Sika - SikaHyflex-600 curtain wall and metal façade sealant

One-component sealant used for curtain walls and facades with metal cladding. It binds when exposed to moisture in the air.

Features

• high quality
• resistance to weather conditions
• flexibility
• low modulus of elasticity
• 25% displacement transfer capacity (ASTM C 719)
• very good machinability
• neutral binding

Application

The product is often applied in places where the appearance of the sealant is important due to the transparent color. It is mainly used as a sealant for shop front walls, glass segment walls and similar applications.
