Application of MHEC MH4M

KimaCell^® MHEC MH4M methyl hydroxyethyl cellulose plays a very important role in coatings and pastes. Only add the total amount of formula 0.2% to 0.5% can thicken, retain water, prevent pigments and fillers from settling, and increase adhesion and bonding strength.

• Viscosity The viscosity of cellulose ether aqueous solution changes with the shear force, and the coating and slurry thickened with cellulose ether also have this characteristic. For ease of application of the coating, the type and amount of cellulose ether must be carefully selected. For coatings, when using cellulose ether, medium viscosity products can be selected.

• Water-retaining cellulose ether can prevent water from quickly entering the porous substrate, so that it can form a uniform coating during the entire construction process without making it dry too quickly. When the content of the emulsion is high, the requirement of water retention can be met by using less cellulose ether. The water retention of paints and slurries depends on the concentration of cellulose ether and the coating substrate temperature.

• Stable pigments and fillers Pigments and fillers tend to precipitate. To keep the paint uniform and stable, the fillers of the pigments must be in a suspended state. The use of cellulose ether can make the paint have a certain viscosity, and no precipitation will occur during storage.

• Adhesion and bonding strength Due to the good water retention and adhesion of cellulose ether, good adhesion between the coating and the substrate can be guaranteed. MHEC has excellent dry adhesion and adhesion, so it is especially suitable for paper pulp.

• Protective colloid function Due to the hydrophilicity of cellulose ether, it can be used as a protective colloid for coatings.

• Thickener Cellulose ether is widely used in latex paint as a thickener to adjust the construction viscosity. Medium and high viscosity methyl hydroxyethyl cellulose is mainly used in emulsion paints. sometimes

• Cellulose ether can be used together with synthetic thickeners (such as polyacrylate, polyurethane, etc.) to improve some properties of latex paint and give latex paint uniform stability.
