Installation Tips for Adhesive Hook-and-Loop Fasteners: Whether installing original adhesive hook-and-loop fasteners or our high-adhesion, heat-resistant adhesive versions, first ensure the plastic frame surface is clean, free of dust and grease. Mark the desired position, then peel off the release liner starting from the center of the forehead section. Slowly align and peel the liner away from both sides to complete installation. Here's the most critical part: After installation, press firmly but do NOT immediately attach the foam mask. The adhesive hook structure is still unstable at this stage, and even slight adjustments to the mask could compromise adhesion. The correct procedure is to wait at least 24 hours to allow the adhesive to reach full bonding strength before installing the foam mask!
