With the popularity of short videos and we-media, the demand for highly playable and underwater motion cameras has also increased. The camera is very waterproof during underwater shooting. To ensure the normal use of the camera underwater and for long periods of protection, the choice of waterproof sealant becomes key. This article will introduce the waterproof sealant of PC shell for underwater camera, and provide professional suggestions for five major scenarios.
 
 Underwater camera dedicated PC shell waterproof sealant features
1. High strength waterproof performance: high quality waterproof sealant has excellent waterproof performance, and can be sealed for a long time in the high pressure underwater environment to prevent moisture from infiltrating into the camera.
2. Corrosion resistance: there are many salts and other chemical substances in the underwater environment, and the waterproof sealant should have good corrosion resistance to avoid seal failure caused by chemical reactions.
3. High and low temperature resistance: in the deep sea or polar environment, the temperature changes dramatically, so the waterproof sealant needs to have good high and low temperature resistance to ensure that it can work normally at extreme temperatures.
4. Flexibility: The waterproof sealant needs to have good flexibility, which can still maintain the sealing effect when the camera is subjected to external pressure or impact.
5. Low volatility: the volatile substances of waterproof sealant will remain in the electronic equipment, and gather, easy to cause equipment corrosion and short circuit, so it is necessary to choose low volatile sealant products.

Use scenario 1: Diving photography
Diving photography is one of the main scenes of the underwater cameras used, whether professional photographers or diving enthusiasts, will use the underwater cameras to capture the beautiful underwater landscape. In this scenario, the choice of waterproof sealant is particularly important.
 Suggested type of use: high strength waterproof sealant, with excellent waterproof performance and corrosion resistance.
 
 Use scenario 2: Marine research
In Marine research, scientists often need to use underwater cameras to photograph and monitor long underwater to record changes in Marine life and the environment. At this point, the durability and stability of the camera are particularly important.
 Suggested type of use: high and low temperature waterproof sealant, which can maintain stable waterproof performance in extreme environment.
 
 Use scenario 3: Outdoor adventure
In outdoor adventure activities, underwater cameras often need to face a variable environment and frequent use, and the durability and ease of use of waterproof sealant is particularly important.
 Recommended use type: flexible waterproof sealant, can adapt to a variety of complex environments.
 
 Use scenario 4: Water sports
In water sports such as surfing, boating, and rafting, underwater cameras are not only waterproof, but also able to withstand external impacts and wear and tear. Therefore, the durability and protective performance of waterproof sealant is particularly critical.
 Recommended use type: high strength protective waterproof sealant, with good impact resistance and wear resistance.
 
 Use scenario 5: Underwater engineering
In underwater engineering fields such as underwater construction and pipeline maintenance, underwater cameras are used to record and monitor progress. At this time, the waterproof sealant should not only be waterproof, but also need to have pressure resistance and corrosion resistance.
 Suggested type of use: professional grade waterproof sealant, suitable for deep water high pressure environment.
 
 Choose the right waterproof sealant
Combined with the above five scenarios, the MS modified siloxane sealant ENIENT EG0510 series can easily GET. Its curing speed is 3~5 times that of ordinary silicone, and its tensile strength is 2~4 times that of ordinary silicone. It can stick to more kinds of materials, including PBT, nylon, PVC, and inert gold-plated materials that are difficult to attach. It has better aging resistance to damp and heat. In the double 85 damp and heat experiment, 3000 hours of aging performance is completely unchanged, which is equivalent to having a life span of more than 60 years in a natural environment of 60% humidity at 25 degrees Celsius. Modified siloxane sealant has a lower volatile amount of siloxane small molecules, which is one of dozens of ordinary silica gel. Therefore, it is more stable and reliable when used in electronics, especially near the contacts.

sum up
The PC shell for underwater cameras plays a crucial role in five use scenarios: underwater photography, ocean research, outdoor exploration, water sports and underwater engineering.
 The choice of high-quality waterproof sealant is not only the protection of the equipment, but also the guarantee of every underwater exploration. It is the secret magic weapon for manufacturers to enhance their reputation and enhance their competitiveness.
