An aerosol coating composition contains at least one film-forming resin, trans-1-chloro-3,3,3-trifluoropropene and at least one propellant such as CO.sub.2. The aerosol coating composition is non-flammable and compatible with polyethylene terephthalate. The film-forming resin may be acrylic resins, alkyd resins or mixtures thereof. A glycol ether solvent may be present. The coating composition may have low toxicity, be non-ozone depleting, have low or no VOC, be low in maximum incremental reactivity and/or be low in global warming potential. A method of coating a substrate with the aerosol coating composition comprises providing at least one film-forming resin selected from the group consisting of acrylic resins, alkyd resins, and mixtures thereof and trans-1-chloro-trifluoropropene in a container comprising polyethylene terephthalate, which is charged with a propellant comprising carbon dioxide. The aerosol coating composition is non-flammable. The composition is applied to a substrate and allowed to dry.

A pressurised dispensing container (10) comprising a container (11) for product to be dispensed, and a valve fixed to the container, wherein the container contains a propellant comprising 1,1-difluoroethane or a derivative thereof and optionally ethanol. The valve comprises a valve stem (15), a valve body (16, 18) and one or more seals (20, 21), the valve stem being slidable within the valve body, the one or more seals co-operating with the valve stem for regulating discharge of a fluid. The valve further comprises a sealing gasket (14) for sealing the valve to the dispensing container. The one or more seals (20, 21) is/are formed from (i) an elastomeric composition, preferably an elastomeric composition comprising an ethylene-propylene-diene terpolymer. The sealing gasket (14) is formed from (ii) an elastomeric composition comprising an isobutylene polymer or co-polymer thereof.
