Abstract
Abstract A fire retardant antistatic coating and coated substrate. The coating includes a mixture of a radiation curable halogenated prepolymer, an effective amount of a quarternary ammonium compound antistatic agent and an effective amount of an antimony pentoxide flame retardant agent. A coated substrate having a substrate film material coated with the above coating is included. A method for making a fire resistant and antistatic film which includes the steps of: (a) providing a substrate film; (b) preparing the coating by mixing a radiation curable prepolymer with an effective amount of a quarternary ammonium antistatic compound and an effective amount of an antimony pentoxide fire retardant compound; (c) the coating is then applied to the film material; and (d) the coating is contacted with electron radiation in an amount sufficient to cure the coating.
