Frequently Asked Questions
What does "100% Solid Content" mean for these products?
100% solid content means the product contains no water or solvent carriers — it is a pure active substance. This ensures maximum efficiency per unit volume and eliminates dilution-related performance variability in your application system.
What is the difference between products with a pH range of 4.0–9.0 and those with 6.0–8.0?
Products with a wider pH range (4.0–9.0) offer greater flexibility and can be used across more acidic or alkaline environments, while those rated 6.0–8.0 are optimized for near-neutral systems where tighter pH control is maintained.
Which product grade is suitable for high-temperature processing applications?
The yellowish to light brown liquid grades (pH 5.0–9.0, viscosity 100–1000 cps) are specifically formulated for high-temperature processing environments and systems operating under extreme pH conditions, providing stable foam suppression under thermal stress.
How does viscosity range (300–600 cps vs. 100–1000 cps) affect product selection?
Lower viscosity grades (300–600 cps) are easier to pump and disperse quickly in lower-shear systems. Broader viscosity grades (100–1000 cps) provide more flexibility for varied processing conditions, including high-speed mixing or high-temperature environments where viscosity may shift.
Are these defoamers compatible with existing formulation systems?
Yes. All listed grades are designed for good compatibility with a wide range of application systems. The light yellow to colorless transparent liquid grades are particularly noted for strong compatibility and foam suppression performance across standard industrial formulations.
How should these products be stored to maintain their specification properties?
These products should be stored in sealed containers away from direct sunlight and extreme temperatures. Since they are 100% active content with no added solvents, maintaining proper storage conditions ensures the viscosity and pH performance remain within the specified ranges throughout the product's shelf life.
