exterior primer.
Contego Passive Fire Barrier HS, Lot No. HS-1053, was sampled by Intertek’s Frances Martinez on June 28, 2022. This coating was first applied by brush along the wood seams. Then it was spray-applied in three coats. The coating was applied to the overall fire side of the sample with an overall average of 55.3 wet mils (39.8 dry mils).
100% silicone was used as filler between double joists. The silicone sealant was then coated with the Contego Passive Fire Barrier HS with brush application.
The assembly was then allowed to cure for 32 days before fire testing
The Contego International floor/ceiling assembly described within this test report met a fire endurance period of 50 minutes, as per the specified performance requirements of ASTM E119, Standard Fire Test Method for Fire Tests of Building Construction and Materials.
The test specimen was tested load bearing with a 40 lb/ft2 superimposed load applied in four increments of 25% before the fire exposure, allowing for stabilization of deflection after each increment. The full superimposed load was applied for 30 minutes before the start of the fire test.
