Abstract
Abstract A fire retardant coating composition useful as a paint or as a mastic is composed of ultrafine pulverized fly ash, a low viscosity vinyl acrylic type emulsion polymer as a binder and water. The composition also preferably contains one or more of a dispersant, a defoamer, a plasticizer, a thickener, a drying agent, preservative, a fungicide and an ingredient to control the pH of the composition and thereby inhibit corrosion of any metal surface to which the composition is applied.

Claim 1
Independent Claim
173 words
A fire retardant coating composition consisting essentially of: ______________________________________
finely pulverized fly ash
24%-50%
a binder consisting essentially
of low viscosity vinyl acrylic
type emulsion polymer having the
properties of being stable and
compatible with fire retardant
ingredients and of forming a film
which is tough, flexible and
resistant to cracking, has out-
standing permanence, durability
and binding capacity and is flame
resistant, smokeless and free
of emission of toxic vapors when
heated, said binder being selected
from the group consisting of
UCAR Latex 5000 and RHOPLEX
AC-234 7%-31%
Water 8%-48%
Fine Fibreglass Flakes
of Fibre 0%-10%
Inorganic Pigment 0%-10%
Low Foaming Dispersing Agent
0%-5%
Water Capatible Defoamer
0%-10%
Plasticizer selected from the
group consisting of 2,2,4-trimethyl
1,3 pentanediol monoisobutyrate
and tricresyl phosphate 0%-1%
Thickner consisting essentially
of hydroxyethyl cellulose
0%-1%
Drying Agent 0%-6%
Water Soluble Preservative
0%-1%
Compatible Fungicide 0%-1%
2-amino-2-methyl-1-propanol
to control the pH of the
composition and inhibit corrosion
of metal surfaces to which the
composition is applied 0%-1%
Amorphous Silica 0%-32%
Surfactant consisting essentially
of nonylphenoexy-poly(ethyleneoxy
ethanol 0%-1%
