Q1: What is the primary function of Croda Lissapol D POWDER in formulations?
A: Croda Lissapol D POWDER is a highly effective anionic wetting agent designed to rapidly reduce surface tension and promote uniform dispersion of pigments, fillers, and other solids in aqueous systems—particularly in dry-mix construction chemicals, tile adhesives, and grouts.
Q2: How does the powder form benefit manufacturing and handling compared to liquid alternatives?
A: As a free-flowing, low-dust powder, Lissapol D POWDER offers improved dosing accuracy, simplified logistics (no freezing or viscosity concerns), enhanced shelf-life stability, and easier integration into dry-blend production lines without requiring additional water or solvents.
Q3: Is Croda Lissapol D POWDER compatible with common cementitious and gypsum-based systems?
A: Yes—it demonstrates excellent compatibility with Portland cement, blended cements, calcium sulfate hemihydrate (gypsum), and typical admixture packages, including superplasticizers and redispersible polymer powders, without compromising setting behavior or early strength development.
Q4: What is the typical dosage range for optimal wetting performance?
A: Dosage depends on formulation requirements and desired performance level, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight of the total dry solids—to achieve effective substrate wetting and particle deagglomeration without excessive foaming.
