Hydroxypropyl methylcellulose (HPMC) thickener with low substitution. Yields viscosity of 15,000 cP at low addition levels.


Product Overview

METHOCEL™ K15M is a water-soluble cellulose ether polymer. It is a low substitution hydroxypropyl methylcellulose (HPMC). The product provides a soft gel texture with a viscosity of 15,000 cP. METHOCEL™ K15M has the highest gelation temperature of 70°C - 90°C (158°F - 194°F).


METHOCEL™ K15M, featured with low substitution level, offers controlled thickening and soft gelling for higher temperature range applications. The product is widely used in ceramics, coatings, adhesives, and any other application when high gelation temperature is required.

  • Adhesives: METHOCEL™ K15M can be used in food contact adhesives. It functions as a film former, thickener, and binder in water-based formulations. It provides wet-tack, quick set, fast dry and oil resistance to various types of adhesives.

  • Ceramics: METHOCEL™ K15M functions as thickener, binder, and rheology modifier in ceramics, extrusion, and casting. It also provides lubricity, smoother surfaces and prevents sag or deformation.

  • Coatings: METHOCEL™ K15M provides an improved thickening and soft gelling in a wide range of coating applications. It also improves workability, stability, and water retention in formulations.
