To ensure the strength and sealing of the corners of doors and windows, the method for system doors and windows is to use specialized sealant designed specifically for doors and windows, abbreviated as corner glue, to bond the corner code with the corner glue. Hollow wall profiles are used to enhance the structure and sealing effect.

The adhesive corner code is L-shaped and includes two support arms. A continuous guide groove is set along a 45 ° diagonal line at the connection between the two arms. From the positioning groove to the top corner, the outer surface of each support arm is a conical surface, which forms a joint surface. The formed taper creates a groove between the joint surface and the horizontal or vertical reference surface. Two support arms are inserted into the cavities of the horizontal and vertical frames, respectively. At this point, a gap is formed between the joint surface of each arm and the cavity wall of the frame material. Then, glue is injected into the top corner of the guide groove, and the filled glue will flow. In the gap, stick the seams of the horizontal and vertical frames and the cavity wall to the adhesive surfaces of the guide groove and the adhesive corner code, respectively, to complete the corner assembly.

Door and window glue corner code corner glue is a product specially designed to enhance the strength of door and window corners and improve sealing performance. Its performance characteristics should mainly include the following points:

1. After curing, it has high hardness, high strength, good toughness, low elasticity, and excellent waterproof performance. It can form a tough connection between the corner bracket and the cavity wall of the profile, thereby repairing and reducing various deformations and cracking situations, effectively solving the problem of water leakage in door and window corners.

2. High adhesive strength after curing. During the curing process, it will slightly foam and expand, forming an elastic pad at the connection between metals, thereby reducing the transmission of various forces and playing a role in shock absorption and buffering.

3. Strong weather resistance, able to withstand temperature changes from -40 ° C to 80 ° C.
