Usage Guide
1.Shielding Protection:

Use masking tape to cover both sides of the joint to prevent adhesive fromcontaminating non-bonding areas(remove after curing).

2.Adhesive Tube Opening and Loading:

① Cut the nozzle of the adhesive tube at a 45° angle, adjusting the apertureaccording to the joint width (typically 1/2 of the joint width).

② Load into the caulking gun and expel the unevenly mixed adhesive at thefront end (approximately 5-10 cm).
3.Gluing Techniques:

① Continuous Gluing: Move the caulking gun at a uniform speed toensure the adhesive strip is full without breakpoints.

② Filling Depth: The joint filling should be ≥75% (full filling required forstructural bonding),with an adhesive thickness of 6-12 mm recom-mended.

③ Cross-Section Shape: Adopt a "triangular" or "concave" cross-section(avoid flat surfaces) to facilitate stress dispersion.

4.Trimming and Compaction:
① Use a scraper dipped in soapy water to level the adhesive surface,remove air bubbles, and compact the adhesive (improving density).

②Remove the masking tape immediately after trimming (to avoidadhesion after the adhesive is semi-cured).
