The Benefits of Using a Polyurethane Based Sealant

Distributor of high-performance, polyurethane adhesive sealants. Offers a wide range of products such as glass, metal, concrete, wood, acrylic and vinyl adhesive sealants. Provides a variety of applications including marine, automotive and industrial.

Unlike silicone sealants, polyurethane based sealants are very durable and long lasting. They are also extremely versatile and come in a large array of formulations.


The strength of a polyurethane sealant depends on how it is formulated and how much pressure it is put under. It is also important to check whether the product is rated for outdoor use. This way you can be sure that it will not deteriorate or become brittle over time and will be able to stand up to the elements.

Polyurethane sealants are noted for their flexibility. This makes them very useful for sealing joints that are subject to polyurethane based sealant movement such as expansion and contraction. They are also highly resistant to cracking that may occur due to the movement of joint materials.

These sealants are available as either one or two component compounds. The basic residential type usually only has one component so that it is easy to use. They are also available in a variety of colours.

Before using a polyurethane sealant it is important to ensure that the surface that will be sealed is clean and free of dust, crumbly particles, rust from metals and any other contaminants that may prevent the adhesive from bonding properly. The surface should be sanded and thoroughly cleaned with a solvent to remove any dirt or debris that might be present.


The durability of a sealant or adhesive will affect the length of time it lasts, and it also impacts the warranty duration that manufacturers offer. Typically, polyurethane sealants and adhesives have a longer lifespan than silicone.

They are able to withstand the elements of nature. This is why they are used in the transportation industry to seal and bond the parts of vehicles such as cars, trucks, trailers, trains, and boats.

This type of adhesive is also very useful in construction projects to seal joints and gaps. It is a great caulking agent that can be used on metals, concrete, wood, glass, galvanized and painted sheet iron and other common construction materials.

It is very durable and can withstand high pressure, abrasion, and moisture. It is also very easy to install and maintain. It is a great choice for areas that require high mechanical strength, and it has a better resistance to water than silicone sealants. It can be painted to match the surface of the area where it is installed. It is also flexible and can accommodate movement of construction materials.


Using the right adhesive in sealing and bonding is essential to a long-lasting project. There are various types of adhesives available and each has its own benefits. However, polyurethane adhesives are one of the most popular choices for a variety of projects. These adhesives provide good stress-restraint, abrasion resistance and adhesion to different surfaces. They can be used in concrete, metal and wood applications. They also provide a nice, attractive shine to materials like flooring and furniture.

Polyurethane adhesives and sealants are suitable for numerous materials and bond to porous and nonporous surfaces including metals, cement, glass, most plastics, cellulose, paper and leather. They are also ideal for bonding dissimilar materials. They also have excellent water resistance.

They are moisture cure, gun grade and non-sag adhesives that can withstand up to 70% joint movement. This makes them ideal for use in joints that move because of structural movements, weather changes and thermal expansion and contraction. They are commonly used in window and door frames, skylights, drywall, foundations and concrete driveways. This type of sealant is also available in low VOC formulations for indoor and outdoor use.


Sealants fill gaps, preventing air and water penetration while absorbing the natural expansion and contraction of building materials. They are especially important for areas that receive heavy use, such as in building joints or plumbing pipe connections. In construction projects, there are many different types of sealants available to choose from. However, not all are appropriate for every job.

In terms of elasticity, polyurethane adhesives and sealants have superior flexibility. They can easily withstand the expansion and contraction of polyurethane based sealant the building materials without breaking apart or cracking. This makes them suitable for sealing concrete, metal, and asphalt applications.

Additionally, a polyurethane sealant can keep its elasticity and flexibility even in extreme temperature conditions. This is particularly useful for outdoor applications, as weather fluctuations can cause many different types of sealants to break down. Unlike silicone, a polyurethane sealant is organic, making it more resistant to the effects of UV light from sunlight. As a result, it will continue to provide a strong seal for the long-term. It is also paintable, allowing it to be used in applications that require painting work.

Moisture Resistance

Sealants play an important role in the construction of buildings. They are used for sealing, filling gaps, keeping water and air away from joints, absorbing the natural movements of materials in structures and improving aesthetics. However, not all sealants are suitable for all applications. While silicone sealants are widely popular among DIYers, a polyurethane-based sealant is more effective for structural applications.

Unlike silicon, a polyurethane-based caulk has high resistance to moisture. It is also a highly flexible material that can absorb movement without cracking or crumbling. These qualities make it the ideal choice for outdoor structural applications.

Before applying a polyurethane sealant, ensure that the surfaces are clean and dry. Then, follow the manufacturer’s instructions for applying the product. You can use a caulk gun to apply a bead of sealant in the area you’re sealing. Then, smooth it with a damp rag or sealant tool to achieve an even surface. Once the sealant is cured, it’ll be able to resist moisture, chemicals and weathering for years. This is the best option for any outdoor construction project.
