Intertronics’ IRS 3071 potting compound is being used by Tough Tracker to protect the electronics within is electronic tracking product, which was designed to enable scrap bins such as skips to be located if they are lost or stolen.

The Tough Tracker was developed with a high-tech composite casing with a combination of a GPS satellite positioning system, a quad-band GSM transmitter with cell location function, anti-jamming technology and a three-axis accelerometer for ultra-sensitive motion detection.

Originally, a polyester potting compound was tried to protect the electronics, but its uneven cure led to exothermic hot spots and shrinkage, which caused component damage. While inexpensive, the polyester was hard and not sufficiently shock proof, shattering under impact testing.

Intertronics suggested that IRS 3071 be evaluated for the application. IRS 3071 is a semi-rigid, room-temperature-curing polyurethane resin system that is specifically designed for the cost-effective encapsulation of a variety of low- to medium-voltage electrical and electronic applications.

A custom metering, mixing and dispensing machine was also supplied by Intertronics.

Key benefits of product application

  • IRS 3071 is medium viscosity and flame retardant to UL94 V-0 at 6mm and it offers good adhesion to a range of substrates.
  • It is resistant to ultraviolet, water-based cleaning chemicals, motor oil, lubricants and most dilute acids and alkalis.
  • The potting compound is said to be crucial to the performance of the Tough Tracker and has been found to be waterproof, impact and thermally resistant and easy to work with.
  • Its electrical transmission characteristics allow the tracking signals, while its fire-retardant specification also helps with fire-proofing.
  • IRS 3071 works well in production, saving wastage of PCBs and enhancing performance in service
  • The custom metering, mixing and dispensing machine ensures efficient production and consistent performance.
  • The machine has allowed Tough Tracker to purchase bulk quantities of the potting compound, which has led to material savings.
