Choosing an Anaerobic Thread Sealant
There are three basic types of thread sealants for metal pipe; pipe dope, PTFE (ex. Teflon®) tape, and anaerobic sealants. Anaerobic sealants are often chosen due to the limitations of dope and tape. Pipe dope is inexpensive and easy to use; however, it is solvent-based, which means it shrinks, hardens, and can crack over time. […]
Permabond Thermally Conductive EV Battery Adhesive Filler in the News
Permabond’s patent-pending technology for thermally conductive, expandable battery adhesive filler is getting some attention in the technology magazines on both sides of the pond. Recently ASI (Adhesives and Sealants Industry) and E-Motec (E-Mobility Technology International) have published articles on Permabond’s patent-pending technology. There aren’t often headlines about EV glue, so why is this new glue […]
Gasketmakers
Necessity is the mother of invention! In recent times, shortages of the most random items have brought out the creativity in all of us. Tissues substitute for toilet paper and canned tuna substitutes for cat food. But when those custom cut gaskets are out of stock or stranded in some far-off port what’s an engineer […]
High Temperature Resistant Cyanoacrylate
Permabond introduces new high temperature resistant cyanoacrylate adhesives! PERMABOND® 825 is a low viscosity cyanoacrylate adhesive that provides higher strength at high temperatures. Additionally, this fast-setting cyanoacrylate bonds metals, rubbers, plastics, and more. In fact, Permabond 825 resists up to 392°F (200°C) and has excellent retention of strength during thermal aging. PATENTED TECHNOLOGY Features and […]
Adhesives for Electric Vehicle Batteries
What are the biggest challenges in developing adhesives for electric vehicle batteries and the e-mobility market in general? I have to say it is balancing features. Many of the adhesive features battery manufacturers require play off each other. Following is a partial list of commonly requested features: Low Weight – Expandable adhesive products Good Heat […]
How to remove cyanoacrylate adhesive?
As we discussed here, there are three basic ways to remove adhesive. Mainly, dissolving, heating, and stress. To remove cyanoacrylate adhesive most effectively, a combination of all three ways may be used. The deciding factors on which is most appropriate are: What are the surfaces bonded? How much time do you have? On many surfaces, […]
What is the best glue for rubber?
Permabond 105 is an instant adhesive that bonds most types of rubbers, including Butyl, EPDM, Natural, and Nitrile. It forms strong bonds in seconds, and the strength continues to increase for 24 hours. For silicone rubber, use Permabond POP primer before bonding with Permabond. Cyanoacrylates, like Permabond 105, are commonly used to bond rubber. Although […]
What are the best plastic to metal adhesives?
Permabond is often asked, “What is the best glue for metal to plastic?”. It is a tough question – it is like asking what is the BEST flavor of ice cream? As we discuss here, there are metal adhesives that bond some plastics and plastic adhesives that bond some metals. The BEST option is dependent […]
How to bond acrylic to stainless steel
Various adhesive types, including UV curable, structural adhesive, and cyanoacrylate bond acrylic to stainless steel. Each type has its own characteristics. Adhesive Types that Bond Acrylic to Stainless Steel Include: UV Curable Permabond UV632 has superb adhesion to acrylic and many other plastics. It also forms strong bonds to metals. It bonds acrylic to stainless […]
UL® Classification of Pipe Sealants (thread sealants)
UL® performs various tests to determine the suitability of pipe sealants for a particular use. The UL® classification does not state the strength of the product or the maximum sealing pressure for other uses. For example, Permabond LH050 is classified by Underwriters Laboratories Inc.® for use in devices handling gasoline, petroleum oils, and natural gas […]
