Product Description

Product Description

HEMC: The Superior Choice for Gypsum-Based Products

Hydroxyethyl Methyl Cellulose (HEMC) stands out as a high-performance additive for gypsum-based formulations, offering unmatched advantages in workability, water retention, and durability.

Key Benefits:

1.Enhanced Workability: HEMC improves plasticity and smooth application, ensuring optimal spreadability for gypsum plasters, mortars, and self-leveling compounds.
2.Superior Water Retention: Its unique molecular structure minimizes water loss, preventing premature drying and ensuring proper hydration of gypsum for maximum strength development.
3.Improved Adhesion & Crack Resistance: HEMC enhances bond strength to substrates while reducing shrinkage and microcracking, critical for long-term durability.
4.Stability & Consistency: Unlike conventional thickeners, HEMC maintains viscosity stability under varying temperatures and pH levels, ensuring reliable performance in diverse conditions.

Why Choose HEMC?

With its balanced rheology and compatibility with gypsum chemistry, HEMC delivers consistent quality, faster application, and reduced material waste—making it the ideal modifier for high-performance gypsum products.

Usage Guidelines

*Ensure the product is thoroughly pre-mixed with other dry powder components before packaging. On-site, mix and use according to the
specified water amount.

*The recommended dosage is 0.40%-0.60% of the cementitious material, but it is essential to conduct pre-testing based on raw materials and construction specifications prior to use. 

* Handling Instructions: Follow safety precautions such as wearing gloves and avoiding contact with eyes during handling.

Storage Condition

*Store the product in its original packaging in a dry, clean environment, away from heat sources. While this product is not prone to losing
efficacy, it is hydrophilic and may slowly absorb moisture if stored in poor conditions.
*It is recommended to use the first-in, first-out principle.
 *Ensure the packaging is tightly sealed to prevent moisture absorption if not fully used.

Product Safety

In accordance with legal regulations regarding hazardous materials, this product is considered non-hazardous. However, avoid the
formation and accumulation of dust. Any spillage should be swept up while keeping it dry, as contact with water may create a slipping
hazard. For further information, please contact us.
