Elementis Deqian NUOSPERSE W-30 Wetting Agent – Frequently Asked Questions (FAQ)

Q1: What types of pigment systems is NUOSPERSE W-30 especially effective for?

A: NUOSPERSE W-30 is particularly effective for dispersing inorganic pigments such as titanium dioxide and iron oxides, as well as many organic pigments commonly used in waterborne architectural coatings, industrial finishes, and ink formulations. Its molecular structure supports strong anchoring and steric stabilization in aqueous media.

Q2: How does NUOSPERSE W-30 improve substrate wetting in water-based coatings?

A: As a low-foaming, anionic surfactant-based wetting agent, NUOSPERSE W-30 rapidly reduces surface tension at the liquid–substrate interface, promoting uniform film formation and enhancing coverage on low-energy or difficult-to-wet surfaces such as plastics, treated metals, and dusty concrete.

Q3: Can NUOSPERSE W-30 be used in combination with other dispersants or rheology modifiers?

A: Yes — NUOSPERSE W-30 is generally compatible with common polymeric and polyphosphate dispersants, as well as associative and non-associative thickeners used in waterborne systems. Compatibility should be verified experimentally within the final formulation due to potential interactions with cationic additives or high electrolyte content.

Q4: What is the recommended addition stage during manufacturing?

A: For optimal performance, NUOSPERSE W-30 is typically added during the let-down phase — after pigment grinding — to maximize its wetting and deagglomeration effects without interfering with the milling process. It may also be included early in the grind if improved initial wetting is required, depending on the specific equipment and formulation design.
