Low-Foam Surfactants for Spray & Parts Washers

Design controls foam in spray/ultrasonic equipment with low-foam nonionic surfactants and silicone defoamers
Why It Matters
Design controls foam in spray/ultrasonic equipment with low-foam nonionic surfactants and silicone defoamers
Solution Approach

Design controls foam in spray/ultrasonic equipment with low-foam nonionic surfactants and silicone defoamers 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.
