Clean joints between windows and masonry

131 Multiflex is an odourless silicone sealant for assembling windows and doors. Thanks to its compatibility with a wide range of materials, it is ideal for sealing tempered glass, laminated safety glass and insulating glass in wood, metal and plastic frames, so it can even be used to joint safety glazing designed to prevent falls. 131 Multiflex is also suitable for outdoor use, as it does not suffer any mechanical damage from heavy UV radiation, temperature swings or moisture. The silicone does not damage mirror coatings and can also be used on ceramic finishes. Thanks to its ultra-elasticity, stronger mechanical stress and strain pose no problem. Whether in interior or exterior applications, the silicone maintains a strong hold – even without primer.

Applications

Main applications

Illustration Glasfassade
Sealing and bonding safety glass to prevent falls
When working on safety glazing designed to prevent falls, the professional-grade materials must be compatible with laminated glass.
Illustration einer Fuge in Grün
Sealing expansion joints
An elastic sealant balances out tension between different structural elements.
Sealing windows and doors on the outside
Long-lasting perimeter joints in outdoor areas require resilient and elastic sealants.
Window seals
Weather-proof, easy-to-shape sealants provide attractive and functional joints for the long term.
Installing mirrors
Low-odour and fast-cure materials are suitable for sealing and bonding special types of glass and mirrors.
Sealing display glass
Fast-cure and moisture-tolerant materials are used to bond glass.

Other applications

Sealing cold room panels
When carrying out sealing work in cold storage facilities, the professional-grade materials have to meet some special requirements.
