Simplified Acrylic Thermosetting Adhesives (Honeymoon Application)

Adhesives Formulation

Applicable Base Polymer Properties

Thermosetting acrylic adhesives are rubber-toughened systems that cure rapidly at room temperature to provide a crosslinked structural adhesive suitable for bonding metals, engineering plastics, and many other substrates with minimal surface preparation. They provide a high tensile shear and peel strength, chemical resistance, and impact strength.

Resulting Properties

The cure of acrylic adhesives is initiated by a two-part redox reaction system. One component of the redox reaction is present in the base component of the adhesive, and the second component is present in the accelerator or “curing” component. Various tougheners have been used in thermosetting acrylic adhesives. A very common toughener is neoprene elastomer. In this simplified formulation, the B-side is only stable for about a day. This composition gives surprisingly good performance on a range of substrates.
