Low Smoke density and toxicity properties of
Colorado Eco Coatings Polymer Coatings in the event of fire
Colorado Eco Coatings Polymer Coatings are composed almost
entirely on compounds of carbon,
hydrogen and oxygen. Unlike many paints, it contains:
no reactive ingredients
no phthalates
no halogens
no isocyanates
no heavy metals
On burning, therefore, the fumes are principally made up of
carbon dioxide and water. As a result the toxicity of the fumes in a
fire situation is extremely low. For instance:
The index of toxicity of the smoke generated is 1.78 according
to test method NES 713. This is well below the Royal (British) Navy
requirements of 5.
The index of toxicity of the smoke according to the test
method BS 6853:1999 used for projects in the London Underground is
0.21. This is well below even the most stringent requirement of an
index of 1.
Furthermore, the rate of generation of smoke and the density
of the smoke are relatively low:
The US Railroad requires that the smoke generated should be
less than an index of 100 at 1.5 minutes, 200 at 4 minutes etc. The
smoke index generated from PPA 571 when burning is only 110 after 20
minutes.
The smoke density index according to the test method BS
6853:1999 used for projects in the London Underground is 1.13 (A0 (ON))
compared to a requirement of 2.6.
Under BS 476, Colorado Eco Coatings Polymer Coatings can be
considered to be Class 0 and, though not specifically flame retardant,
more than meets the requirements for coatings in tunnels, enclosed
buildings and on passenger trains.
