Silicones are a large class of synthetic materials, including silicone sealants, adhesives, coatings, and other substances that contribute to the durability and enhanced performance of buildings.
The field of building and construction represents the primary sector that extensively utilizes silicones worldwide. In construction, silicone products fulfill various functions such as safeguarding, reinforcing, preserving, and adding aesthetic and innovative elements to structures. Moreover, silicones play a crucial role as production aids during the manufacturing process of numerous industry-critical items. Notably, silicone sealants find widespread application in bathrooms, kitchens, windows, striking glass facades, as well as curved and suspended structures. Their utilization in such areas brings about significant energy efficiency advantages.
Key Benefits of Silicone Chemistry for Building
Silicone chemistry plays a crucial role in extending the durability of exterior paints and coatings, enabling them to withstand the damaging effects of sunlight, salt, pollution, and the passage of time. The unique qualities and benefits offered by silicone chemistry contribute to enhanced paint adhesion, effective dispersion of color pigments, and increased resistance against weather-related damages and stains. When silicone-enhanced paints are applied to the exteriors of buildings and other structures, they exhibit exceptional resilience, remaining intact even during freeze-thaw cycles without experiencing cracks or peeling.
Silicone sealants find extensive use in expansion joints, construction joints, connection joints, and movement joints, ensuring the secure placement of essential structural materials. These sealants also introduce flexibility to building structures, allowing materials to absorb stress and movements caused by wind or earthquakes. By utilizing silicone sealants in buildings, they can be made more energy-efficient by preventing the intrusion of humidity, hot or cold air through joints and cracks.
Silicone adhesives and structural silicone glazing are employed to safeguard and maintain the long-term quality and appearance of building facades, enabling commercial and industrial structures to endure continuous exposure to the elements. For instance, silicone is an integral component of the glazing used on vast expanses of glass, which are characteristic features of modern architectural designs. These facades heavily rely on silicone sealants and glazing to insulate and protect the glass panels from the damaging effects of UV radiation.
Silicone products offer invaluable assistance in the restoration of historical buildings, monuments, and landmarks, including iconic structures like the statues on Easter Island and Tower Bridge in London. By leveraging silicone chemistry, renovation experts can effectively restore these structures while preserving their original appearance and integrity. Silicone sealants and adhesives, for instance, reinforce the inherent strength and resistance to weathering of aging joints and structures. Moreover, silicone materials possess the ability to enhance water repellency and allow for breathability, particularly beneficial for materials such as porous limestone and sandstone that were more commonly used in the past. When silicone coatings are applied, they distribute uniformly, ensuring that they do not mar or streak the surface of older structures.
Types of Silicone Sealants Used for Building And Construction.
Acryfill Silicone Sealants
This particular silicone sealant is created using acrylic emulsions, which involve blending acrylic with silicone.
Acryfill Silicone Sealant is specifically designed for areas that require greater flexibility and will be painted over.
The key reason for selecting Acryfil Silicone Sealant for these specific construction tasks is its superior flexibility compared to other silicone sealants commonly used in construction. Additionally, it can be easily painted over.
Its primary application is for final touches following the main construction phase. It is used to fill gaps between doors, windows, and tiles.
Neutral Silicone Sealants
Neutral Silicone Sealants release alcohol during the curing process and while forming skin. This characteristic makes them odorless compared to other types of silicone sealants.
Neutral Silicone Sealants exhibit strong adhesion properties, making them suitable for bonding materials such as granite, ceramic, plastic, glass, and aluminum.
These materials are commonly used in galleries, museums, and washrooms, making Neutral Silicone Sealants popular for plumbing, sanitary, and decorative purposes.
Due to their waterproof nature, Neutral Silicone Sealants are often used for plumbing and sanitary applications, as they can effectively seal around water surfaces.
Additionally, these sealants do not yellow or crack over time, further enhancing their durability. Therefore, if you need to fix a basin, install sanitaryware, or prevent water leakage, it is recommended to use Neutral Sanitary Silicone Sealant.
General-Purpose Silicone Sealants
General-purpose silicone sealants are commonly employed for household repairs and during house renovations.
They are primarily suitable for smooth and non-porous materials. General-purpose silicone sealants exhibit rapid curing, making them ideal for the construction of glass curtain walls.
Additionally, they are utilized in the fabrication of both small and large-scale aquariums. Furthermore, these sealants are compatible with wood and plastic.
Consequently, they can be employed for various applications such as laying out kitchen plans, bonding cabinets, table tops, and more. During renovation and restructuring projects, they are useful for glazing windows and filling cracks.
General-purpose silicone sealants are user-friendly and can be utilized by amateurs for basic household repairs or for do-it-yourself projects involving cabinets, shelves, etc.
In most instances, it is advisable to use general silicone sealants for indoor building, fixing, and fittings.
Hybrid Silicone Sealant
Hybrid silicone sealants, as the name suggests, are renowned as some of the most robust sealants employed in construction applications.
While neutral, general, and acryfill silicone sealants also possess strength and durability for construction purposes, they are not commonly favored for large-scale projects.
The rationale behind selecting hybrid silicone sealants for extensive construction endeavors lies in their exceptional adhesion properties.
Hybrid silicone sealants are formulated using a combination of silicone and polyurethane technologies. The incorporation of polyurethane technology enhances the sealant’s strength and enables it to form an unyielding bond with surfaces.
These sealants play a vital role in engineering resilient infrastructures, encompassing not only buildings, homes, and bridges but also engines, manufacturing units, and machinery.
Engineers, builders, and developers frequently rely on hybrid silicone sealants for their construction projects, recognizing their superior performance and reliability.
Weatherproof Silicone Sealant
As previously stated, the primary function of silicone sealant is to fill gaps in joints.
During the construction of buildings or glass structures, numerous small spaces often remain at intersections and entryways.
These gaps are effectively sealed using weatherproof silicone sealant, which exhibits non-reactivity towards rain, heat, wind, and UV rays.
It remains resilient in the face of environmental changes, thus providing protection against potential damage to your structure.
Weatherproof silicone sealant finds application in the final stages of large-scale construction projects, as well as in basic terrace installations such as metal roofing and solar panels.
