The present invention relates to an improved formaldehyde-free coated fibrous substrate. The coating includes a crosslinked binder system which forms three dimensional networks when heat cured. After the coating is applied to the back of fibrous substrate and cured, the coating is capable of hygroscopic expansion which imparts excellent anti-sag properties. The coating is compatible with other coating systems with neutral or mild alkaline pH. The improvement being the binding system is neutralized with a volatile base so that it evaporates quickly so as not to hinder the cross-linking reaction.

A laminated surface covering including a facing material made of vinyl and a backing material comprising a rubber component. The rubber component comprising at least a matrix of bonded rubber granules. A bonding material disposed between the facing material and the backing material. The facing material configured to melt at a temperature between 165° F. and 248° F. infiltrating the backing material thereby essentially encasing the rubber granules of the matrix and providing fire retardation and smoke suppression qualities.

Fiber-reinforced coated mats and fiber-reinforced coated mat-faced panels are provided herein, along with methods for making the same. Fiber-reinforced coated mats include a mat with a fiber-reinforced coating on one surface. Fiber-reinforced coated mat-faced panels include a fiber-coated mat and a panel material in contact with a surface of the mat opposite the fiber-reinforced coating. Methods include applying a fiber-reinforced coating to a surface of a mat to form a coated mat and drying the coated mat to cure the fiber-reinforced coating. Some methods also include combining the mat with a panel material to form a mat-faced panel.

Non-conductive films for constructing lighter than air balloons are provided. A non-conductive film may include multiple layers of gas barrier polymers. An outer surface printable layer and an interior heat or ultrasonically sealable layer may also be included. Each gas barrier film may include multiple (e.g., from 3 to approximately 75) barrier layers. A gas barrier core has a nano-layer structure. A gas barrier core may also include a biodegradable film or a bio-based film. A non-conductive film may include a metal layer for enhancing gas barrier properties. The metal layer may be discontinuous. The metal layer may be conductive and coated with an insulating top coat.

A laminate includes the following substantially coextensive layers in the following order:

(a) a non-sealable, self-supporting, thermoformable copolyester film layer having a first surface and a second surface, the second surface constituting an outermost, exposed surface of the laminate;

(b) a laminating adhesive layer on the first surface of the thermoformable copolyester film layer; and

(c) a self-supporting, thermoformable structural film layer having a first surface and a second surface, the first surface contacting the laminating adhesive layer.
