Paint remover grade of Hydroxypropyl Methylcellulose (HPMC) thickener with medium substitution. Yields viscosity of 4,000 cP at low addition levels.


Product Overview

METHOCEL™ F4M PRG is a water-soluble cellulose ether polymer with similar properties as METHOCEL™ F4M, except the grade is optimized for paint stripper applications. The product provides a viscosity of 4000 cP at low addition levels.


METHOCEL™ F4M PRG is designed for optimum performance in blended solvents systems such as paint strippers and removers. The product exhibits unique combination of water and organic solubility. It provides excellent thickening with shear thinning characteristics that improves contact time on vertical surfaces. METHOCEL™ F4M PRG can be used in paint strippers, cleaning solutions, and solvent based coatings and inks.

  • Cleaning Solutions: METHOCEL™ F4M PRG provides improved thickening, viscosity control, soil anti-redeposition, emulsion stabilization to cleaners and detergents. 

  • Coatings and Inks: METHOCEL™ F4M PRG functions as thickener, protective colloid, and pigment suspension aid in coatings and inks. It improves film formation properties such as high tensile, strength, and elongation.
