UNICRYL B SERIES
MULTIFUNCTIONAL PROTECTION FOR CONSTRUCTION
Versatile waterborne acrylic resins with superior performances in:
MORTAR FLEXIBILIZATION
• FAÇADE PROTECTION
UNICRYL B 45
Unicryl B45 Molecular structure interacts with the hydraulic binder, acting as plastic matrix. The result is the formation of a composite mortar which is elastic and extremely flexible. It is also hydrophobic, weather and freeze-thaw resistant
