ABSTRACT:
Hot-tackifying adhesive tape, the adhesive layer of which is an acrylic polymer which is nontacky or poorly tacky at ordinary room temperature, but at any temperature over a wide range of elevated temperatures, it becomes tacky and adheres upon contact to clean substrates without the application of significant pressure. Good bonds are immediately formed at a tackifying temperature without the necessity of crosslinking or other chemical reactions.
