Potting Encapsulation — Process Challenge

Conformal Coatings & Potting/Encapsulation Resins

Electronics manufacturers protect PCBs from moisture, dust and vibration with conformal coatings and potting/encapsulation resins, sourcing both finished systems and raw materials. We already hold much of the raw-material spine in epoxy, silicone fluids and silanes
Why It Matters

Solution Approach

Electronics manufacturers protect PCBs from moisture, dust and vibration with conformal coatings and potting/encapsulation resins, sourcing both finished systems and raw materials. We already hold much of the raw-material spine in epoxy, silicone fluids and silanes RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Treatment Workflow
1
System Assessment
Characterize operating conditions—fluid composition, temperature, pressure, flow rates—and benchmark current treatment performance.
2
Chemistry Selection
Match base chemicals to your operating envelope. Factor in compatibility with existing programs, regulatory constraints, and downstream impacts.
3
Dosage & Delivery
Determine optimal treat rates through jar testing or field trials. Configure packaging (drums, totes, ISO tanks) to match consumption and storage logistics.
4
Monitoring & Adjustment
Track KPIs—coupon rates, residuals, separator performance, water quality. Adjust chemistry and dosage as conditions change.
