Silicone Sealant Used in Construction

You may be familiar with silicone sealant if you work in industry or DIY repairs.  Nonetheless, if you are not familiar with the product, you are in the right place. Silicone sealant is a liquid adhesive that looks and feels like a gel. This sealant doesn’t have the same chemical composition as other polymer-based adhesives. It’s designed to stay stable and flexible in both heat and cold. 

Besides that, it’s highly resistant to water, weathering, and other chemicals. For this reason, it’s ideal for many applications. For example, caulking cracks, repairing sinks, level surfaces, bind surfaces like metal, plastic, or glass,  and acting as a bonding agent for car gasket or car engines. Other uses include electrical insulation, electronics coatings, seal cables, sensors, cooking utensils, windows, aquariums, textiles, and paper.

Sealant properties

Some of the main characteristics include:

  • Low chemical reactivity
  • Low thermal conductivity
  • Resist ozone, oxygen, and Ultraviolet. This property makes it useful in the construction industry for fire protection, coatings, and glazing. Also, in the automotive industry for external trim and gaskets.
  • Resist water and build watertight seals
  • High thermal stability from a temperature ranging from -100 to 250 degrees Celsius
  • Prevent microbiological growth
  • Low toxicity
  • Has electrical insulation characteristics. This makes it ideal for various electrical applications; for example, it can be designed to act as an insulator or conductor.
  • High gas permeability is hence significant for medical applications.

\Types of construction Sealants 

If you have never used sealants, you may feel overwhelmed at first when you don’t know the types. These products come with similar basic adhesive characteristics, but they have different functions. 

  • Silicone: they have strong thermal resistance, adhesion, dynamic movement and can be used for structural purposes like bonding, sealing air, and weatherproofing.
  • Water-based latex:  they are easy to apply and can adhere to most substrates. Furthermore, they are suitable for small gaps and voids.
  • Acrylic: they can resist UV hence great for outdoor applications. They are hard to apply, move and shrink.
  • Butyl: they have a stringier consistency. This makes them hard to apply. Additionally, they have poor resistance to weathering and accommodating movements.
  • Polysulfide: they are flexible at shrinkage, low or high temperatures. 
  • Polyurethane: they are highly resistant to forces, weathering and have great adhesion.
  • Polyisobutylenes: they are durable, have low permeability, and can resist chemical attacks.
