ASTM D4017 Results of Volatile Organic Compound Content (VOC) Testing of Contego (High Solids) Intumescent
Once again Contego (HS) achieves a superior zero VOC rating.
UBC – 26.2 “Test Methods for the Evaluation of Thermal Barriers”
This test is designed to last for 15 minutes with some HUD requirements calling for 20 minutes. The Contego product, applied at a rate of 20 mils (dft) exceeded both requirements and the test terminated shortly thereafter. The specimen was atypically thin (7/16″) and was intentionally split down the middle and gapped 1/8″ to put it at a severe disadvantage.
UBC – 26.3 “Room Fire Test Standard”
After 11 minutes after the start of the test, all indicators – smoke generation, temperature, and threshold heat rise, were all actually declining and continued to decline until the test was terminated.
ASTM D3359 “Standard Methods For Measuring Adhesion by Tape Test”
Using both methods available under ASTM D-3359, adhesion was 100% with 0% paint loss by peeling or removal on a completely nonporous surface.
ASTM E-84.98 (UL-723, ANSI A-2.5, NFPA 255 & UBC 8-1 & 42-1)
“Flame Spread and Smoke Production on OSB”
|Test Name:||ASTM E84-04|
As a control, we applied Contego at a rate of rate of 60 sq. ft./gallon and limited flame spread to 10 and smoke development to 10.
“Flame Spread and Smoke Production on PMDO”
|Test Name:||ASTM E84-04|
We tested Dynea paper fascia overlay on LP’s PMDO Smooth Suffit and limited flame spread to 10 and smoke development to 25 with an application rate of 60 sq. ft./gallon. The paper fascia adds an enormous amount of fuel to the assembly, so the results were particularly outstanding.
UL – 723 (ASTM E-84, ANSI A-2.5, NFPA 255 & UBC 8-1 & 42-1) “Flame Spread and Smoke Production on Douglas Fir” (2 Coats)
This is a standard flame spread and smoke production test. Contego was applied thinner than normally recommended, 2 coats at a spread rate of 145 sq. ft. per gallon, versus our specified 2 coats at 130 sq. ft. per gallon. Regardless, the tests results show an averaged outcome of 0 flame spread and 0 smoke production. Contego gets better flame spread and smoke production results on Douglas Fir plywood than other intumescents get on steel.
NFPA 286 “Standard Methods of Fire Test for Evaluating Contribution of Wall & Ceiling Interior Finish to Room Fire Growth”
Contego passed the 15 minute test well within the limits of thermal performance.
BSS 7239-88 “Test Method for Toxic Gas Generation by Materials On Combustion”
|Location:||Omega Point Laboratories|
We measured toxicity native in the can as well as in a burn condition using a cone colorimeter. The results show that Contego is completely non-toxic. No other product comes close.
