Why Choose a Silicone Sealant?

Whether you’re mending a leaky sink, sealing around a window or door frame or working on other projects that will be exposed to moisture, there are plenty of reasons why you might choose a silicone sealant. They offer great durability and are very resistant to water, chemicals and weather.

There are also a variety of different types of silicone sealants for a wide range of uses. Depending on the job, you’ll likely find that the most suitable choice is:


Silicone sealants are durable, long-lasting glues. They can be used for various projects including home repair and maintenance, caulking, and glass and plastic bonding in craft and pet projects such as terrariums and aquariums. They can also be used for industrial and manufacturing purposes.

Silicones are often weather-proof and can withstand different types of harsh environmental conditions. They are chemically unreactive and do not promote mould growth, making them ideal for a range of different applications.

In homes, silicone sealants are typically used to prevent mould from growing in areas that experience moisture. These include bathrooms and kitchens, where high levels of humidity can cause condensation which then leads to the growth of Silicone Sealant mould. Silicones create an airtight seal around these areas to stop unwanted moisture from entering the room and stopping it from spreading. They are also available in a variety of colours so that they can be easily applied to fit the decor in a room. GE silicones can be used on a variety of materials and surfaces including metal, glass, wood, and plastic.


Silicone sealants are very flexible, enabling them to stick and remain in place even after long periods of time. They also do not promote mould growth and can bond effortlessly to a variety of different surfaces and materials. These versatile characteristics have made silicone adhesives and sealants popular for a number of applications, including home repairs and maintenance, construction sealing and adhesion, craft or pet projects (such as terrariums), and manufacturing or production uses.

There are many kinds of silicone adhesives available, and selecting the right one for your needs is important. For example, for applications in wet environments, a multipurpose silicone adhesive that contains anti-mold properties, such as Akfix 100S, is an ideal option.

For industrial purposes, silicone rubber sealants are used to create airtight seals on equipment and machinery. This helps prevent contamination from outside elements that can cause damage or wear to parts. It is also common for manufacturers to use silicone boot sealants on rotary buttons, push buttons and circuit breakers. These rubber sealants are designed to withstand the vibrations and temperature changes that can occur in industrial settings.

Moisture Resistance

Silicone sealants are known for their moisture resistance and this is one of the reasons they’re used for many different applications. This makes them ideal for use in areas of the home that experience a lot of dampness, such as bathrooms. This is because the sealant helps to prevent moisture damage caused by condensation, mould and mildew growth, as well as preventing water leakages from pipes.

If you want to make sure your silicone sealant is durable, check whether it is resistant to weathering, ozone and UV radiation. This will help to ensure it retains its flexibility and strength, even in extreme temperatures.

For a general purpose commercial silicone, you can also look for one that has been formulated with biocides, which are chemicals developed to combat the growth of harmful microorganisms in industrial applications. This is important as it prevents damage from fungus, mold and mildew on surfaces that may be vulnerable to the effects of moisture penetration, including metals, plastics, wood and concrete. The LePage 2 in 1 Kitchen and Bath Express Silicone sealant is a great example of this as it has been specially formulated to be resistant to moisture penetration and fungus, as well as providing excellent durability.

Chemical Resistance

Silicone sealants can be used to prevent damage from the effects of chemicals. They create a strong, durable seal that keeps water and moisture from seeping through the joint or seam. This makes them ideal for sealing electrical connections, or for waterproofing outdoor projects.

These properties also make silicone sealants useful for gluing or sealing many different types of materials, such as glass, rubber, metal and wood. Specialized silicones can be used to seal and bond delicate surfaces, such as aquariums. Anti microbial silicones are available that contain an EPA approved biocide, which is great for applications that will come into contact with food.

Heat resistance is another essential feature of silicone sealants, as it can withstand high temperatures without melting or degrading. This type of silicone is commonly used in automobiles, to seal areas such as valve covers, axle housings and water or oil pump seals. Additionally, fire retardant silicone is available that has been specially designed to resist the effects of smoke and toxic gases. These features also make silicones suitable for use in ovens and ductwork.

Heat Resistance

Silicone sealants are able to withstand extremely high levels of heat. This is due to the stable structure of the silicone molecules and their coiled shape. These properties can help prevent damage caused by a temperature change. Some silicones contain biocides to control the growth of harmful microorganisms like mildew and fungus.

These sealants are also Silicone Sealant resistant to chemicals and other substances that might cause damage. These include ozone, UV radiation and thaw/freeze conditions. This helps to protect the integrity of the sealant and prevent cracking and deformation over time.

Many people use these products on metal items such as sinks and showers in their homes. Using the right type of silicone for these areas can help ensure that it will not corrode the metal or cause other problems.

Heat resistant silicones are often used in automobiles because they can withstand the heat of an engine. These can be found in places like valve covers, axle housings and water pump seals. They can also be applied to areas that are exposed to very high temperatures such as ovens and heating systems.
