High-performance Window and Door Corner adhesives
Sika corner bonding solutions offer high performance adhesives for windows and doors. Thanks to the ideally balanced viscosity the technology ensures a clean and easy corner and edge bonding process with optimal filling properties. Maximum efficiency is an additional key benefit which all Sika solutions for corner bonding fulfill. The Sika systems are suitable for a highly automated process as well as for manual application.
SikaForce®-479 L45 - Corner Adhesive for Windows and Doors
SikaForce®-479 L45 is suitable for corner bonding of powder coated and anodized aluminum frames used in windows and doors. SikaForce®-479 L45 is a two-component polyurethane adhesive that cures by reaction when applied and mixed from the side-by-side cartridge using a hand or pneumatic dispenser.
The static mixer is used for homogeneous mixing. At the same time, the tip of the static mixer is thin enough to fit into the injection holes for pre-assembled aluminum profiles.
SikaForce®-479 L45 has an optimum viscosity for most corner bonding applications. Sufficiently pasty for application into the open corner, where the adhesive must not flow. Sufficiently fluid for injection into channels so that the adhesive can be injected well through the channels into the corner.
The many benefits related to the SikaForce®-479 L45
- Ideal viscosity balance for optimal filling
- Tough-elastic behavior - high Shore D hardness combined with high elongation for long service life
- Side-by-side packaging fits in commonly used dispenser
- Static mixer tips fits in injection hole for best filling with no waste
SikaMelt®-677 – the ultimate time saver for Frame Corner Bonding
Reactive hot melt adhesives offer the advantage of high green strength through physical cooling and high strength built up through the subsequent reaction with moisture.
With the help of green strength, the manufacturing process can be accelerated significantly. This property is also an important feature in the production of doors and windows with corner bonding to speed up the production process by up to 4 hours per window or door.
The viscosity of SikaMelt® can be adjusted by the application temperature for optimal and customized corner bonding applications. Sufficiently pasty for application in the open corner, where the adhesive must not flow. Sufficiently fluid for injection into channels so that the adhesive can be injected well through the channels into the corner.
The many benefits related to the reactive
- Highgreen strength enables immediate further processing, no buffering and no waiting time required
- High tensile strength equivalent to 2-component products
- 1-component adhesive with minimal waste, no mixing required
- Excellent thermal resistance
