Descripción

METHOCEL™ E10M is a medium molecular weight hydroxypropyl methylcellulose polymer with moderate degree of hydroxypropyl substitution.  It is used a as a thickener, binder, and film former in waterborne coatings, inks, adhesives, cleaners, and ceramics.  The hydroxypropyl substitution of METHOCEL™ E10M makes it compatible with alcohols and other polar organic solvents.  When added to water at 2% METHOCEL™ E10M yields solutions with a viscosity of 10,000 cps.

Usos

METHOCEL™ E10M is an industrial grade HPMC thickener that produces solutions with a high viscosity and thixotropic rheology.

Household & Industrial Cleaners:  METHOCEL™ E10M is used as a thickener for water-based and alcohol based formulations.  It has outstanding pH stability and can be used to provide stable viscosity to both acid and alkaline formulations.  METHOCEL™ E10M provides solutions with a thixotropic viscosity that allows them to be easy to dispense and spread while also maintaining cling to vertical surfaces.  Solutions of METHOCEL™ E10M have a soft lubricating feel and are non-tacky when dry.

Coatings, Inks, & Adhesives: METHOCEL™ E10M is used to thicken water-based coating, inks, and adhesive formulations.  It produces solutions that are easy to spread and with excellent cling to vertical surfaces.  METHOCEL™ E10M can also be used to form flexible films that are resistant to oils and grease.

Ceramics: METHOCEL™ E10M is used in ceramics as a temporary binder and lubricant.  When added to ceramic slurries METHOCEL™ E10M provides a thixotropic rheology that reduces the pressure necessary for ceramic extrusion.  Once extruded, ceramic parts containing METHOCEL™ E10M have remarkable green strength.  This is due to the thermal gellation property of HPMC.  METHOCEL™ E10M will reversibly gel at temperatures above 58°C to provide added green strength that reduces the risk of defects.  Once fired, the METHOCEL™ E10M burns out cleanly and you are left with a defect free ceramic part.
