Ashland NATROSOL 250R TYPE Delayed Hydrolysis HEC Waterborne Thickener

Ashland NATROSOL 250R TYPE is a delayed hydrolysis hydroxyethyl cellulose (HEC) thickener designed for waterborne coatings and construction mortars. It delivers controlled viscosity development, excellent sag resistance, and superior storage stability without premature gelation. Compatible with high-shear systems and common additives, it ensures consistent rheology and easy incorporation. Ideal for architectural paints, tile adhesives, and grouts requiring balanced thickening performance.

Features Of Ashland NATROSOL 250R TYPE Delayed Hydrolysis HEC Waterborne Thickener

  1. Delayed hydrolysis profile enables controlled viscosity development during storage and processing.

  2. Excellent rheological performance with high pseudoplasticity and strong sag resistance in waterborne formulations.

  3. Enhanced compatibility with common co-thickeners, surfactants, and biocides used in architectural and industrial coatings.

  4. Low foaming characteristics support efficient high-shear mixing and spray application processes.

  5. Improved batch-to-batch consistency due to precise molecular weight control and narrow substitution distribution.

Typical Applications Of Ashland NATROSOL 250R TYPE Delayed Hydrolysis HEC Waterborne Thickener

  1. Interior and exterior architectural latex paints.

  2. Waterborne wood stains and clear finishes.

  3. Industrial maintenance coatings for metal and concrete substrates.

  4. Water-based adhesives and construction sealants.

  5. Decorative and functional wall coatings requiring long-term viscosity stability.
