Abstract: One aspect of the present invention is an adhesive composition formed from two packs. One pack includes an isocyanate-functional prepolymer formed by reacting a polyisocyanate with an alcohol (e.g., polyol). The isocyanate equivalents from the polyisocyanate exceed the hydroxyl equivalents from the alcohol. The second pack is an aqueous polymer emulsion. These two packs are combined to form the novel adhesive composition. Another aspect of the invention is a method for joining together two surfaces of wood products by application of an adhesive thereto. The first step in this method is to mist with water the wood product surfaces to be joined. An adhesive composition then is applied to the misted wood product surfaces. Alternatively, the water misting can be replaced with an aqueous emulsion being part of the adhesive composition. Finally, the adhesive composition is cured.

Abstract: Disclosed are a method of manufacturing a magnetic head slider and a method of fixing row bars, which realize improved fabrication accuracy without increasing manufacturing costs and can prevent adhesion of a foreign matter to a magnetic head slider. After forming a number of thin film magnetic head devices on a wafer by thin film process, the wafer is cut into a plurality of row bars. Before a rail is formed in a predetermined surface of each of the row bars by photolithography, a surface opposite to the surface to be processed of the row bar is bonded and fixed to a support substrate of a wafer shape. A protective film obtained by conducting a heat treatment on a polyimide precursor at temperature lower than temperature at which the polyimide precursor becomes polyimide is formed on the surface of the support substrate. A curing agent film containing a curing agent which promotes setting of the adhesive for bonding the row bars is formed on the surface of the protective film.

In addition, they avoid spontaneous, merely superficial hardening.
