EippponCell® MHEC LH 6200M, a methyl hydroxyethyl cellulose, is extensively utilized in the construction and paint industries. In the construction industry, MHEC serves multiple functions in building masonry and plastering mortar admixtures. It acts as a retarder, water retaining agent, thickener, and binder. It can also function as a dispersant and water retaining agent for plaster, mortar, and ground plaster used in gypsum-based and cement-based applications. MHEC is particularly valuable as a specialized admixture for aerated concrete blocks, enhancing the workability, water retention, and crack resistance of mortar while preventing cracking and hollowing of block walls. MHEC is also employed in the production of environmentally friendly building surface decoration materials. The process is straightforward and clean. It can be used for high-grade wall and stone tile surfaces, as well as for surface decoration of columns and monuments. MHEC can be formulated into ceramic tile grout, which exhibits strong cohesion, good deformation ability, no cracks or detachment, excellent waterproofing effects, vibrant colors, and outstanding decorative properties. In the paint industry, MHEC finds application as a stabilizer, thickener, and water retention agent in latex paints. It can also act as a dispersant, tackifier, and film-forming agent for colored cement paints. Adding cellulose ether of suitable specifications and viscosity to latex paint can improve its construction performance, prevent splashing, enhance storage stability, and increase hiding power. Cellulose ether products are often the preferred choice for latex paint thickeners. For instance, modified methyl hydroxyethyl cellulose ether possesses excellent overall properties, allowing it to maintain a leading position as a latex paint thickener. Furthermore, due to its unique thermal gel characteristics, solubility properties, good resistance to salt and heat, as well as appropriate surface activity, cellulose ether can serve as a water-retaining agent, suspending agent, emulsifier, film-forming agent, lubricant, adhesive, and rheology modifier.
