METHOCEL™ 311 is a designed grade for solvent blend systems when viscosity and cling are required. It can be used as a thickener, rheology modifier, binder, lubricant, and film former. It is most commonly used in paint strippers and graffiti removers but it can also be used in industrial cleaners, adhesives, gel fuels, coatings, inks, and many other applications.

  • Adhesives: METHOCEL™ 311 functions as film former, thickener and binders in adhesives. It provides wet-tack, quick set, fast dry, and oil resistance to various types of adhesives.

  • Cleaning Solutions: METHOCEL™ 311 provides improved thickening, viscosity control, soil anti-redeposition, emulsion stabilization to cleaners and detergents.

  • Coatings and Inks: METHOCEL™ 311 is used as thickener, protective colloid, and pigment suspension in coatings and inks. It provides outstanding film properties such as high tensile, strength, and elongation. It also improves workability and water retention for construction coatings.

  • Paint Strippers: METHOCEL™ 311 is the ideal thickener for paint strippers due to its water and organic solvents solubility. It provides improved thickening and excellent cling for enhanced efficiency on vertical and inclined surfaces.

METHOCEL™ Efficient and Versatile - the Twin faces of a Market Leader

METHOCEL™ cellulose ethers include methylcellulose (MC) or hydroxypropyl methylcellulose (HPMC) polymers with solubilities ranging from water-soluble to organosoluble. METHOCEL ™ is an excellent rheology modifier, binder, film former, and water-retention agent. In addition, it has a few stand-out qualities. METHOCEL™ does not need hot water to dissolve; it is highly soluble in cold water. Therefore, energy can be conserved in dissolving the product. Another stand-out quality of METHOCEL™ is that once it is gelled by heat, it is able to revert back to liquid form when cooling. Many other thickeners do not have that flexibility.
