Landercoll® Carboxymethyl Cellulose (CMC) for Papermaking

High-Performance Additive for Surface Sizing, Coating, and Pulp Enhancement

Landercoll® Carboxymethyl Cellulose (CMC) from LANDU is a high-quality, multi-functional cellulose ether developed specifically for the papermaking industry.

It provides superior film-forming, thickening, binding, и water‑retention properties, offering exceptional performance in surface sizing, pigment coating, and pulp processing applications.

With excellent dispersibility, rheological control, and compatibility with other papermaking chemicals, Landercoll® CMC empowers producers to achieve brighter, smoother, and stronger paper, meeting the most demanding requirements for printing and packaging grades.

✓ Superior film-forming & binding
✓ Excellent water retention
✓ Enhanced brightness & smoothness
✓ Optimized rheological control

⚙️ Main Functions

Main Functions of CMC in Papermaking

01
📋

Surface Sizing – Strength, Smoothness, and Printability

▸ Rheology & Film Formation

Regulates viscosity for uniform coating layer formation.

▸ Pore Sealing & Barrier Improvement

Reduces surface porosity, enhancing oil, ink, and water resistance.

▸ Brightness & Gloss

Contributes to improved optical properties and smooth surface appearance.

▸ Stiffness & Curl Control

Prevents deformation, enhances sheet rigidity, and ensures consistent lay-flat properties.

▸ Surface Strength

Reinforces fiber bonding and abrasion resistance, reducing linting, dusting, and surface picking during printing.

🧪

Pulp Additive – Enhanced Fiber Bonding and Strength

  • • Acts as a wet‑end retention and bonding aid, improving the interaction between cellulose fibers.
  • • Increases dry and wet strength, ensuring better sheet formation and internal cohesion.
  • • Enhances fiber residence time and drainage behavior for higher process stability.
03
🎨

Pigment & Paper Coating – Texture and Optical Balance

  • • Improves dispersion stability of pigments and fillers, reducing aggregation or streaking.
  • • Provides ideal rheology for high‑speed coating operations, optimizing coater performance.
  • • Enhances color strength, opacity, and surface smoothness, producing a uniform, glossy finish.
