Frequently Asked Questions
Q1
What does "100% Solid Content" mean for this product?
A solid content of 100% means the product contains no water or solvent — it is a pure, undiluted active substance. This ensures maximum efficiency and allows users to precisely control dosage without accounting for dilution factors.
Q2
What is the significance of the PH range (4.0–9.0 or 6.0–8.0) listed in the specification?
The pH range indicates the operating conditions under which the product performs optimally. Products with a wider pH range (4.0–9.0) offer greater versatility across acidic and alkaline systems, while those with a narrower range (6.0–8.0) are best suited for near-neutral environments.
Q3
What does viscosity (cps) indicate, and how does it affect application?
Viscosity (measured in centipoise, cps) describes the thickness or flow resistance of the liquid. Products with lower viscosity (e.g., 300–600 cps) are easier to pump and disperse, while higher viscosity variants (up to 1000 cps) may provide better film formation or surface adhesion in specific applications.
Q4
Which product variant is recommended for high-temperature processing?
The yellowish to light brown liquid variants are specifically formulated for use in high-temperature processing and in systems with extreme pH values. These grades offer enhanced thermal stability compared to the colorless/light yellow variants.
Q5
What does "strong foam suppression performance" mean in practical use?
Strong foam suppression (defoaming) means the product effectively reduces and prevents the formation of foam in industrial processes such as coatings, adhesives, paper manufacturing, and wastewater treatment — helping maintain process efficiency and product quality.
Q6
Are these products compatible with different application systems?
Yes. The light yellow to colorless transparent liquid variants are noted for good compatibility with a wide range of application systems. It is always recommended to conduct a small-scale compatibility test before full-scale use to ensure optimal performance in your specific formulation or process.
