A vapor barrier coating solution for polymeric articles is provided which contains a selected layered silicate dispersed in a cationic aqueous metal polysilicate, wherein the weight fraction layered silicate of total inorganic solids in the dry coating ranges from above 0 to about 99 percent. Preferably the layered silicate is vermiculite and the polysilicate is lithium polysilicate. Methods for producing and using this coating solution are also included. |
