The type of sealant you use for a particular commercial, residential, or industrial application makes a big difference in terms of the longevity and overall strength.
Over the years, polyurethane sealants have earned the designation of becoming the industry standard material to use across a wide range of applications. There’s a good reason for this. Advancements in polyurethane sealant development have made it one of the strongest and most resilient adhesive and binding agents in the building material industry.
Keep reading to learn about all of the different polyurethane sealant application methods, uses, and characteristics.
Sealants are used for a variety of applications in the building, construction, and remodelling industries. Most notably, sealants such as polyurethane, silicone, acrylic, and polymer are used as grouting and insulating materials that fill gaps and waterproof structures to prevent damages such as cracks and leaks.
As a form of insulation, sealants also prevent air flow through building joints (e.g., windows and door frames) to regulate temperatures inside structures. Typically, sealants also have a certain amount of flexibility to allow for some structural movement and prevent damages.
In addition to serving a practical purpose, gap sealants also add to the aesthetic appeal of a structure by hiding minor imperfections that occur during the construction process. Sealant is an inexpensive and easy to apply solution that can boost the functionality and aesthetic of any structure while adding long-term value and stability.
This is an arbitrary term that refers to essentially any combination of sealants that have different chemical compounds. MS polymers are the most commonly used hybrid polymer sealants currently on the market.
Before the invention of silicone sealants, acrylic was the sealing material of choice for many building industry experts. Acrylic is more affordable and durable than silicone in many regards and can be used in a wide range of applications.
Silicone is a synthetic material that’s suited for both indoor and outdoor use. It’s highly resistant to the UV rays of the sun and can withstand hours of exposure to direct sunlight without deteriorating.
Polyurethane sealant is the product of the reaction of two organic compounds, glycol and an isocyanate.
There are different configurations of polyurethane sealants that are currently available on the market. Each one is appropriate for various uses and applications, so always be sure to read the label carefully.
Common characteristics of polyurethane sealant (depending on the specific use and application) include:
There are a number of polyurethane sealant application methods, including:
Since polyurethane sealant is typically sold in 10-ounce tubes, the most common application technique is to use a caulking gun to render absolute precision when sealing tight corners and joints.
Depending on their chemical compound configurations, polyurethane sealants can be used for a variety of construction projects, installations, repairs, and remodelling projects.
Low modulus polyurethane with a shore hardness that goes up to 45 can be used as a connecting agent between two pre-assembled building materials, while polyurethane roof sealants can be used to seal the joints in rainwater collection pipes. Polyurethane construction sealants can also be used to insulate joints between concrete blocks and seal aluminium pipe joints to prevent leaks and cracks.
Polyurethane sealants that have a hardening capacity of 45 and over typically have high surface adhesion capabilities, but minimal flexibility. This type of polyurethane sealant is most suitable for the automotive and HVAC industries. It can be used for auto glass repair as well as sealing metal structures like storage containers, trucks, and car parts.
But it’s also strong enough to be used in the manufacturing and installation of air conditioning systems. Polyurethane sealants not only provide a strong bind and seal metal sheet joints in place, but they also reduce the amount of vibrations while AC units are operating. These are the types of polyurethane products that are typically used for these applications:
