What are the applications of HEMC in mortar?

Hydroxyethyl methyl cellulose is a non-ionic polymer in the form of white or off-white powder. It has many models and can be used in many kinds of mortars.

◆Cement-based plaster

1. Improve the uniformity, making the plaster mortar easier to apply and improving the resistance to sagging. Enhances flow and pumpability for increased productivity.

2. High water retention extends the open time of mortar, improves work efficiency, and helps the mortar to develop high strength during the solidification period.

3. Control the infiltration of air, thereby eliminating micro-cracks in the coating and forming an ideal smooth surface.

◆Gypsum plaster and gypsum products

1. Improve the uniformity, making the plaster mortar easier to apply, while improving the ability to resist sag and enhance fluidity and pumpability. Thereby improving work efficiency.

2. High water retention, extending the open time of mortar and producing high mechanical strength during solidification.

3. Form a high-quality surface coating by controlling the consistency of the mortar to be uniform.

◆Masonry mortar

1. Enhance the adhesion to the masonry surface and enhance water retention, thereby improving the strength of the mortar.

2. Improve lubricity and plasticity to improve construction performance. Using “Kundu brand” cellulose ether-reinforced mortar makes it easier to apply, saves time, and improves cost-effectiveness.

3. Special models with high water retention are available, suitable for bricks with high water absorption.

◆Joint filler

1. Excellent water retention, which can extend the open time and improve work efficiency. High lubricity makes application easier and smoother.

2. Improve shrinkage resistance and crack resistance, and improve surface quality.

3. Provides a smooth and uniform texture, and makes the joint surface more adhesive.

◆Tile adhesive

1. Make the dry mix mortar easy to mix without producing clumps, thus saving working time, improving workability and reducing costs due to faster and more effective application.

2. By extending the open time, the tiling efficiency is improved. Provides excellent adhesion.

3. Specially developed models with high slip resistance are available.

◆Self-leveling compounds

1. Provide viscosity and can be used as an anti-sedimentation additive.

2. Enhance fluidity and pumpability, thereby improving the efficiency of paving the floor.

3. High water retention, thereby greatly reducing cracking and shrinkage.

◆Extruded concrete panels

1. Enhance the processability of extruded products, with high bonding strength and lubricity.

2. Improve wet strength and adhesion of sheets after extrusion.
