Essential Uses for Polyurethane Form

The applications of polyurethane span across multiple industries and fields, with the majority being presented in the industry. Polyurethane coatings are also derived from polyurethane raw materials, thereby having an extensive application scope.

Aerospace

Aerospace vehicles are exposed to extremely harsh conditions, encompassing high UV radiation, drastic temperature variations, and erosive and abrasive impacts from rain and sand during high-speed flights. Precisely, polyurethane coatings possess outstanding UV resistance, weatherability, and abrasion resistance, capable of providing long-term and effective external protection for aircraft and spacecraft. Within the aircraft interiors, polyurethane foam, characterized by its lightweight, high strength, and favorable resilience, is utilized as the filling material for aircraft seats. Simultaneously, numerous devices within the aircraft frequently come into contact with corrosive chemicals like fuel and hydraulic oil. The chemical corrosion resistance of polyurethane coatings effectively safeguards crucial components such as fuel tanks and hydraulic pipelines, averting performance degradation. In conclusion, polyurethane materials play an indispensable role in the aerospace vehicle manufacturing sector and serve as a significant impetus for advancements in aerospace technology.

Automotive

It is widely acknowledged that polyurethane foam plays a crucial role in enhancing the comfort, elasticity, and support of car seats. Additionally, polyurethane materials are extensively utilized in the steering wheel, instrument panel, and interior trim components of automobiles. These components significantly enhance the luxury and durability of the vehicle interior by offering a soft touch and high abrasion resistance. These represent the applications of polyurethane foam in the automotive industry. Polyurethane coatings, on the other hand, are predominantly employed on the exterior of vehicles, such as body spraying. The high weather resistance and UV resistance of polyurethane coatings

protect the vehicle body from adverse weather conditions, solar radiation, and environmental contaminants, maintaining the vivid color and luster of the vehicle body and preventing coating cracking or aging. These coatings also exhibit excellent abrasion resistance and scratch resistance, effectively reducing exterior damage during regular vehicle usage. Polyurethane also plays a significant role in the protection of vehicle undercarriages and mechanical components. For instance, underbody protective coatings can effectively counteract corrosion and abrasion caused by salt, moisture, and gravel on the road, prolonging the service life of the vehicle undercarriage and related components. Collectively, the role of polyurethane coatings in the automotive industry is similar to that in the aerospace industry, capable of extending the vehicle’s lifespan.

Maritime Industry

Similar to the aforementioned two industries is the maritime sector. The application of polyurethane raw materials in the maritime industry is highly extensive and encompasses several distinct types of polyurethane raw materials. For instance, common soft polyurethane foam raw materials can be utilized for manufacturing seats on ships and yachts. The significant characteristic of our closed-cell polyurethane spray coatings is their ability to insulate against sound and heat. Hence, polyurethane spray materials are frequently filled in the insulation layers of ships to reduce noise during navigation and maintain a certain indoor temperature. As for the polyurethane coatings

we mentioned, they are widely utilized on ship hulls and decks due to their outstanding anti-corrosion, UV resistance, and abrasion resistance properties. Polyurethane deck coating is very important in boat maintenance work. Offshore platforms, buoys, and underwater equipment are constantly exposed to the assaults of seawater, waves, and climate. To prolong the lifespan of these devices, their surfaces are often coated with polyurethane coatings.

Construction

In the construction industry, polyurethane is highly prevalent. During construction, we typically utilize closed cell rigid foam material  on walls, roofs, pipelines, etc., for heat and sound insulation. However, many projects require polyurethane waterproof coating, for which polyurethane coatings are necessary. The waterproofing property of polyurethane coatings makes them an essential component in construction waterproofing projects. Polyurethane waterproof coatings, when sprayed onto the object surface via a polyurethane sprayer, form a continuous and seamless coating with excellent adhesion and elasticity. This effectively covers cracks on the building surface and prevents water penetration. Therefore, polyurethane coatings are widely used in

areas such as roofs, basements, balconies, garage floor and bathrooms that demand high waterproofing performance, ensuring the durability and moisture-proofing of the building structure. Hence, polyurethane is also an indispensable material in the construction industry.

Of course, there are numerous other applications of polyurethane coatings that we will not elaborate on one by one. It suffices to understand that the characteristics of polyurethane coatings include waterproofing, anti-corrosion, abrasion resistance, and UV resistance.

Make the Most of Your Polyurethane Coating

If you have already confirmed your project and procured the necessary polyurethane coatings, you might now need to know how to effectively use the purchased polyurethane raw materials. This requires customers to first acquaint themselves with the relevant equipment for polyurethane coating application and how to select the appropriate equipment. With nearly 30 years of experience in the polyurethane industry, we can recommend the most suitable solution based on customer requirements. Of course, you can also select the appropriate equipment based on the following methods.

Firstly, we need to know what equipments are suitable for the application of polyurethane coatings.

High-Pressure Airless Spraying Equipment

High-pressure airless spraying equipment ejects the coating through a spray gun under high pressure to form a uniform spray. There is no air intervention during the spraying process, hence the term “airless”. It is typically used for the spraying of one-component coatings, such as our one-component polyurea. High-pressure airless sprayers are applicable for large-area coatings on buildings, interior and exterior walls, automobiles, furniture, and metal surfaces. They offer high spraying efficiency and superior surface quality of the sprayed coatings.

Two-Component Polyurethane Spraying Foam Machine

Two-component polyurethane spraying equipment is specifically designed for spraying two-component polyurethane materials. Besides spraying polyurethane coatings, it can

also spray polyurethane insulation materials. The spray foam insulation machines use a dedicated two-component spray gun to simultaneously eject the two coating components, which are mixed in the nozzle and sprayed onto the surface. The PU paint spray machine ensures the precise proportioning of the components, averting premature curing of the coatings and achieving a more refined and durable spraying effect. Therefore, it is mainly employed in the industrial sector, particularly in applications where special properties such as high abrasion resistance and corrosion resistance are required, such as aerospace, aviation, shipbuilding, and pipeline corrosion protection.

Roller Coating Equipment

Roller coating equipment evenly applies the coating on the ground or other surfaces by manually or electrically pushing or pulling the rollers. The rollers typically come in different materials (such as carpet and sponge) to accommodate different types of coatings. Roller coating equipment is widely used in floor coating, wall coating, and furniture coating applications. Compared to spraying, roller coating equipment is usually employed for larger flat surfaces and simple coatings and features ease of operation and lower construction costs.

Coating Machine

A coating machine is a device utilized for uniformly applying coatings, adhesives, inks, etc., on various substrate surfaces. Coating machines are widely employed in industries such as paper, plastic, metal, glass, textiles, electronics, and floor coatings for the production of coatings, films, and coatings. Coating machines also encompass several different types of equipment, including blade coating machines that use a blade for coating application and roll coating machines that use a coating roll.
