Solvay Sipomer IBOMA HP Thickener – Frequently Asked Questions (FAQ)
Q1: What is the primary function of Solvay Sipomer IBOMA HP Thickener in aqueous formulations?
A: Solvay Sipomer IBOMA HP Thickener is a hydrophobically modified alkali-swellable emulsion (HASE) polymer designed to provide efficient rheology control and viscosity build in water-based systems. It delivers high mid-shear viscosity, good flow leveling, and enhanced sag resistance without significantly increasing low-shear viscosity.
Q2: How does this thickener perform in high-pH environments, and what pH range is recommended for optimal activation?
A: As an alkali-swellable thickener, Sipomer IBOMA HP requires neutralization with alkaline agents (e.g., AMP-95, NaOH, or TEA) to fully develop its thickening efficiency. It performs reliably in pH-adjusted systems typically ranging from 7.5 to 9.5, with full viscosity development generally achieved above pH 8.0.
Q3: Is Solvay Sipomer IBOMA HP Thickener compatible with common surfactants and co-thickeners used in architectural coatings?
A: Yes — it exhibits broad compatibility with nonionic and anionic surfactants, as well as with associative thickeners such as HEUR and HEC types. Compatibility should be verified in final formulations, particularly when blending with high-HLB surfactants or strong electrolytes, which may influence viscosity stability.
Q4: How should Solvay Sipomer IBOMA HP Thickener be incorporated into a formulation to ensure consistent performance?
A: It is recommended to add the thickener post-emulsification, after pH adjustment, under moderate agitation. Pre-dilution with deionized water (1:1 to 1:3) may improve dispersion. Avoid direct addition to highly acidic or unneutralized systems, as premature swelling can lead to inhomogeneity or gel particles.
