An applicator head for a vacuum coating system includes a manifold shell having opposing shell plates, each including a conduit attachment coupled to a shell aperture. An applicator manifold is affixed to each shell plate. Each applicator manifold includes two coupled manifold plates, with one including a manifold aperture, and each is affixed to the respective shell plate so that each manifold aperture aligns with the respective shell aperture. An applicator channel is formed between the manifold plates of each applicator manifold, and the applicator channel is fluidically coupled to the manifold aperture of each respective applicator manifold. Each applicator channel forms an applicator port at a leading edge of each respective applicator manifold, and each leading edge is configured to be complementary in shape to an edge of a workpiece to be coated. First and second face plates are disposed over the leading edges of the applicator manifolds.

System for applying a coating to a workpiece

Described herein are acoustical panels, comprising: a substrate; a non-woven veil having an airflow resistance of greater than 45 mks rayls, comprising: from about 20 wt. % to about 60 wt. % glass fibers; from about 40 wt. % to about 80 wt. % of a filler; and from about 110 dry g/mto about 135 dry g/mof a coating. Methods of making and using the panels are also described.

Described herein are acoustical panels comprising a substrate and a coated non-woven veil that comprises a coating applied to a non-woven veil, the non-woven veil having an airflow resistance of greater than 45 mks rayls and comprising: from about 20 wt. % to about 60 wt. % fibers; and from about 40 wt. % to about 80 wt. % of a filler; and wherein the coating is present on the non-woven veil in an amount ranging from about 110 dry g/mto about 135 dry g/m. Methods of making and using the panels are also described.

Some embodiments of the present invention provides a method of preparing a thermoformed article composed of polylactic acid that includes the steps of providing a foam sheet comprising polylactic acid having a D-lactic acid stereo-isomer content that is about 3 mole % or less, exposing the sheet to a temperature of at least about 190&#xb0; C., and forming the heated sheet in a mold at a mold temperature that is at least about 50&#xb0; C. and for a length of time to form a thermoformed article having a PLA crystalline content of at least about 10%. Surprisingly, it has been discovered that heat resistant thermoformed articles can be prepared in accordance with embodiments of the invention wherein the time required for forming the foam sheet into a molded article is less than about 10 seconds.
