The story:
A large meter company in the South used Royal 423000/52300 high performance epoxy to bond and pot wiring interface with the electronic water meter housing. The previous epoxy was not developing good adhesion to the wire insulation and the new solution….
| What is the application? | Bonding / potting antenna wiring at the interface where it is inserted into the main body of the meter housing containing the PCB and LCD read-out |
| What issues was the end-user having? | Previous epoxy was not developing good adhesion to wire insulation, therefore moisture intrusion was occuring. |
| What material was used to solve the issue? | Royal 42300/52300 high performance epoxy with built in adhesion promoter to allow more aggressive adhesion to difficult to bond rubber or plastic substrates |
| Why was the material chosen for the application? | Developed substrate failure (wire insulation tore rather than gapped or separated from potting) when cured, therefore did not allow any leak paths within the interface |
| Why did this material work better than other materials? | This material was originally developed by Royal for a leading heavy equipment mfr’s wire harnesses where insulation was tephlon and needed high adhesion to wire insulation so no leak paths could occur |
| Was this material lower cost than other materials? | No, somewhat higher in cost, but not dramatically. It’s a repack by Extreme and runs about 30% higher |
| Did this material improve the process? | No process improvement, in fact added an extra step. However, it ensured no leaks over the 10 year warranty period. |
| Savings to end user in cost of material or process improvement? Time, $ or both? | Reduced rejects from 25% to less than 2%. This was the real savings to the customer, fewer warranty claims and little re-work or expenditures for field replacement |
| What industry/market was this material used in? | Remote wireless electronic water meters. |
