Method of preparation and application of polyurethane adhesive

A method for preparing and applying a polyurethane adhesive, the method comprising:

• mixing an isocyanate and an amine curing agent of a polyurethane compound;
• pouring the polyurethane compound onto a first non-stick film positioned on a planar mold;
• placing a second non-stick film on an upper surface of the polyurethane compound;
• applying a pressure to the first non-stick film and/or the second non-stick film to give the polyurethane compound a thickness of approximately 0.005 inches;
• allowing the polyurethane compound to solidify at room temperature for a first period of time to form a polyurethane adhesive;
• cutting the polyurethane adhesive and the two non-stick films according to a size of the mating surfaces of the two objects to be joined together;
• placing the cut polyurethane adhesive in contact with one of the mating surfaces and hold the other mating surface in contact with the polyurethane adhesive;
• and
• heating the cut polyurethane adhesive to a curing temperature.

A method for preparing and applying a polyurethane adhesive, the method comprising:

• mixing a part A component and a part B component of a polyurethane compound;
• pouring the polyurethane compound onto a non-stick surface of a planar mold;
• allowing the polyurethane compound to solidify for a first period of time to form a polyurethane adhesive;
• feeding the polyurethane adhesive through a pair of pinch rollers to form a polyurethane adhesive sheet having a specified thickness;
• cutting the polyurethane adhesive sheet according to a size of the mating surfaces of the two objects to be joined together;
• placing the cut polyurethane adhesive sheet in contact with one of the mating surfaces and hold the other mating surface in contact with the polyurethane adhesive sheet;
• and
• heating the cut polyurethane adhesive sheet.
