Reasons and advantages of using HEMC (hydroxyethyl methylcellulose) in tile adhesives

Environmental protection: HEMC is derived from cellulose, a natural polymer in plant cell walls, and is an environmentally friendly additive.

Thickening and water retention: HEMC acts as a thickener and water retention agent, affecting the consistency and workability of the adhesive mixture, enhancing the bonding properties of the adhesive, and providing the strength required to firmly fix the tiles.

Anti-drip: HEMC can improve the anti-drip properties of cement and gypsum mortar, reduce waste and improve work efficiency.

Adjust viscosity: HEMC is able to adjust the viscosity of liquid mixtures, which is very important for the preparation of building materials such as coatings, cement slurries and concrete.

Water retention: HEMC improves the water retention of building materials, helps to extend the working time of concrete and mortar, reduce the early drying rate, and improve quality.

Stability: HEMC has good stability under different temperature and humidity conditions and is suitable for various climatic conditions.

Comparison with HPMC: HEMC has better water retention than HPMC, especially in dry or hot conditions, tile adhesives containing HEMC can maintain a longer working time.

Flexibility: While HPMC is slightly more flexible and suitable for applications that need to withstand slight structural movement, HEMC is known for its excellent thickening ability and is ideal for achieving the desired consistency of tile adhesive mixtures.

Application scenarios: HEMC is suitable for a variety of tile adhesive applications, including bathroom remodels, kitchen background walls, outdoor patios and large commercial projects.

Safety: HEMC is a safe and environmentally friendly additive that does not harm indoor air quality and is suitable for a variety of indoor tile laying projects.

Mixing: HEMC can be mixed with other additives to obtain specific performance characteristics, but it is important to follow the manufacturer's guidelines and perform compatibility testing.

Shelf life: The shelf life of tile adhesives containing HEMC varies depending on the manufacturer and storage conditions. Generally, sealed containers can be stored for 12 months.

HEMC has become an indispensable multifunctional additive in tile adhesives due to its excellent water retention, thickening and bonding properties.
