Aluminium window & door adhesives & sealants
Corner angle bonding & sealing solutions
Reliable aluminium frame connections require the right adhesive system and bonding method. COSMO® offers one- and two-component polyurethane adhesives for corner connector bonding, complemented by MS adhesive and sealant solutions for elastic bonding, sealing and corrosion protection.
Discover suitable products for classic and injection bonding methods, as well as complementary solutions for durable aluminium window and door manufacturing.
Two bonding methods for aluminium frame corners
Depending on the profile system and production process, aluminium corner connectors are typically bonded using either the injection method or the classic method.
Injection application
After the aluminium profiles have been mechanically assembled, the adhesive is injected through a dedicated borehole and distributed through the corner connector into the defined bonding areas.
Suitable adhesive systems:
2-component adhesives
- Adhesive application after profile assembly
- Controlled distribution into enclosed bonding areas
- Ideal for profile systems designed for injection bonding
Classic method
The adhesive is applied directly to the accessible profile chambers and bonding surfaces before the aluminium profiles and corner connectors are assembled.
Suitable adhesive systems:
1- or 2-component adhesives
- Direct and visible adhesive application
- Application before profile assembly
- Flexible choice between ready-to-use 1-component and 2-component systems
2-Component PUR Adhesives
For injection and classic corner bonding
Two-component PUR adhesives provide controlled curing independent of ambient moisture and are particularly suitable for structural corner bonding and injection applications.
