HEMC, a high-performance non-ionic cellulose ether for construction, appears as white powder and disperses quickly in cold water.
Notably, HEMC delivers excellent water retention and thickening properties, serving as a key additive for dry-mix mortar and putty.
This additive significantly improves construction fluency and durability, perfectly suiting residential, commercial and industrial buildings.

Specifically, core applications and effects cover three main scenarios:


First, wall putty. Adding HEMC greatly boosts putty adhesion and prevents peeling and powdering after application.
HEMC extends open time by 2-3 hours to facilitate easy leveling, creating a smooth putty layer without brush marks.
It further ensures tight bonding between putty and concrete, gypsum boards or other substrates.
Next, masonry/plastering mortar. HEMC optimizes mortar’s rheological properties and inhibits water-induced bleeding and segregation.
This additive reduces cracks, hollowing and peeling on hardened mortar walls, while enhancing compressive strength and interface adhesion.
Such optimized mortar fits both manual and mechanical construction seamlessly.
Finally, waterproof coatings. HEMC imparts good thixotropy and excellent anti-sagging on vertical surfaces.
The additive prevents coating accumulation and flowing during application, filling tiny pores after filming to strengthen water resistance.
This performance makes it suitable for roofs, kitchens, basements and other wet areas.

To maximize HEMC’s cost-effectiveness in construction projects, follow these tips:


Regarding selection, choose 50k-100k mPa·s HEMC for putty and 80k-150k mPa·s for waterproof coatings.
Furthermore, strictly control dosage between 0.2% and 0.5% of total materials.
Pre-mix HEMC with dry powders first, then add water and stir at 300-500r/min to avoid agglomeration.
In addition, combine with superplasticizers to reduce HEMC dosage by 10%-15%.Proper HEMC application guarantees material performance and construction quality.This proper use also minimizes raw material costs to the maximum extent.Moreover, HEMC meets green building demands for high-efficiency auxiliaries.The additive remains indispensable for wall decoration and waterproofing works.
