Culminal™ and Combizell™ methylcellulose derivatives

Detail by Market:

Culminal and Combizell methylcellulose (MC) derivatives help building materials apply more easily and perform better. Both products provide water retention and cohesiveness to mixtures. They are also used to control thickening, water demand, workability, sag resistance, strength and other important properties of the final product.

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. Compared to other cellulose ether chemistries, the methylcellulose derivatives have a slightly more Newtonian flow characteristic which provides increased high-shear (ICI) viscosity.

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. To facilitate processing, Culminal and Combizell products are available with retarded hydration and in four particle size ranges.

Culminal and Combizell methylcellulose derivatives have applications in external insulation and finishing systems (EIFS), gypsum 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.
