Abstract: The present invention provides an adhesive composition which is a primerless urethane-based adhesive and has high adhesive force with respect to a polyolefin-based resin. An adhesive composition according to the present invention is a two-liquid type urethane-based adhesive composition comprising: a main agent which comprises (A) a urethane prepolymer having an isocyanate group at the end thereof, (B) a polyfunctional isocyanate compound having an alkoxysilyl group which can be obtained through a reaction of a silane compound having at least two alkoxysilyl groups in one molecule and a polyisocyanate having an isocyanate group at the end thereof and (C1) a first curing catalyst; and a curing agent which comprises (D) a hydrophobic polyol and (C2) a second curing catalyst.

Abstract: A method of processing starch grain material for use in a fermenting process subsequently thereto is disclosed. Prior to subjecting the material to the fermenting step, the material is subjected to a microwave irradiating step and this microwave irradiating step is effected on the starch grain material which is in a dry condition storable at a room temperature with simultaneous application of hot air current thereto. A method of manufacturing a fermented product using the material processed by the method above is also disclosed.
