The present invention provides a barrier film laminate including a first barrier film that includes a first substrate layer and a first barrier layer formed on the first substrate layer, a second barrier film that includes a second substrate layer and a second barrier layer formed on the substrate layer, and an adhesive layer. In the barrier film laminate, the first barrier film is bonded with the second barrier film so that the first barrier layer faces the second barrier layer with the adhesive layer interposed therebetween. In one embodiment of the barrier film laminate, the adhesive layer is formed of an adhesive containing an epoxy resin, a curing agent having an amino group, and either a silane coupling agent having an epoxy group or a silane coupling agent having an amino group and two hydrolyzable functional groups.

Composite gypsum panels and methods of making thereof are provided. The composite gypsum panels can include one or more gypsum panel substrates having one or more urethane layers applied thereto. The urethane layers can be or can include foamed urethane layers, provided for structural integrity while being lighter than conventional gypsum panels having the same overall thickness. The panel can have a dense coating layer, a foamed coating layer, or both a dense coating layer and a foamed coating layer. The dense coating layers and foamed coating layers can each offer certain advantages over conventional gypsum panels. Additionally, in various aspects, the composite panel includes a water-resistant barrier and increased nail and screw retention.

Provided is a method of manufacturing a liquid crystal panel employing a photocurable adhesive composition which causes no damage to adherends during bonding and which, when used in bonding rugged adherends, can bond the adherends without forming a gap therebetween. The photocurable adhesive composition of the inventive method comprises (A) 100 parts by mass of a urethane (meth)acrylate oligomer having a weight-average molecular weight of 20,000 to 100,000, (B) 5 parts to 70 parts by mass of a phenoxy resin, and (C) 0.1 parts to 10 parts by mass of a photopolymerization initiator. The uncured composition has a loss tangent (loss modulus/storage modulus) of less than 1 at 25° C. and the temperature at which the loss tangent of the uncured composition reaches 1 or more is 80° C. or less.

There is provide a curable composition comprising a) one or more reactive components that cure upon exposure to suitable conditions, and b) a sulfur impregnated particulate solid which acts as a release agent for sulfur during the cure process; and c) optionally a solvent.

A composition comprising: a one part adhesive composition comprising a) one or more isocyanate components; b) one or more catalysts for the reaction of isocyanate groups with active hydrogen containing groups; c) one or more fillers which do not enhance the formation of voids during curing; d) one or more fillers having basic character; and a cure accelerator comprising: e) one or more liquid carriers; f) water; and g) one or more paste forming agents. The one part adhesive composition may be used alone where ambient temperature and humidities afford reasonably rapid cure rates. The cure accelerator may be used when temperatures and/or humidities are sufficiently low such that the cure rate of the adhesive alone is not acceptable for a particular use.

Techniques and mechanisms for generating a laminate structure. In an embodiment, a layer of adhesive material is disposed on a surface of a glass plate or other constituent layer for a laminate. Prior to an application of another constituent layer, the adhesive layer is selectively cured to form in the adhesive layer at least a first portion which adjoins a second portion of the layer of adhesive material. In some embodiments, a level of cure of the first portion is greater than a level of cure of the second portion.
