Why It Matters
Surfactant-rich spray tanks foam during agitation/filling, causing overflow, dosing error, and pump cavitation; need a defoamer that knocks down and suppresses foam
Solution Approach
Surfactant-rich spray tanks foam during agitation/filling, causing overflow, dosing error, and pump cavitation; need a defoamer that knocks down and suppresses foam 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 Application Workflow
1
Application & Agronomic Review
Define the use (crop input, adjuvant, soil amendment, post-harvest) and the agronomic, regulatory, and tank-mix requirements.
2
Input & Grade Selection
Match the surfactant or adjuvant, nutrient source, chelate, or formulation aid to the active, water quality, and label.
3
Compatibility & Rate Trial
Confirm tank-mix compatibility, dose, and stability, and size packaging (jugs, drums, totes, bulk) to the season and logistics.
4
Field Validation
Validate efficacy and crop safety in field trials, and lock the spec and supply plan for the season.
Recommended Chemistries (3)
EO/PO Block Copolymer (Demulsifier / Defoamer)
CAS 9003-11-6
Glycols & Polyols
Cleaning / Degreasing
EO/PO block copolymer has inverse (cloud-point) solubility: above its cloud point it phase-separates into the foam lamella, spreads, and ruptures the film - a genuine persistent non-silicone defoamer for surfactant-loaded spray tanks, unlike the merely transient alcohol knockdown
