What kind of glue is used for car phone mounts?
2 Answers
Car phone mounts commonly use silicone adhesive. Here is some relevant information about silicone adhesive: Advantages: 1. Fast curing, achieving a firm bond in 3-6 seconds. 2. No special surface treatment is required for silicone; adhesive can be directly applied. 3. High strength, ensuring no detachment for silicone with hardness below 70 degrees. 4. Complies with EU and US ROHS certification. 4. Excellent properties such as resistance to high and low temperatures, electrical insulation, oxidation stability, weather resistance, flame retardancy, hydrophobicity, corrosion resistance, being non-toxic and odorless, and physiological inertness. Disadvantages: 1. Not suitable for large-area bonding. 2. The bonded area of silicone may harden slightly.
I made a mistake when sticking my phone mount before, using stationery store double-sided tape that softened and fell off in the summer heat, causing my phone to drop dangerously. Later, I switched to 3M's automotive-grade double-sided tape, the VHB foam type. Before applying, you must thoroughly clean the surface with alcohol to ensure it's dust-free and grease-free. This tape withstands high temperatures and doesn't fear the 60°C heat inside the car, absorbing vibrations and staying secure for a year without falling. For uneven surfaces or if you want to move it, use hook-and-loop tape, though its adhesion is weaker. Good tape may be more expensive, but it saves hassle and prevents accidents. Related experience: When removing, use a hairdryer to heat it for easy removal without leaving marks. Strong adhesives like universal glue can be hard to remove and damage the interior.
