External Thermal Insulation Composite Systems Additives

Enhance adhesion, flexibility, impact resistance, and durability with LANDU high-performance cellulose ether (CE) and redispersible polymer powder (RDP) for EIFS / ETICS applications.

What is EIFS / ETICS?

The External Insulation and Finishing System (EIFS / ETICS) is an energy-efficient and versatile wall system widely used in residential, commercial, and high-performance building projects.

LANDU EIFS additives improve the performance of adhesive mortars, base coats, and top coats, enhancing water retention, open time, workability, and crack resistance.
