Typical application methods
Flexible processing for your production
Injection application
The adhesive is injected through a dedicated borehole after the aluminium profiles have been joined. This method introduces the adhesive directly into the corner area of profile systems designed for injection bonding.
Benefits
- Targeted application through injection openings
- Adhesive application after profile assembly
- Access to enclosed corner bonding areas
Classic method
The corner angle adhesive is applied directly into the accessible profile chambers before assembly. Application from the cartridge or with a spatula allows the adhesive to be placed on the bonding surfaces before the profiles are joined.
Benefits
- Direct access to the bonding surfaces
- Visible adhesive placement before assembly
- Application by cartridge or spatula
