Technical Specifications and Parameters

Understanding the technical specifications of Hemc/Hec/Hpmc Hydroxy Ethyl Cellulose Hec 100000 Hydroxyethylcellulose Hec fun Kun is crucial for formulators to achieve desired paint properties. Hydroxyethyl Cellulose (HEC) is a non-ionic cellulose ether derived from natural cellulose through a series of chemical reactions. Its primary function in paints is as a thickener, protective colloid, and rheology modifier. The '100000' in the product name typically denotes a specific viscosity grade, usually indicating a solution viscosity of approximately 100,000 mPa·s (cP) for a 2% aqueous solution at 25°C, measured by a Brookfield viscometer. This high viscosity grade is particularly suitable for applications requiring significant thickening power and excellent sag resistance.

Key parameters include:

• Viscosity (mPa·s): A critical determinant of thickening efficiency. Grades vary widely, with 100,000 mPa·s indicating a high-viscosity type. This influences paint flow, leveling, and sag resistance.
• Degree of Molar Substitution (MS): Represents the average number of hydroxyethyl groups attached per anhydroglucose unit. An optimal MS value (typically 1.5-2.5) ensures good solubility and rheological properties.
• pH Value: Generally neutral (6.0-8.0 for a 2% solution), ensuring compatibility with a wide range of paint components and stability of the final formulation.
• Particle Size: Influences dissolution rate. Finer powders dissolve faster but can be prone to clumping if not properly dispersed. Common grades are 98% passing through 80 mesh.
• Moisture Content (%): Typically below 6%, crucial for product stability and prevention of microbial growth during storage.
• Ash Content (%): An indicator of purity, generally kept below 3-5% for high-quality grades.
