Why Advanced Materials Manufacturers Invest in Hybrid and Eco-friendly Polyurethane Sealants?

Highlights

• Introduction
• Applicability of polyurethane sealants
• Key product launches

Polyurethane sealant, a single-component elastomeric sealant, solidifies at room temperature and in humid conditions. The primary reason for its widespread use lies in its excellent elasticity and strong adhesion to various surfaces. In addition, polyurethane sealant exhibits notable resistance to impact, vibration, and motion. Moreover, its mechanical strength is more than that of silicone. The global polyurethane industry is anticipated to manifest the fastest CAGR of 4.6% by 2032.

The construction sector fuels the expansion of the polyurethane sealants sector due to the widespread utilization of these sealants for sealing joints, gaps, and cracks in various construction projects such as buildings, bridges, highways, and other infrastructure developments. Moreover, the rapid pace of urbanization and population growth contributes to a surge in the number of construction activities, which drives the demand for polyurethane sealants. With urban areas expanding, there is an upsurge in need for sealing and bonding materials in both residential and commercial construction projects.

Dynamic potential of the polyurethane sealants

Polyurethane sealant is highly valued for its flexibility and durability, both essential qualities for applications withstanding movement, temperature changes, and stress. Its elasticity enables it to resist dynamic stresses without developing cracks or compromising its sealing abilities. This flexibility proves particularly advantageous in construction joints & structures, automotive uses, and industrial settings where movement and stress are prevalent. Moreover, its durability ensures the sealant remains effective over extended periods, reducing the frequency of replacements required.

Automotive and marine sector

Polyurethane sealants are utilized in the automotive and marine industries for sealing and bonding purposes. Within vehicles, these sealants play vital roles in bonding auto glass, sealing body seams, and assembling windshields to optimize structural integrity while minimizing noise and vibration. Similarly, polyurethane sealants are used to seal windows, deck joints, and boat hulls, offering water-resistant and durable seals capable of enduring the harsh conditions of marine environments. The versatility of polyurethane sealants in adhering to various substrates makes them indispensable for preserving the integrity of automotive and marine structures.

 

Ecofriendly and hybrid polyurethane sealants are trending

Manufacturers are increasingly turning to eco-friendly sealant solutions as sustainability gains momentum in consumer preferences. This shift involves the development of products with low levels of volatile organic compounds, harmful solvents, and isocyanates. Government regulations and the rise in demand for environmentally friendly options are key drivers behind this trend.

Another notable trend in the industry is the adoption of hybrid polyurethane sealants. By combining the advantages of silicone and polyurethane, these sealants offer enhanced adhesion and flexibility. They exhibit excellent resistance to saltwater, extreme temperature, and chemicals by opening new opportunities for their utilization in the marine sector.

Strategic alliances by frontrunners to dominate the industry

The global polyurethane sealants industry has transformed due to the expansion of the automotive sector, strict environmental regulations, and increase in its demand for this sealant in the construction industry. To sustain the evolving sector, top players have adopted novel strategies such as new product launches, acquisitions, collaboration, partnerships, and mergers. For instance, in July 2021, the adhesive solutions division of Arkema, Bostik, embarked on an ambitious development program aimed at enhancing its polyurethane (PU) sealants, with a specific emphasis on sealing and bonding applications in the construction sector. This new lineup of products positioned Bostik strongly in this sector, driven by the rise in the number of construction activities in emerging economies and the consistent demand for superior-quality solutions.

Similarly, DAP launched a one-component broadcast spray foam with a wide spray applicator, Wall and Cavity Foam in November 2023. This innovative product utilizes polyurethane sealant technology, offering an easy-to-use spray-ready solution in a single can with two-component spray foam.

To sum up, polyurethane sealant is greatly appreciated for its flexibility and durability, both crucial attributes for applications withstanding movement, temperature fluctuations, and stress. Its elasticity empowers it to resist dynamic stresses without forming cracks or compromising its sealing capabilities. Moreover, manufacturers have shifted to hybrid and eco-friendly polyurethane sealant production to achieve sustainability goals.
