Summary:FIELD: polymers. ^ SUBSTANCE: invention relates to compositions based on polytetrafluoroethylene aqueous dispersions designated for preparing coatings for different aims. The coating composition represents the concentrated polytetrafluoroethylene aqueous suspension comprising the following components, wt.-%: polytetrafluoroethylene, 45-65; fluoroemulsifying agent, 0.1-0.2; nonionogenic surface-active substance Neonol AF 9-n or AFB 9-n, 5-15 (preferably, 8-12) representing a mixture of monoalkylphenol polyethylene glycol esters based on propylene trimers of the formula: R-C6H4O-(CH2CH2O)nH wherein R is alkyl radical isononyl -C9H19 joined to phenol at para-position with respect to hydroxyl group; n is an averaged number of ethylene oxide moles joined to one mole of alkylphenols, 9-12, and water. The composition can comprise additionally ammonium aqueous solution providing pH value 5.0-15.0, glycerol or ethylene glycol in the amount 2-6 wt.-%. The composition is designated for preparing coatings able to endure heating to 370C and for development of different composition materials, among them composition for anti-adhesion and anti-overheating coatings, Invention provides improvement of exploitation and physical-mechanical properties of coating. ^ EFFECT: improved and valuable properties of composition. ^ 4 cl, 3 tbl
