Exterior Insulation and Finish System (EIFS) Additives
Exterior Insulation and Finish System Function and Features
Through adding versatile chemical additives, the EIFS finish system provides better workability, powerful bonding strength, enhanced insulation effect, and prolonged service life. LANDU, a large specialty chemicals manufacturer with rich experience, supplies high-quality EIFS additives, such as cellulose and redispersible polymer products, dedicated to delivering exceptional chemical modifiers for your EIFS formulas.
What are Additives in the EIFS Formula？
Exterior Insulation and Finish System is composed of a bonding layer, insulation layer, plastering layer, decorative layer, and accessories, specifically including adhesive mortars, insulation boards, base coats, anti-cracking mesh fabric, mechanical fasteners, decorative finish coats, and chemical additives. Common additives are water retainers, binders, water reducers, anti-freezing agents, and more. As a mature specialty chemical manufacturer, LANDU dedicates itself to providing the optimal additive solution for the EIFS formula.

LANDERCOLL Cellulose Ethers for EIFS
Specializing in cellulose ether manufacturing, LANDERCOLL provides Hydroxypropyl Methyl Cellulose (HPMC) and Hydroxyethyl Methyl Cellulose (HEMC) used as a binder in external wall insulation mortar. They can not only effectively increase the strength of the mortar but also significantly improve its anti-sagging performance and extend the working time.

Core Additives in the EIFS Finish System
LANDU LANDERCOLL Hydroxypropyl Methyl Cellulose(HPMC) is a water-soluble, non-ionic cellulose ether sourced from refined cotton. Hydroxypropyl Methyl Cellulose has excellent thickening, water retention, film-forming, and adhesive properties, which can effectively improve EIFS construction performance, enhance the permeability of the slurry, and increase the anti-slip properties. It helps prevent premature drying and achieve a more uniform and durable finish.
- Improved Adhesive Strength
- Puikus tirštėjimo efektas
- Pagerintas vandens sulaikymas
- Pagerintas darbo elastingumas
- Increased Anti-slip Property

LANDU LANDERCOLL Hydroxyethyl Methyl Cellulose(HEMC) is a water-soluble cellulose ether modifier widely used in construction materials. Its moisture retention properties maintain optimal hydration levels in EIFS finish systems, enhancing workability while providing structural resilience against substrate movements (preventing crack formation). The thermal stability (75-100℃) of HEMC makes it particularly effective in high-temperature construction environments.
- Better Moisture Retention
- Pagerintas darbo elastingumas
- Sumažintas susitraukimas ir įtrūkimai
- Good Thermostability

As a key additive in EIFS, LANDU ACCURATE RDP powder can significantly enhance the bonding strength between insulation materials and the base wall, and effectively prevent the insulation layer from falling off. It also forms a protective film with waterproof performance inside the insulation material, reducing the water absorption rate of the EIFS finish system and ensuring stable insulation performance even in a humid environment.
- Increased Flexibility
- Water Resistance
- Film-forming Capacity
- Improved Durability

LANDU NOVASTAR Hydroxypropyl Starch (HPS) is a finely powdered, white-modified starch derivative, which is the best-performing variety among various starch ethers. Similar to cellulose ethers, HPS polymer has excellent water solubility, PH stability, and water retention, which can reduce the water consumption of the mortar and improve density and strength. It also improves the workability of the mortar, meaning the thermal insulation mortar is easier to mix evenly during the mixing and construction process, improving the thermal insulation effect.
- Thickening Effect
- Improves Workability and Smoothness of the Mix
- Reduces Segregation and Improves Consistency
- Enhances Water Retention
- Enhanced Adhesion & Cohesion of EIFS
