Q1: What types of formulations is SN-THICKENER 665T most commonly used in?
A: SN-THICKENER 665T is primarily designed for water-based industrial coatings, architectural paints, and construction mortars where controlled rheology and sag resistance are required. It performs well in both low- and medium-solids systems and is especially valued for its compatibility with common pigment dispersants and co-thickeners.
Q2: How does SN-THICKENER 665T differ from traditional associative thickeners?
A: Unlike many hydrophobically modified ethoxylated urethanes (HEUR), SN-THICKENER 665T offers enhanced tolerance to electrolytes and a more balanced viscosity profile—delivering good high-shear flow while maintaining low-shear structure. This supports improved application properties such as leveling and spatter resistance without excessive gel formation during storage.
Q3: What is the recommended addition method for optimal performance?
A: For best results, SN-THICKENER 665T should be added post-pigment dispersion, preferably under moderate agitation. Pre-dilution with water or a compatible solvent is advised to ensure uniform distribution. Avoid high-shear mixing immediately after addition to prevent premature network breakdown.
Q4: Is SN-THICKENER 665T compatible with biocides and pH adjusters commonly used in paint systems?
A: Yes, SN-THICKENER 665T demonstrates broad compatibility with standard isothiazolinone and formaldehyde-releasing biocides, as well as common pH adjusters like AMP-95™ and TEA. However, compatibility testing under actual formulation conditions is always recommended due to potential interactions with specific preservative chemistries or extreme pH shifts.
Q5: What is the typical dosage range for achieving target viscosity?
A: Dosage depends on formulation requirements, but SN-THICKENER 665T is typically used at low concentrations—generally ranging from 0.1% to 2% by weight of the total formulation—to achieve desired rheological performance without compromising other properties.
