Q1: What is the primary function of Samsung SPB30K in formulations?
A: Samsung SPB30K is a hydroxyethyl cellulose (HEC) polymer designed primarily as a non-ionic rheology modifier. It provides effective viscosity enhancement, suspension stabilization, and improved water retention across aqueous systems—particularly in architectural coatings, tile adhesives, and construction mortars.
Q2: How does SPB30K differ from other HEC thickeners in terms of solubility and hydration behavior?
A: SPB30K is engineered for rapid, low-foam dispersion and efficient cold-water hydration, minimizing gel lumps during high-shear mixing. Its optimized particle size distribution and surface treatment support consistent performance in both batch and continuous manufacturing processes.
Q3: Is Samsung SPB30K compatible with common biocides and other additives used in water-based coatings?
A: Yes, SPB30K demonstrates broad compatibility with standard preservatives, defoamers, dispersants, and co-thickeners such as associative HEURs or xanthan gum. As with any formulation change, compatibility testing under actual use conditions is recommended to confirm stability and performance.
Q4: What are typical dosage ranges for SPB30K in construction-grade tile adhesives?
A: Dosage depends on formulation requirements and desired open time, sag resistance, and wet tack. In cementitious and dispersion-based tile adhesives, SPB30K is typically used at low concentrations—generally ranging from 0.1% to 2% by weight of the total formulation—to achieve balanced rheology without compromising setting behavior.
