Adhesives for Hard-to-Bond Surfaces

When considering which adhesive to use for any bonding application, the choice of substrate is a critical factor. Often low surface energy materials are the best choice for the device. In our piece explaining what is surface energy and how it impacts adhesion we explained why substrates with low surface energy (LSE), like polypropylene (PP) and polyethylene (PE), are difficult to bond to.

3M^tm 300LSE range provides an easy and elegant solution to bonding LSE materials, powder coatings and oily metals quickly, invisibly and permanently.

These tapes bond plastic to rubber or metal and even foam to chrome.

3M^tm 300LSE range does not require using a primer and has high initial bond strength and high shear strength. These adhesives perform great on flat and curved surfaces alike. In addition, 3M^tm 300LSE range comes with a strong resistance to harsh chemicals and moisture.

Starting from just 0.05mm total tape thickness, these tapes are an ideal solution for product designers and engineers requiring bonding of plastics in a thin profile, low weight end product.

Some of the potential uses for the 3M^tm 300LSE range are:

• Lens bonding
• Gasket attachment
• Decorative trim attachment
• Nameplates and rating plates for hard to bond surfaces
• Plastic housing and component assembly
• Die-cut parts including LCD windows.
