The Challenge
A UK-based manufacturer of 32A/40A switching disconnectors required an adhesive solution to secure screw fastenings and prevent them from loosening due to vibration. However, their requirement was not straightforward. Because the screws were also used in continuity testing, traditional thread lockers couldn’t be used without risking isolation of the screw, leading to false readings.
Additional considerations included:
- The adhesive needed to be electrically conductive
- Application was in a blind area, where contact with electrical components couldn’t be ruled out
- The component couldn’t be heat-cured
- Precise control of quantity and cure time was essential for mass manufacturing
Following a web search, the customer contacted HITEK to establish the most suitable solution for their complex application.
Our Approach
HITEK promptly responded to the customer’s initial enquiry with a consultative and informed approach. Understanding the need for a precise, room-temperature curing solution, the team eliminated unsuitable options early on, significantly streamlining the product selection process.
Through close collaboration and technical expertise, HITEK was able to:
- Recommend various suitable solutions, while clearly explaining dispensing limitations and curing features.
- Work closely with Permabond to identify products that met the customer’s technical and budgetary requirements.
- Provide realistic cost breakdowns to ensure feasibility for high-volume production.
- Understand the specific application in detail and recommend dispensing methods to deliver the required level of accuracy.
Following multiple product evaluations and open discussions about performance and cost, Permabond 2010 was selected. Its thixotropic nature ensured it stayed in place and cured quickly when applied to screw heads, addressing the concern of the adhesive running into the isolator.
To further support cure speed, HITEK supplied Permabond CSA activator and an additional option, Permabond 2050, for trial—demonstrating proactive problem-solving and a commitment to ensuring the right solution has been provided.
The Outcome
Thanks to HITEK’s quick response, technical guidance, and supplier collaboration:
- The customer identified an effective, fast-curing adhesive that met both performance and cost criteria
- Trial results with Permabond 2010 and activator were successful, leading to an order for production use
- HITEK secured special project pricing through its strong relationship with Permabond, delivering added commercial value
“From the initial enquiry to finalising the solution, the team at HITEK were incredibly responsive and knowledgeable. They took the time to understand the complexities of our application and worked closely with us to trial several options, keeping performance and cost in mind.
Their technical insight, clear communication, and partnership with Permabond meant we were able to identify a product that not only worked perfectly for our needs but was also commercially viable for high-volume manufacturing. We’re very happy with the outcome and the support we received throughout the process.”
