In the construction industry, silicone waterproofing is an important process that ensures all materials are sealed against the elements. This is especially important in outdoor projects and applications where water and moisture are prevalent. Silicones have a variety of uses, from sealing the inside of a boat to coating surfaces in kitchens and bathrooms. This type of sealant can help protect your project from water damage by creating a barrier that blocks moisture and prevents vapor transmission.
There are a few different types of silicones that can be used for water repellent purposes, and each has its own set of benefits. Silanes, siloxanes and silicone rubber
are all silicon-based substances that offer a similar level of protection. These materials can penetrate the surface of inorganic mineral substrates like brick and stone to create a protective layer. This layer is bonded to the surface and is highly durable. Silicones also offer a high level of breathability, meaning they can be applied to a wide variety of materials without significantly altering their appearance or performance.
Another advantage of silicones is that they are very flexible and have a high tensile strength. This makes them ideal for use in areas that are subject to vibration and movement. Silicones also have a low toxicity and are resistant to a range of chemicals. These properties make them ideal for long-term waterproofing applications.
The chemistry of silicones is based on silicon-oxygen bonds. These bonds form an ordered structure that has a very similar design to the crystals found in inorganic mineral materials. As a result, silicones have a natural affinity for these materials and can bind to their surface. Once the silicone resins bind to the surface of a mineral material, they form a protective film that is tightly bound and will not crack or peel. This is a key benefit of silicones, as it can prevent water penetration from damaging masonry materials.
Another way that silicones can prevent damage to masonry is by reducing water vapor absorption. This helps to reduce vapor condensation, which can lead to frost and other forms of damage to building structures. Silicones are also not affected by ultraviolet light, which means they can be used on a wide variety of surfaces and are not susceptible to fading over time.
