3M’s Scotch-Weld Structural Adhesive technology opens the door to new design options. High shear and peel strength provide durability in the toughest environments, and production boosters save time, labor and overall cost. 3M’s Scotch-Weld Structural Adhesives work well with multiple substrates including plastics, metals, and composites without sacrificing performance properties. Even low surface energy plastics (such as thermoplastic polyolefin, polypropylene, and polyethylene, which in the past had to be mechanically attached or heat welded) can now be bonded with specialty structural adhesives.
Adhesive and Tape Solutions for Hard to Bond Materials
As engineers seek to design products that are durable, high quality, long lasting, but still affordable, they are turning increasingly to materials beyond traditional metals for components and assemblies. These alternate materials can include a wide range of plastics, composites and rubbers in multiple forms including molded parts and foams.
Innovations in Bonding to Low Surface Energy Surfaces
When seeking to manufacture a plastic-based part, there are more options for attaching parts together than ever before. In the past Low Surface Energy (LSE) plastics, such as Thermoplastic Polyolefin (TPO), Polypropylene (PP), and Polyethylenes (e.g. HDPE)) had to be mechanically attached or solvent welded since true adhesive bonding did not work well with these materials. Mechanical attachments (such as clips, screws, etc) can be used with virtually any surface but they require additional steps to mold or create features for the attachment, can lead to stress concentrations which may result in plastic cracking and premature failures, and often result in unsightly surfaces. Solvent welding has the disadvantage of relying on the use of hazardous and noxious solvents.
Outperforming Mechanical Fasteners: Using Structural Adhesives for Structural Applications
As times change and products become more sophisticated, manufacturing techniques must be refined to accommodate new needs in structural applications. Mechanical fasteners and welding are traditional joining methods that many manufacturers are comfortable with, however, these methods are not always the most practical solution for modern assembly. Mechanical fasteners can drive up costs, limit options for materials, and cause fatigue, metal distortion or tearing.
