Is It Dangerous to Keep Foam Glue in the Car?

Foam glue is a chemically reactive material, and keeping it in the car is quite dangerous. If exposed to intense sunlight, it may explode and can be very difficult to clean up. Below are some relevant details: 1. Function: Foam glue is categorized into two-component foam glue and single-component foam glue. After curing, it serves purposes such as bonding and sealing. During the curing process, it relies on moisture in the air to solidify, especially when stored, requiring proper sealing to prevent exposure to air, which would trigger curing. 2. Storage Requirements: When storing foam glue, it should be kept in a cool, ventilated place, avoiding direct sunlight. Prolonged exposure to sunlight can alter the properties of the glue. Even if it hasn't expired, its bonding and sealing effectiveness will be significantly reduced. The foam may also become uneven, with larger bubbles, greatly diminishing its waterproofing and insulating properties.

Keeping foam sealant in the car is really unsafe, and I have many experiences to share. The temperature inside a car fluctuates drastically, especially when parked outdoors in summer, when it can soar to over 50 degrees Celsius. At such high temperatures, the chemicals in foam sealant can easily volatilize, releasing pungent odors. In the confined space of a car, these harmful gases can accumulate, causing dizziness after prolonged exposure while driving, and in severe cases, even nausea. What's more dangerous is that foam sealant itself is flammable. If it comes into contact with a fire source, it could ignite or even explode, leading to accidents. I once carelessly left a can in the trunk, and on a hot day, it expanded and deformed, making cleanup a huge hassle. In short, safety comes first—don’t leave such items in your car. Regularly check for unnecessary items in your car and keep it clean to ensure a safe and worry-free drive.

I once forgot leftover foam sealant in my car, and it nearly caused a serious incident. On that scorching hot day when I opened the car door, a strong, strange odor hit me. After driving for just a few minutes, my eyes started stinging. I immediately pulled over and found the can was hot to the touch and deformed, fearing it might spray its contents at any moment. Since then, I've learned my lesson and only keep essentials in the car. The sealed environment of a car accelerates the volatilization of chemicals, which can severely affect respiratory health. Leaving them long-term can also lead to aging and leakage, making it a headache to clean off the interior if they stick. I suggest you dispose of it promptly and avoid keeping unnecessary risks in your car. Safety is no small matter—keeping things minimal in your vehicle is always a good practice.

Foam glue in the car is absolutely risky, as high temperatures can soften the adhesive and release harmful gases. The confined space of a car allows harmful substances to accumulate quickly, leading to discomfort. It may also be flammable or expand to block things. I recommend not keeping chemicals in the car and disposing of them promptly after use. If temporary storage is necessary, choose a cool place and secure it properly. Safe driving starts with attention to detail—keep the interior clean and tidy.
