Methyl Hydroxyethyl Cellulose (MHEC) Chemical For ETICS/EIFS

The Role Of MHEC In EIFS/ETICS:

● Improved adhesion: The materials of the exterior walls are firmly held together by using this cellulose material.

● The adequate wetting ability for EPS board and substrate:HEMC/MHEC improves how effective the wetting of the board and substrate.

● Reduced air entrancement and water uptake: The air spaces within the external walls of buildings become resistant to the passage of air, which may weaken the structure. Water uptake is reduced as well, HEMC/MHEC increases the water retention of the walls and this does not allow water uptake.

● Good consistency: This cellulose allows the walls to maintain a consistent finish look and appearance, and this adds beauty to the walls.

● Good anti-bleeding:Cellulose Ether HEMC/MHEC prevents the occurrence of bleeding within the exterior walls

● Anti-crack and anti-shrinkage: The occurrence of wall cracks and shrinkages are prevented with the use of Hydroxyethyl Methyl Cellulose.

● Good workability: It also offers good workability. The designated particle size distribution assures quick or lumps free dissolution. It is suitable for all conventional mineral and organic binders.

Considerations for Using MHEC in EIFS/ETICS:

Proper Mixing: Ensure MHEC is thoroughly mixed with other dry components before adding water. This helps achieve a homogeneous mixture.

Optimal Water Ratio: Use the correct amount of water as specified in the formulation to ensure proper consistency and performance of the mixture. Too much or too little water can affect the workability and final properties of the material.

Surface Preparation: Ensure the substrate is clean, dry, and free of contaminants before applying the mixture. Proper surface preparation enhances adhesion and overall system performance.

Curing and Drying:Avoid rapid drying, which can lead to shrinkage and cracking. MHEC helps in water retention, but it is still important to protect the applied system from direct sunlight and strong winds during the initial curing period.
