Henkel Launches New Fast Cure Silicone Ideal for Added Stability within Harsh Environments

Apr 22, 2008

To offer added protection and stability for a wide range of electronics applications, Henkel has developed and made commercially available Loctite� 5210�, a new fast cure thixotropic silicone material ideal for devices that find end-use within harsh environments. With improved production throughput, operating temperature flexibility and easy storage, Loctite 5210 offers manufacturers a cost-effective alternative to traditional hot-melt glues or less aesthetically pleasing silicones.

In particularly stressful end-use environments such as control boards, connectors, automotive modules and construction equipment, additional stability is often required to avoid device damage or system failure. Common damage seen in these types of environments may include bent leads, non- functional components due to vibration or material degradation. Henkel�s Loctite 5210 helps protect against these adverse occurrences. Unlike hot-melt glues which are often used for these applications but can be messy and hazardous in production environment, Loctite 5210 offers manufacturers an automated, safe and easy to use product while delivering considerable performance benefits as compared to competitive materials.

"This new silicone system is a vast improvement over hot melt glues,� states Tara Cary, Henkel Global Product Manager for circuit board protection materials. "Not only can glues be harmful and messy, they may also pose corrosion issues due to their high ionic content and, when used in high temperature environments, can actually melt and flow away. Either of these conditions could result in device failure. With Loctite 5210, application is clean and simple and material integrity is maintained.�

Loctite 5210 is an ultra fast curing, non-corrosive room temperature vulcanization (RTV) silicone material that has been designed for a variety of uses including wire tacking, selective sealing, vibration dampening and rework/repair applications on printed circuit boards (PCBs). With extremely fast dispense times � as little as 31 seconds for two connectors � and a tack free time of less than 5 minutes, Loctite 5210 offers manufacturers a high UPH alternative to other materials. It is also highly thixotropic, so the material will hold its form upon dispense and will not spread or migrate to other locations where the material is not desired. The silicone system cures at room temperature so no additional equipment investment is required to quickly integrate Loctite 5210 into the production environment.
