What Causes the Hook-and-Loop Fasteners on Trunk Mats to Lose Adhesion?
2 Answers
The reason for the loss of adhesion is actually a characteristic of the hot-melt adhesive itself, which is highly sensitive to temperature. When the temperature reaches a certain level, the hot-melt adhesive begins to soften, and below a certain temperature, it becomes brittle. Below are the specific functions of hook-and-loop fasteners: Anti-slip function: During every trip, items can be safely placed in the car trunk. The anti-slip surface of the trunk mat, carefully designed, ensures that items do not scatter due to bumps, providing thorough protection. Waterproof function: The trunk mat is made of waterproof PE material, which is UV-resistant, oil-resistant, and highly durable, preventing sand, mud, water, snow, and oil stains from contaminating the trunk. Anti-contamination function: When transporting plants, goods, or placing wet items and rain gear, the high-edge design effectively prevents spills from contaminating the car. Protective function: Made of high-density foam material, it provides sound insulation and excellent shock absorption. It meticulously protects every corner of the trunk against various intrusions.
I'm quite fond of tinkering with car accessories and have dealt with the issue of trunk mat Velcro not sticking several times. The most common reason is dust and debris accumulating on the hook-and-loop surface, blocking adhesion - just like cleaning debris from carpets. Secondly, Velcro hooks can wear flat or deform from prolonged sun exposure, losing grip. The solution is surface cleaning: use a toothbrush or compressed air to remove dust; if severely worn, just order new Velcro online - it's inexpensive. Also pay attention to trunk conditions - avoid frequently placing sharp objects that cause friction. After my last cleaning, the mat adhered firmly again, staying put even on long trips. Maintenance is key - regular checks prevent problems.
