A method of manufacture of a composite material comprising the steps of providing a mixture of polyvinyl alcohol and a fibrous or non-fibrous cellulosic material; heating the mixture to a temperature of 190 C. or greater; allowing the mixture to react to form a composite mixture; and allowing the mixture to cool to form an isotropic solid composite material.

The present invention relates to a sizing composition for mineral fibers, especially glass fibers or rock fibers, containing a liquid phenolic resin having a free formaldehyde content, expressed with respect to the total weight of liquid, of 0.1% or less and an extender. Preferably, the liquid phenolic resin is mainly composed of phenol-formaldehyde and phenol-formaldehyde-amine condensates and has a water dilutability, at 20 C., at least equal to 1000%. Another subject of the present invention is the insulating products based on mineral fibers treated by said sizing composition.

An adhesive formulation is provided that is a waterborne bonding adhesive for adhering sheet membranes that may incorporate a solid plasticizer. The formulation is fast-curing and develops bond strength rapidly after application to a substrate as the adhesive dries, when the sheet membrane is mated to the substrate. The fast-curing characteristic is important to ensure the membrane is not displaced from the surface in windy exterior applications. The adhesive is formulated to form the bond between sheet membranes to substrates that illustratively include, steel, wood, concrete, roof boards, insulation, and fiberglass mat roof boards.

Disclosed is related to an adhesive composition for encapsulating an organic electronic element and an organic electronic device comprising the same. The adhesive composition includes a curable compound having no carbon-carbon unsaturated group, a thermal initiator, and a photo-initiator. The adhesive composition can form a structure capable of effectively blocking moisture or oxygen introduced from the outside into the organic electronic device, thereby securing the lifetime of the organic electronic device, can realize a top emitting organic electronic device, and can prevent defects such as dark spots which may occur in the organic electronic device.
