A membrane composite comprising a membrane panel having opposed first and second planar surfaces and a fabric backing secured to a first planar surface through a UV-cured adhesive disposed on said planar surface of said membrane.

Fabric-backed roofing membrane composite

A roof assembly comprising: a roof deck; a thermoplastic membrane covering the deck; and a fabric having disposed thereon expandable graphite.

Fire-resistant roof system and membrane composite

A method of reroofing, the method comprising of applying to an existing roof surface a membrane composite including a pre-applied adhesive layer by mating the adhesive layer to the existing membrane.

Method of reroofing

A composite comprising (i) a pressure-sensitive adhesive component including first and second planar surfaces; (ii) a fire-resistant fabric adhered to the first planar surface; and (iii) a cap layer disposed on said fire-resistant fabric opposite said asphaltic component.

Flame-resistant composites for roofing underlayment

A method for preparing a roofing membrane in the form of a roll, comprising the steps of: providing a polymeric membrane; providing a fabric having a coating disposed thereon; attaching the polymeric membrane to the fabric to form a composite; and rolling the composite. Wherein the coating includes expandable graphite dispersed within a binder.

Coated fabrics including expandable graphite

A roof system comprising a roof substrate, a first membrane including first and second opposed planar surfaces, and a second membrane including opposed first and second planar surfaces, where said second membrane is adhered to said roof substrate through an adhesive disposed on said roof-substrate contacting portion of the first membrane, and where said second membrane is adhered to said first membrane through said adhesive disposed on a lap portion of said second membrane.

Fully-adhered roof system adhered and seamed with a common adhesive

A multi-layered membrane comprising a first thermoplastic layer and a second thermoplastic layer, where the second layer includes expandable graphite.

Thermoplastic membranes containing expandable graphite

An apparatus and related methods for constructing articles with cured pressure-sensitive adhesives comprising (i) a coater that applies a curable adhesive to a membrane; (ii) a cross-linking apparatus adapted to receive said membrane with said curable adhesive, said cross-linking apparatus comprising a light source positioned a first predetermined height above an aperture plate having an aperture therethrough, wherein said aperture plate is positioned a second predetermined height, said first predetermined height and said second predetermined height selected to define an exposure area of light emitted from said light source on to said curable adhesive to form a composite product; and (iii) a roll adapted to receive said composite product, said roll adapted to control a speed at which said membrane with said curable adhesive is exposed to light from said light source.

Process for preparing construction articles with cured pressure-sensitive adhesives

A method is provided for forming an adhered membrane roof system that meets Factory Mutual (FM) 4470/4474 standards for wind uplift. The method comprises applying a bond adhesive to a substrate on a roof to form an adhesive layer and applying a membrane directly to the adhesive layer. The bond adhesive includes a moisture-curable polymer.

Bonding adhesive and adhered roofing systems prepared using the same

A multi-layered membrane comprising a first thermoplastic first layer and a second thermoplastic layer, where the second layer includes expandable graphite.

A roofing membrane comprising at least one layer of a cured rubber and expandable graphite dispersed within the cured rubber.
