What is Polyurethane Coatings ? Why Choose?

Polyurethane coatings are one of the innovative solutions used to protect surfaces and provide a decorative appearance. These coatings stand out for their high chemical resistance and superior protection against environmental conditions. Thanks to their flexibility and durability, they offer long-lasting use. They find wide application in industrial areas as well as sports halls. Polyurethane coatings provide effective protection against harsh environmental conditions in both indoor and outdoor environments. By combining aesthetics and functionality, they offer sustainable solutions.

What is Polyurethane coatings ?

Polyurethane coating is a high-performance coating material that can be applied in liquid form and, once dried, forms a protective film that can be either hard or soft depending on the surface.

This type of coating is particularly known for its resistance to environmental conditions. Polyurethane coatings create a protective layer on various surfaces, providing superior protection against abrasion, chemical effects, UV rays, and moisture.

Polyurethane coatings are formed from the reaction of polyol and isocyanate and are divided into two categories: flexible and rigid polyurethane. Flexible polyurethane coatings are typically used indoors, in insulation and sports flooring, and make surfaces resistant to impacts and wear. Rigid polyurethane coatings, on the other hand, are used in industrial and commercial applications to create durable surfaces that can withstand challenging environmental conditions.

Thanks to their advanced polymer structures, polyurethane coatings show high resistance to cracking and wear, providing long-lasting and reliable surface protection. Additionally, with formulations containing low VOC (volatile organic compounds), they offer environmentally friendly properties. With these features, polyurethane coatings provide an excellent solution in terms of both aesthetics and performance.

Advantages of Polyurethane Coatings

Polyurethane coatings offer a range of superior advantages compared to other types of coatings, helping us understand why polyurethane is preferred in various applications.

  1. Flexibility and Surface Adaptation: The flexible structure of polyurethane coatings reduces the risk of cracking and peeling. Additionally, it provides excellent adhesion to different surface types. Its self-leveling nature helps form a coating layer that covers surface irregularities and imperfections, improving the surface’s appearance and creating a seamless finish.
  2. UV Resistance and Color Stability: Polyurethane coatings formulated with aliphatic structures exhibit high resistance to ultraviolet (UV) rays. This prevents issues like fading, yellowing, or deterioration caused by UV exposure over time.
  3. Waterproofing Property: Polyurethane coatings also act as excellent waterproofing materials, creating an impermeable layer that prevents water from passing through where it is applied.
  4. Chemical and Abrasion Resistance: Polyurethane coatings offer resistance to various chemicals, making them durable in industrial environments and in areas where hygiene is important.
  5. Ease of Application and Maintenance: Polyurethane coatings can be applied using various methods (brush, roller, spray), ensuring perfect surface coverage. Additionally, due to the application techniques used, polyurethane coatings result in fewer air bubbles and surface irregularities.

Types of Polyurethane Coatings and Their Applications

Polyurethane coatings offer a wide range of usage options with various types tailored to different application needs. Each type has its unique advantages and ideal areas of use.

1. Polyurethane Sports Flooring Coatings

Due to their superior properties, polyurethane systems are commonly used in the flooring of sports facilities for performance-demanding athletic tracks, and indoor and outdoor sports such as basketball, volleyball, and handball. These types of flooring vary based on their wear resistance, degree of flexibility, and topcoat requirements.

2. Polyurethane Industrial Floor Coatings

Polyurethane coatings are also encountered on industrial floors that require high abrasion and hardness and where vehicle and pedestrian traffic is high. Such floors require the coating material to have bridging properties in the joint gaps where concrete mobility is high. At the same time, it creates a monolithic image and creates a water impermeable layer.

3. Polyurethane Hydroisalation Coating

Polyurethane coatings are indispensable for waterproofing due to their excellent hydrophobic properties and adaptability to outdoor conditions. Polyurethane coatings are preferred as the biggest protective element of the structure at every point in contact with water, from foundation insulation to rainwater gutters, from wet areas to swimming pool insulation.

4. Polyurethane Decorative Coatings

Polyurethane coatings, which are indispensable for decorative applications, can show various visuals in 3D dimension by adding depth where they are applied. Such coatings are frequently used in showrooms and indoor bathrooms.

Application Techniques for Polyurethane Coatings

The correct and effective application of polyurethane coatings directly impacts their performance and durability. These coatings can be applied to surfaces using three main methods: trowel, roller, and spray. Each method offers different advantages and areas of application.

Trowel Application: A trowel is the most suitable tool for applying polyurethane flooring evenly and homogeneously on the surface. This method can introduce air bubbles during application, which should be removed afterward using a spike roller. The spike roller also helps improve the distribution of self-leveling polyurethane coatings across large areas.

Roller Application: Rollers enable the quick and efficient application of polyurethane coatings over large surfaces. Using a roller helps to evenly distribute the coating and speeds up the application process. This method is particularly preferred for large areas and flat surfaces.

Spray Method: The spray method is the best option for applying polyurethane coatings quickly and uniformly on large and irregular surfaces. It allows the coating to spread as a thin layer, improving the quality of the coating.

Each application method offers advantages for specific situations and needs. Choosing the right method maximizes the aesthetic and performance characteristics of the coating while optimizing the application process. Therefore, the type of surface, area of application, and desired results should be considered when selecting the most appropriate method.
