QUESTION: We want to bond aluminum to several thermoplastics and thermosets for an outdoor application that could experience both high and low temperatures. What types of adhesives should we consider?
Novel, all-acrylic pressure-sensitive adhesive compositions with inherently lower surface energy display significantly improved adhesion to LSE substrates such as polyethylene and polypropylene.
The prevailing trend toward the use of lighter weight and lower cost engineered plastics in automotive, construction, aerospace, electronics, and other industrial uses has created a need for pressure-sensitive materials that can bond well to these new, inherently low-surface-energy (LSE) plastics. This article discusses novel, all-acrylic compositions with inherently lower surface energy that display significantly improved adhesion to LSE substrates such as polyethylene and polypropylene.
Pressure-sensitive adhesives (PSAs) are used in applications ranging from labeling food packaging to assembling electronic devices to mounting graphics displays. Although they have been around for decades and their use is widespread, manufacturers, converters, and printers may not understand the key differences between the adhesive choices available, how they’re constructed, or which are best suited for a particular job.
