How to Bond Plastics to Metals and Alloys
How to bond plastics to metals is a common problem for design engineers. We hope the following tips are helpful. Bond Plastics to Metals Plastics The type of plastic is one of the major issues. Plastics like polyethylene and polypropylene can be hard work without preparation of surfaces. Permabond TA4605, TA4610, TA4630, and TA4631 bond […]
Materials, modes and methodologies for advanced engineering
Advanced adhesive materials are in demand to fill the need for improved, cheap, and better methods in modern engineering and materials science. New materials are coming on the market regularly, and to design engineers, these are always interesting developments. That said, all engineers tend to believe in wonder products after they’ve seen some proof. In […]
How to Understand Adhesive Lingo
Manufacturers and users of adhesives and sealants use certain words and phrases to explicitly describe characteristics and performance attributes. Like many industrial terms, the best results happen when the meaning of these terms is clear in the context of your application. You could be forgiven for thinking you were speaking another language. Technical jargon isn’t […]
Common Mistakes to Avoid When Using Anaerobic Adhesives
Anaerobic Adhesives Curing Tips Overall the best anaerobic adhesive tip is to ensure the anaerobic adhesive has the two things needed to cause a cure. Namely, contact with metal and no contact with oxygen. Tip #1 Anaerobic adhesive tip #1 Ensure contact with metal. Following are three examples of adding something between the anaerobic and […]
Fire Protection – Tape – Dope – Pipe sealant comparison.
Fire protection sealants prevent leaks in sprinkler systems. Leaking sprinkler systems can cause tens of thousands of dollars in damage to ceilings, floors, furnishing, and other valuables. Preventing these leaks is not an option for installers; it is a requirement. The metal pipe connections in sprinkler systems can be sealed with PTFE tape, pipe dope, […]
One Component Or Two?
When designing a manufacturing process with adhesives in mind, one of the first questions that arises is “Will the adhesive be one component or two?” (I.e. will it just be one liquid, or will there need to be two that are some how mixed together?). Often it is assumed that one part processes are more […]
The Relationship Between Air, Metal and Anaerobic Adhesive
Anaerobic adhesives cure when isolated from oxygen in the presence of metal ions, such as iron or copper. These adhesives are used in a variety of applications, including threadlocking, retaining, pipe sealing, and gasketing. The Air Metal Adhesive Relationship The relationship between the amount of air, metal, and adhesive/sealant is significant. See how it […]
Shipping regulations regarding certain kinds of adhesives
Because adhesives can be hazardous, toxic, or flammable, you should never ship any industrial grade adhesives without first taking the necessary steps to make sure you’re doing so safely, and legally. Because of the regulations, and especially with recent tightening of certain regulations, we advise that, if possible, you try to buy epoxy, adhesive, or […]
Green or Greenwashed – what’s the difference?
Around the globe, there is a growing emphasis on protecting our environment. Sometimes referred to as reducing the carbon footprint, this movement has resulted in an outpouring of products relabeled as green. Buyers are motivated by emotions and often will pay more money to support planet-friendly products and operations. The challenge for buyers is determining […]
How do I avoid stress cracks when bonding plastics?
Stress cracks occur when the short-term mechanical strength of a plastic is subjected to adverse forces. Careful design of compatible substrates and consistent manufacturing and assembly processes reduce or prevent stress cracks. Stress Cracking Causes There are several areas to consider when looking for the cause of stress cracks in plastic components. Manufacturing/Extruding/Molding processes Thermal […]
How do I prevent white powdery residue when using instant adhesives?
Frosting – Blooming – Chlorosis Whatever you call it, we all recognize chlorosis as the unattractive white stuff that can sometimes occur when using instant adhesives. The residue is a byproduct of the cure process of the adhesive. Once the monomer is in vapor form, it will react with moisture in the air, cure, and […]
Help! I’ve got air in the bond line!
The adhesive failure troubleshooting process begins with a thorough knowledge of the processes leading up to and including the application of the adhesive. There are many possible causes for failure of bonded components. Before suspecting air in the bond line as the source of failure, double-check the adhesive selection, the application process, and the working […]
