PROBLEM
A manufacturer of industrial control systems needed a potting solution to protect sensitive electronic circuit boards installed in manufacturing facilities with harsh environments. Their products were routinely exposed to high humidity, occasional water splashes, chemical vapors, and constant vibration. Standard potting compounds they had tested were proving inadequate – some provided good moisture protection but cracked under vibration, while others had good mechanical properties but allowed moisture ingress over time. Field failures were increasing, damaging their reputation and creating costly warranty claims. They had approached several large adhesive manufacturers, but their annual volume requirements of approximately 400 gallons fell well below the minimum threshold those companies required for custom formulation services.
SOLUTION
Advanced Bonding Technology conducted a comprehensive assessment of the specific environmental challenges facing the control systems. Our technical team analyzed the circuit boards and enclosure designs to identify optimal potting requirements. We developed a custom polyurethane potting compound with precisely engineered flow characteristics to fully encapsulate complex components without air entrapment. The formulation featured enhanced moisture resistance combined with mechanical flexibility to withstand constant vibration. We performed accelerated environmental testing, subjecting the potted circuits to temperature cycling, high humidity, and simulated vibration to validate long-term performance. Through multiple iterations, we refined the formula until it exceeded all performance requirements while maintaining processing characteristics compatible with their existing manufacturing equipment.
RESULTS
The custom potting solution completely eliminated moisture-related failures, which had previously accounted for 65% of warranty claims. The manufacturer’s field failure rate dropped from 4.2% to 0.3% within the first year of implementation. They now incorporate our specialized potting compound into all their industrial control products, ordering the compound on a monthly basis. We maintain continuous inventory to align with their production schedule, ensuring they never experience supply disruptions. Their warranty costs have decreased by 78%, resulting in significant cost savings and improved profitability. The enhanced product reliability has allowed them to expand into more demanding industrial environments previously considered too harsh for their systems, opening new market opportunities and contributing to 35% year-over-year growth.
