Why Silicone For Underwater Use is Necessary?

As an avid scuba diver, I have had my fair share of experiences with various underwater equipment. One thing that I have learned is the importance of using silicone for any gear that will be submerged in water. Whether it’s a mask, snorkel, or fins, silicone has become the go-to material for underwater use, and for good reason.

First and foremost, silicone is extremely durable and can withstand the harsh conditions of the ocean. It is resistant to saltwater corrosion, which can quickly deteriorate other materials like rubber or plastic. This means that my equipment will last longer and perform better, making my diving experience more enjoyable.

Furthermore, silicone is also very flexible and comfortable to use. It can easily mold to different shapes without losing its strength or elasticity. This is especially important for items like dive masks, which need to create a tight seal against your face to prevent water from entering. The flexibility of silicone ensures a comfortable and secure fit every time.

Lastly, silicone is non-toxic and hypoallergenic, making it safe for both marine life and human use. As divers, we have a responsibility to protect the underwater environment and using silicone helps us do just that. It does not

My Buying Guide on ‘Silicone For Underwater Use’

As an avid scuba diver and underwater photographer, I have learned the importance of using high-quality silicone for underwater equipment. Silicone is a versatile material that is commonly used for sealing and waterproofing various items, making it an essential component for any water-related activity. In this buying guide, I will share my personal experience and tips on choosing the best silicone for underwater use.

1. Understand the different types of silicone

Before purchasing silicone for underwater use, it is crucial to understand the different types available in the market. The most common types of silicone used for underwater equipment are RTV (room temperature vulcanizing) and LRTV (low-temperature vulcanizing) silicones. RTV silicone is suitable for general use while LRTV silicone is specifically designed for extreme temperatures, such as those found in deep water diving.

2. Look for a high-quality brand

When it comes to silicone for underwater use, quality matters. Cheaper brands may not be suitable for prolonged exposure to water and can degrade quickly, compromising the integrity of your equipment. It is always best to invest in a reputable brand that has been tested and proven to perform well in underwater conditions.

3. Check the curing time

Curing time refers to how long it takes for the silicone to dry and form a strong bond. When using silicone for underwater equipment, it is important to choose a product with a relatively fast curing time so that you can get back into the water as soon as possible. Typically, RTV silicones have a shorter curing time compared to LRTV silicones.

4. Consider flexibility and durability

Underwater activities require equipment that can withstand pressure, temperature changes, and constant movement. Therefore, it is essential to choose a silicone that is flexible and durable. Look for products that have high elongation and tear strength to ensure they can withstand the rigors of underwater use.

5. Read reviews and seek recommendations

Before making a purchase, it is always helpful to read reviews from other users who have experience with the product. This will give you an idea of its performance and durability in real-life situations. You can also seek recommendations from fellow divers or professionals in the industry for their preferred brands and types of silicone for underwater use.

6. Consider the specific needs of your equipment

Different types of equipment may require different types of silicone. For example, if you are sealing a camera housing, you may need a more flexible silicone compared to sealing a diving mask strap. Consider the specific needs of your equipment and choose a silicone that will provide the best protection and waterproofing.

In conclusion, choosing the right silicone for underwater use is crucial for maintaining the integrity and functionality of your equipment. By understanding the different types available, checking for quality and durability, and considering specific needs, you can ensure that your gear remains protected in all water conditions. Remember to always follow manufacturer instructions for proper application and curing time. Happy diving!
