Landercoll TM is a trademark for LANDU’s cellulose ether products and derivatives that offers both standard and customized/tailored grade products for your specific industrial application.
Landercoll TM with more than 12 years of production experience enable us to offer an optimized portfolio of cellulose ethers to the construction industry that products are based on cellulose, a natural polymer derived from refine cotton fibers. We offer the following main cellulose ether types,
Hydroxypropyl Methyl Cellulose (HPMC)
Methyl Hydroxyethyl Methyl Cellulose (HEMC/MHEC)
Hydroxyethyl Cellulose (HEC)
All three groups are obtained through a chemical substitution process known as etherification.
Landercoll TM cellulose ethers are unique in the industry and have been developed to impart a range of properties in dry mix mortars. Depending on the end-user requirements,Landercoll TM products provide:
• Increased water retention
• Improved consistency to make thin layer products workable
• Controlled rheology to provide sag resistance
• Reduced segregation of different formulation ingredients
• Improved adhesion on porous substrates
• Optimized air pore stability for improved workability
• Improved adhesion to polystyrene boards
In addition to the conventional uses of Landercoll TM cellulose ethers in dry mix mortar formulations, our products are also recommended as rheology modifiers for ready-to-use dispersion based pasty systems.
AccurateTM is a trademark for LANDU’s VAE re-dispersible polymer powder product,and AccurateTM RDP products form a complementary technology to Landercoll TM cellulose ethers portfolio.
AccurateTM VAE Re-dispersible Polymer Powders have a decisive influence on cement, lime or gypsum-based finished dry-mix mortar products, as well as on cement free and mineral-binder free system. Our free-flowing re-dispersible polymer powders are obtained through spray-drying of optimized latex dispersions.
Our expertise in the development and production of special latex dispersions allows AccurateTM to supply an unprecedented range of products specifically developed to bring defined improvements to a wide range of mortars:
- Excellent mortar workability
- Increased adhesion to porous and nonporous substrates
- Reduced rigidity and improved flexibility
- Increased abrasion resistance
- Reduced water adsorption
- Ensured long term durability
