Bermocoll EHEC and MEHEC cellulose ethers

Bermocoll® is a brand of cellulose ethers produced by AkzoNobel. Within the Bermocoll® product line, EHEC (ethyl hydroxyethyl cellulose) and MEHEC (methyl ethyl hydroxyethyl cellulose) are two specific types of cellulose ethers with distinct properties. Here’s an overview of each:

1. Bermocoll® EHEC (Ethyl Hydroxyethyl Cellulose):
   • Description: EHEC is a non-ionic, water-soluble cellulose ether derived from natural fibers through chemical modification.
   • Properties and Features:
     • Water Solubility: Like other cellulose ethers, Bermocoll® EHEC is soluble in water, contributing to its applicability in various formulations.
     • Thickening Agent: EHEC acts as a thickening agent, providing viscosity control in both aqueous and non-aqueous systems.
     • Stabilizer: It is used as a stabilizer in emulsions and suspensions, preventing the separation of components.
     • Film Formation: EHEC can form films, making it useful in coatings and adhesives.
2. Bermocoll® MEHEC (Methyl Ethyl Hydroxyethyl Cellulose):
   • Description: MEHEC is another cellulose ether with a different chemical composition, containing methyl and ethyl groups.
   • Properties and Features:
     • Water Solubility: MEHEC is water-soluble, allowing for easy incorporation into aqueous systems.
     • Thickening and Rheology Control: Similar to EHEC, MEHEC acts as a thickening agent and provides control over rheological properties in various formulations.
     • Adhesion: It contributes to adhesion in certain applications, making it suitable for use in adhesives and sealants.
     • Improved Water Retention: MEHEC can enhance water retention in formulations, which is particularly beneficial in construction materials.

Applications:

Both Bermocoll® EHEC and MEHEC find applications in various industries, including:

• Construction Industry: In mortars, plasters, tile adhesives, and other cement-based formulations to enhance workability, water retention, and adhesion.
• Paints and Coatings: In water-based paints to control viscosity, improve spatter resistance, and enhance film formation.
• Adhesives and Sealants: In adhesives to improve bonding and viscosity control.
• Personal Care Products: In cosmetics and personal care items for thickening and stabilization.
• Pharmaceuticals: In tablet coatings and formulations for controlled release.

It’s important to note that the specific grades and formulations of Bermocoll® EHEC and MEHEC may vary, and their selection depends on the requirements of the intended application. Manufacturers typically provide detailed technical data sheets and guidelines for the proper use of these cellulose ethers in various formulations.
