Project Description
Defoamers for Cutting Fluid & Metal Working Fluids
Foam generation remains a persistent operational constraint within high-speed metal working fluids (MWF), cutting oils, and water-soluble grinding coolants. Rapid fluid recirculation, aggressive mechanical shear parameters across CNC spray nozzles, and the extraction of fine metallic swarf actively entrain systemic macro-air. Uncontrolled foam accumulation induces sump overflows, reduces chemical lubrication efficiency boundaries, prompts fluid maintenance degradation, and causes high-pressure pump cavitation boundaries.
INVINO® formulates technical silicone emulsions and specialized non-silicone organic compounds engineered for instantaneous bubble knockdown and prolonged dynamic persistence. Our anti-foaming additions maintain high stability profiles across severe high-temperature metal grinding, ensuring fluid longevity, maximizing tool service lifespan indices, and preventing interference with tramp oil skimming separation units.

Solving Foam Challenges in Machining & Grinding
The Failure Mode: Entrained gaseous matrices act as thermal insulators, preventing the synthetic cutting coolant fluid from properly mapping and cooling the workpiece interface boundary.
The Failure Mode: Excess surface micro-froth accumulation induces central sump fluid spills and overflows, causing machine downtime alarms and high-pressure pump cavitation hazards.
The Failure Mode: Air pocket distortions yield poor surface finish aesthetics, dimensional inaccuracy shifts on micro-machining tolerances, and accelerated degradation across fine filters.
The Failure Mode: Severe foam expansion patterns speed up additive depletion, causing premature emulsified base rancidity drifts and higher tank biocide replacement costs.

Q&A: Precision Control for Metalworking Fluids
Q: Will it affect downstream painting or plating (Silicone Spots / Cratering)?
A: Standard raw silicone oils separate under long storage, causing surface tension craters on parts. Our structural emulsions feature precise chemical dispersion, maintaining homogenous distribution to prevent post-machining wire coating defects or plating pinholes.
Q: Can it defoam "Fully Synthetic" grinding fluids?
A: Yes. Fully synthetic formulations carrying extreme surfactant boundaries generate highly stable foam. INVINO-M602 provides localized emulsion stability parameters to achieve flash foam collapse across transparent non-mineral fluid coolants.
Q: Is it stable under high-pressure CNC spraying?
A: Yes. High-speed fluid nozzles introduce acute shear stress that degrades regular emulsions into oil clots. INVINO-M780 utilizes cross-linked copolymer chains calculated to retain persistent anti-foaming kinematics throughout active cutting boundaries.
Q: Will the defoamer clog the fine filters?
A: No. Poorly suspended particles or heavy hydrophobic carriers gather slime that blinds paper filtration bands. Our fluid actives maintain particle dimensions well below standard micro-filtration requirements, facilitating uninterrupted flux.
Q: Does it interfere with Tramp Oil skimmers?
A: No. INVINO-M066 targets structural gas-liquid interfaces exclusively without creating chemical emulsion boundaries between the core coolant fluid matrix and leaked leakages, allowing unhindered skimming separator functionality.
