Pressure-Sensitive Adhesives

Published in Gerald L. Schneberger, Adhesives in Manufacturing, 2018

A pressure-sensitive tape consists of backing material to which a PSA has been applied on one side. A thin primer is sometimes required in order to anchor the adhesive to the backing material. The primer is applied to ensure that the adhesive layer will remain in place on the backing when the roll is unwound and later when the tape is removed from the surface to which it has been applied. Nitrile rubber, chlorinated rubber, and acrylates are currently used as primers for rubber-based PSAs. Acrylic PSAs do not generally require a primer coat.

The cracked panel is repaired with the different composite patches as shown in Figure 5. Araldite 2011 consists of two-component epoxy (mixing ratio of 100:80 by weight) is used as an adhesive to bond the patch on the cracked panel. The properties of Araldite 2011 are: Elastic modulus E = 1.16 GPa, and Poisson’s ratio ν = 0.4, shear modulus = 0.4 GPa, mass density = 1.20 g/cm3.[25,26] The justification for selection of Araldite 2011 amongst other structural adhesive is presented in section 6.4. Adhesive layer of uniform thickness was applied over the abraded area of the aluminum skin and the composite patch. The patch and aluminum specimen were precisely matched and aligned at the already marked location. The specimen bonded with the patch was cured at room temperature. The release agent was drained out after 1 hour of the adhesive application by removing the pressure sensitive tape.
