A roofing shingle includes a buttlap portion with a butt edge and a headlap portion with a head edge. The roofing shingle includes a coated mat which is a roofing mat coated with an organic-based coating material. The roofing shingle also includes a water impermeable sheet adjacent to the coated mat. In one embodiment, the headlap portion of the coated mat is mostly replaced by the sheet. In another embodiment, the roofing shingle has a limited width. In a further embodiment, the roofing shingle is reduced in weight compared to a conventional shingle.

Roofing shingle including sheet as headlap

The subject invention relates to a foundry binder system which cures in the presence of a volatile amine curing catalyst comprising (a) an epoxy resin, (b) an acrylated organic polyisocyanate, (c) a reactive unsaturated acrylic monomer, acrylic polymer, or mixtures thereof, and (d) an oxidizing agent comprising a hydroperoxide. The foundry binders are used for making foundry mixes. The foundry mixes are used to make foundry shapes which are used to make metal castings.

Foundry binder of epoxy resin, acrylated polyisocyanate and acrylic

The subject invention relates to a foundry binder system that cures in the presence of a volatile amine curing catalyst. The binder system comprises (a) a compound containing at least two active methylene hydrogen atoms, (b) an organic polyisocyanate (c) a reactive unsaturated acrylic monomer and/or polymer, (d) an oxidizing agent, and preferably (e) an epoxy component. The foundry binders are used for making foundry mixes. The foundry mixes are used to make foundry shapes that are used to make metal castings.
