Application Area
ETICS / EIFS are multi-layer façade systems for thermal insulation, mechanical stability, and weather resistance. wheChemical supports these formulations with coordinated material systems for reliable processing and durable façade performance.
Extended open time for long-termReliable water retention and sufficient open timetile positioning
Stable rheology and good stand-up behavior on vertical surfaces
Strong adhesion to insulation boards and mineral substrates
Crack resistance and mechanical stability in base coats
Predictable curing and strength development
Long-term durability under climatic exposure 
ETICS / EIFS systems require secure bonding to insulation boards and mineral substrates throughout installation and service life
Solution: Improve bonding with balanced water control.
Solution: Optimize rheology to achieve good stand-up behavior and stable application on vertical surfaces.
Solution: Optimize rheology for vertical stability.
Base coats must withstand thermal movement, substrate stress, and environmental exposure without losing integrity.
Solution: Increase crack resistance and stability.
Moisture, wind load, and temperature variation place continuous stress on ETICS / EIFS façade systems
Solution: Improve curing and weather durability.Do you have any questions or comments about our products? Reach out to our sales team, always ready to help you.
