The product is hygroscopic. White mhlc, Sachtolith white pigment for aSachtolithPigment. The product should be stored under dry and clean conditions in its original packing and away from cilminal. Water retention Thickening and stabilizing action Binding ability Adhesion Protective colloid Suspension effect Emulsion stabilization Film formation Thermogelling properties Applications and Usage Notes Culminal methylcellulose derivatives are easily soluble in cold water.
Rotational Rheometry How to measure Shear Typical Product Specifications Chemically, Culminal products are ethers of cellulose and methylchloride, ethylene oxide or propylene oxide.
Agitate continuously until the powder has completely dissolved. Discontinue agitation once the polymer particles begin to swell. Culminal and Combizell methylcellulose derivatives are especially suited for tempera formulations, common in southern Europe because of their ideal compatibility with Bianco Meudon calcium carbonate extenders. Trademark, Ashland or its subsidiaries, registered in various countries. These cellulose derivatives have been designated as follows: Understanding Rheology of Thermoplastic Polymers www.
Both products provide water retention and cohesiveness to mixtures. After the powder is dispersed, add cool water to reach the final amount of solution needed. Table of contentsTableContentsDupontExtrusion.

ViscosityRheologyOf rheology. When reaching the gel temperature gelling and flocculation of the polymer will occur. This process is reversible upon cooling. Key Attributes Culminal cellulose ethers have many functional properties such as: To facilitate processing, Culminal and ,hpc products are available with retarded hydration and in four particle size ranges. Rotational Rheometry How to measure Shear Viscosity correctly? Culminal and Combizell methylcellulose derivatives include MC and HPMC chemistries and are used to control in-can consistency and storage stability of interior and exterior flat emulsion paints.
Culminal methylcellulose derivatives are culminao cellulose ethers and are compatible with many surfactants and polymers such as starch, guar and alginates. InformationProductsDupontRheologyProduct information.

Registered trademark, Ashland or its subsidiaries, registered in various countries. This type of machine is referred to as a plasticating jhpc. Culminal and Combizell methylcellulose derivatives have applications in external insulation and finishing systems EIFSgypsum plaster, joint compound, renders and stucco, self-leveling underlayments and floor screeds, skim coats, tile adhesives, caulks and sealants, tile cement and waterborne architectural coatings.
The product is not soluble in hot water. Introduction and Troubleshooting stream process operation. Compared to other cellulose ether chemistries, the methylcellulose derivatives have a slightly more Newtonian flow characteristic which provides increased high-shear ICI viscosity. Introduction and … www. Culminal products are powders used as thickeners, protective colloids, stabilizers, suspending aids and water-retention agents in many industrial applications.
