Choices abound when it comes to selecting a flexible magnet strip adhesive, including hot melt glues, wet glues, and rubber cement. But which option provides the most consistent, reliable results? The answers can be found in Adhesion of Flexible Magnet Strip: Application Best Practices and Choosing the Right PSA, a free whitepaper from Adams.
Flexible magnet sheets and strips are popular choices for signs and displays, because of their ease of use – bend them, twist them, print or paint on any message, and these durable solutions can be a great way to support any brand or promotion. But some form of adhesive may be necessary for many applications. As the whitepaper explains, pressure sensitive adhesives (PSAs) are often the most efficient and economical option. However, that still leaves the question of whether an acrylic or rubber-based PSA should be selected.
In addition to analyzing the pros and cons of acrylic and rubber-based PSAs, and the variables that determine which would be a better choice, the whitepaper covers other topics related to flexible magnet strip adhesion, including:
- Surface preparation: How to safely and effectively clean the magnet surface and remove any contaminants
- Surface contact: What is the best approach for optimal adhesion to smooth surfaces, rough surfaces, and mismatched surfaces?
- Lamination: Lamination removes entrapped air during the bonding process which can diminish adhesion.
