ABSTRACT:
Pressure-sensitive adhesive tape, the adhesive layer of which is a copolymer of alkyl acrylate such as isooctyl acrylate and an acid such as acrylic acid and which differs from the prior art in its high acid content and by including a small amount of lower-alkoxylated amino formaldehyde condensate as a latent crosslinking agent. The adhesive does not become crosslinked until it is heated. After the tape has been applied and heated to crosslink the adhesive, the resultant bonds have outstanding resistance to peel forces combined with surprisingly good resistance to shear forces, especially at elevated temperatures.
