Product introduction

MHEC Powder

Hydroxyethyl Methyl Cellulose (HEMC), also known as Methyl Hydroxyethyl Cellulose (MHEC), is a non-ionic cellulose ether. It is made from natural polymer cellulose through a series of etherification reactions.HEMC has excellent water solubility, water retention, surface activity, thickening, film-forming, adhesion, suspension, high temperature resistance.... ...Mikem's products have been used in a wide variety of industries, including tile adhesives, grouts, putties/wall putties, cement plasters, gypsum-based products, and cement-based mortars.

MHEC Highlights 

Cold water solubility.HEMC dissolves easily in cold water, reducing your waiting time.

High Temperature Resistance. Typically stays working below 75°C.

Thickness. HEMC for liquids adds viscosity and stability. 

Water retention. Extended open time also helps cement hydrate more fully. lubrication.

Lubrication. HEMC used in cement improves ease and workability.

PH Stabilization: HEMC is stable in the pH range of 3-11.

HEMC is more stable in aqueous solutions.

Thermal gelation. Turns into a gel at high temperatures and turns back into a liquid when cooled.

Air-entraining. HEMC for mortar helps to increase mortar yield and improve compatibility.

Film formation: HEMC cellulose is water and oil repellent.

Water Retention: MHEC powder is an effective water retention agent. In construction materials like cement-based mortars and plasters, it helps to keep the mixture workable for longer periods. This is particularly useful in hot and dry climates where rapid moisture loss can hinder the application and curing process.

Improved Workability: When MHEC is added to cement-based mixes, it enhances their workability and consistency. This leads to smoother application, better adhesion, and reduced cracking, ultimately improving the quality of finished structures.

Improved Adhesion: MHEC powder acts as a thickening and bonding agent, promoting better adhesion of materials to various surfaces. This is crucial in applications like tile adhesives, where strong and long-lasting bonds are required.

Enhanced Slip Resistance: In tile adhesives and grouts, MHEC can improve slip resistance, ensuring that tiles remain securely in place even in wet environments.

Reduced Sagging: MHEC helps prevent sagging and slumping of construction materials, such as vertical wall coatings and renders. This ensures that the applied material stays in place as intended.

Improved Open Time: In construction and tiling applications, MHEC extends the open time of the adhesive or mortar. This allows workers more time to position tiles or work with the material before it begins to set.

Thickening and Stabilization: MHEC can act as a thickening and stabilizing agent in various formulations, including cosmetics. It helps maintain the desired consistency and texture of these products.

Improved Rheological Properties: MHEC can modify the flow properties of liquids, making it useful in applications like paints and coatings, where it helps achieve the desired viscosity and application characteristics.

Biodegradability: MHEC is generally considered biodegradable, which is an important consideration in environmentally conscious industries and applications.

Compatibility: MHEC is compatible with a wide range of other chemicals and additives, making it versatile for formulating products in different industries.
