Abstract:
A dispensing unit, which utilizes a chemical reaction or phase transition to soften a material into a flowable state, is described. The material comprises an adhesive, sealant or caulk.
Abstract:
A two-part, solvent-free laminating adhesive including a Part A that is a liquid mixture of a first polyol and a hydroxyl functional acrylic polymer having a molecular weight of no greater than 15,000g/mole, and a Part B that is an isocyanate-terminated polyurethane prepolymer. The adhesive is especially suited for making flexible laminates for use in food packaging. When adhered two polymeric film materials and in cured form, the adhesive provides substantially no contribution to the oxygen barrier properties of the laminate.
Abstract:
A polyurethane adhesive composition that includes a polyurethane prepolymer that includes the reaction product of a first polyol component that includes glycerol monoester and a polyisocyanate, and a second polyol. A polyurethane prepolymer that includes the reaction product of glycerol monoester, a hydroxy functional triglyceride, and a polyisocyanate.
