Abstract: A system for applying an adhesive includes an air flow path for conveying compressed air and an adhesive flow path for conveying liquid adhesive. The system includes an air heater coupled to the air flow path and configured to heat the compressed air and a liquid adhesive heater coupled to the adhesive flow path and configured to heat the liquid adhesive. The system also includes an applicator positioned downstream from the air and liquid adhesive heaters. The applicator is configured to receive the liquid adhesive from the adhesive flow path and the compressed air from the air flow path. The applicator is further configured to spray the liquid adhesive from the applicator using the compressed air.

Abstract: A polyamide that includes the reaction product of dimer acid (e.g. a dimer acid including at least 98% by weight dimer), caprolactam, hexamethylene diamine, sebacic acid, and optionally, chain terminating agent.

Abstract: The present invention is a hot melt adhesive composition comprising at least one ingredient present in an encapsulated form. The encapsulated ingredient may be any known hot melt adhesive formulation ingredient as well as any hot melt adhesive additive such as antioxidants and fragrances for which there is a desirable change in adhesive properties by isolating such ingredient for a duration of time. The encapsulated ingredient is released from the shell by means of pressure, temperature, diffusion, pH, light, radiation, ultrasound, and combinations thereof. Hot melt adhesive compositions comprising at least one encapsulated ingredient are useful for a variety of novel products including self-supported friction glue sticks, non-tacky pelletized pressure sensitive adhesives, cohesive adhesive systems, hot melt adhesive compositions exhibiting improved thermal stability and odor, as well as for a variety of other adhesive applications.

Abstract: Polysulfide corrosion inhibiting compositions used as adhesives and sealants for aircraft and military shelter industries are described as two-part compositions including a curing agent in the second part and a particular corrosion-inhibiting composition milled into the polysulfide in the first part where the corrosion inhibitors include a combination of a phosphosihicate with a mixture of alkali metal molybdate, ammonium benzoate, alkali metal nitrite, and benzotriazole.

Abstract: An adhesion promoter composition and method for enhancing adhesion between a polysulfide polymer and a thermoplastic substrate is provided having a solid resole phenolic resin and a compatible organic solvent, optionally containing a chlorinated polyolefin.

Abstract: Normally water insoluble hot melt adhesive compositions containing structural polymers such as A-B-A block copolymers, butyl rubbers, polyesters, ethylene vinyl acetates, ethylene acrylic acid polymers can be made sensitive to the action of water using an effective water sensitizing amount of a polyalkyloxazoline polymer in the hot melt adhesive. The polyalkyloxazoline polymer can be incorporated into a single phase adhesive composition with the structural polymer using an effective amount of a hydroxyl or carboxylic acid compound.

Abstract: A water soluble dermal treatment film for dressing burns, surface wounds, cuts, scrapes, rashes or other dermal wound or lesion comprises a flexible sheet-like dressing made of polyalkyloxazoline. The dressing can have a structural layer and a pressure sensitive adhesive layer. The structural layer can be made of a polyalkyloxazoline composition formulated to obtain a flexible structural sheet. The pressure sensitive adhesive layer can be formulated to obtain pressure sensitive properties, maintaining the treatment film in position during its use. At such time the treatment film is to be removed, it can be removed without harsh scrubbing methods with a warm aqueous spray or soak. The sheet-like treatment means can be reinforced or impregnated with medicinal compositions to induce healing, reduce infection or stabilize the skin surface.
