Why It Matters
Manufacturers protect steel and yellow-metal parts in storage, transit and overseas export without an oil film by using VCI actives, papers, emitters and bag concentrate. Procurement intent is strong, with buyers sourcing actives by case and drum
Solution Approach
Manufacturers protect steel and yellow-metal parts in storage, transit and overseas export without an oil film by using VCI actives, papers, emitters and bag concentrate. Procurement intent is strong, with buyers sourcing actives by case and drum 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.
