Frequently Asked Questions
Q
What does "Solid Content 100%" mean in the product specification?
A solid content of 100% means the product is supplied in its pure, undiluted form with no added water or solvent. This allows for greater flexibility in dosage and formulation, as end users can dilute it according to their specific process requirements.
Q
What is the difference between the products with a pH range of 4.0–9.0 and those with 6.0–8.0?
Products with a broader pH range (4.0–9.0) offer greater versatility across acidic and alkaline systems. Those with a narrower range (6.0–8.0) are formulated for more neutral environments, providing optimized stability and performance in near-neutral application systems.
Q
What viscosity range is available, and how does it affect application?
The products are available in two viscosity ranges: 300–600 cps and 100–1000 cps. Lower viscosity grades are easier to handle and mix, while higher viscosity grades may provide better film formation and surface coverage in certain coating or processing applications.
Q
Which product variants are suitable for high-temperature processing?
The yellowish to light brown liquid variants are specifically designed for use in high-temperature processing environments and in systems with extreme pH values. These grades offer enhanced thermal stability and chemical resistance compared to the colorless or light yellow variants.
Q
What does "strong foam suppression performance" mean, and why is it important?
Strong foam suppression performance means the product effectively prevents or reduces unwanted foam formation during industrial processing. This is critical in applications such as coatings, adhesives, and chemical manufacturing, where excessive foam can disrupt production efficiency, affect product quality, and cause equipment issues.
Q
How should I select the right product grade for my application?
Selection depends on your system's pH environment, operating temperature, and required viscosity. For standard neutral-to-mildly-acidic or alkaline systems, the light yellow to colorless variants are recommended. For high-temperature or extreme pH environments, the yellowish to light brown grades are more appropriate. Please consult our technical team for a tailored recommendation.
