ABSTRACT:
In manufacturing industrial products such as automobiles, it is known to adhere rigid solid objects such as emblems, the manufacturer's name, body trim, and so forth to the automobile body by means of a relatively thick sheet of resilient foamed plastic such as polyurethane, for example, 30 one thousands of an inch (30 mils) in thickness, coated on each face with a pressure sensitive adhesive. This provides a cushioning effect to take care of the wide variations in the uniformity of the emblems and further provides a cushion so that when the emblem is struck a blow it does not pop off as would be the case with a thin adhesive layer absent the foam layer.
The present invention, by providing a permanently pressure sensitive adhesive composition as a thick, backing-free sheet with the resilience of a soft rubber and certain critical characteristics as to the physical nature of the adhesive, makes it possible to completely eliminate the foam sheet and yet have a thick cushioning material which will permanently adhere the rigid body to the automobile or other surface. Specifically, the adhesive when cured retains its pressure sensitive characteristics, has the resiliency of a soft rubber, a thickness of 8 mils, and certain other critical physical characteristics relating to tensile strength, glass transition temperature, and elongation.
