    Frequently Asked Questions
    Q What is the solid content of these products?
    All listed product variants have a solid content of 100%, meaning they are supplied as pure, undiluted active substances without water or solvent carriers.
    Q What pH range do these defoamer products cover?
    The products cover a broad pH range. Some grades are suitable for pH 4.0–9.0, others for pH 6.0–8.0, and certain high-performance grades are effective across pH 5.0–9.0, making them adaptable for systems with extreme pH conditions.
    Q What viscosity range should I expect from these products?
    Viscosity varies by grade: lighter grades have a viscosity of 300–600 cps, while heavier or high-temperature grades fall in the 100–1000 cps range, offering flexibility for different processing equipment and application methods.
    Q Are these products compatible with different application systems?
    Yes. The colorless to light yellow liquid grades are specifically formulated for good compatibility with a wide range of application systems, delivering strong foam suppression performance without interfering with system chemistry.
    Q Which product grades are suitable for high-temperature processing?
    The yellowish to light brown liquid grades (pH 5.0–9.0, viscosity 100–1000 cps) are specifically designed for use in high-temperature processing environments and in systems that operate under extreme pH conditions.
    Q How do I select the right product grade for my application?
    Selection depends on your system's operating temperature, pH range, and compatibility requirements. For standard foam suppression at moderate pH, the colorless to light yellow grades are recommended. For high-temperature or extreme pH environments, the yellowish to light brown grades offer superior performance. Please contact us for tailored recommendations.
