What Is Mortar?

Mortar is a mixture of cement (or gypsum), sand, fillers, and functional additives used for bonding, leveling, repairing, and finishing construction surfaces.

Modern dry mix mortar relies heavily on specialty chemical additives to improve:

  • Workability
  • Water retention
  • Bonding strength
  • Flexibility
  • Crack resistance
  • Setting time control
  • Durability

Without proper additives, mortar performance cannot meet current construction standards.

General FAQs

Frequently Asked Questions Questions

Cellulose ether (HPMC) is essential, followed by RDP, superplasticizer, fiber, and performance modifiers depending on application type.

RDP improves adhesion, flexibility, impact resistance, and durability.

Yes, we provide application-based formulation optimization.

Yes, we cover bonding, plastering, repair, waterproof, self-leveling, and insulation mortars.

Proper dissolution is critical for HEC performance:

  1. Dispersion: Add HEC slowly to vortex of agitated water (not vice versa)
  2. Particle Size: Use fine mesh grades (80-100 mesh) for faster dissolution
  3. Temperature: Start with cold water (15-25°C); heat after hydration
  4. pH Adjustment: Add acids/bases only after full hydration
  5. Time: Allow 20-30 minutes for complete hydration

Pro Tip: Pre-dispersing in glycerol or alcohol prevents lumping in high-shear systems.

Hydroxyethyl Cellulose pricing depends on:

  • Viscosity grade: Higher viscosity = higher price
  • Purity level: Industrial vs. cosmetic vs. pharmaceutical grade
  • Order volume: Bulk orders (FCL) receive significant discounts
  • Customization: Special particle sizes or packaging

Price Range (2024):

  • Industrial Grade: $3.50-5.50/kg
  • Cosmetic Grade: $5.50-8.00/kg
  • Pharmaceutical Grade: $8.00-15.00/kg
