The first post in this blog series, based on key learnings from our Structural Adhesives 101 webinar, focused on the fundamentals of structural adhesives and common terms related to adhesives. Now that you know the basics, it’s time to consider which adhesive is ideal for your application.
When it comes time to determine the best fastening method, the debate is often over whether to use adhesives or weld. Structural adhesives offer many advantages over mechanical fastening methods, in industries ranging from automotive, signage, and construction.
Finding the perfect adhesives for your manufacturing needs can be a hassle. Determine the perfect bead length and diameter, choose a product by chemistry or application and review the different packaging sizes available and other accessories needed.
Looking for frequently asked questions about structural adhesives? You've found the right place. Our technical support teams, scientists, and application engineers have developed a comprehensive list of answers to some of the top questions we get asked.
Want to know how to use structural adhesives? Traditional welding and rivets are a time of the past. Our structural adhesives hold up against welding and other mechanical fasteners. Watch how our adhesives stand up to welding and how to use them.
