Urethane acrylates are produced by the direct addition of hydroxyalkyl acrylate and polyols to diisocyanates or polyisocyanates. Variables for adjusting the UV reactivity of the coating and the properties of the cured coating, apart from the chemical nature of the used diisocyanates, polyisocyanates, and polyol components, are the molecular weight, the double-bond functionality, and double-bond density
Urethane acrylate oligomers derive their properties of tensile strength, elongation, hardness, weather ability, adhesion, etc from the interplay of polyol and isocyanate selection with the added minor complexity of acrylate end groups.
As with thermally cured urethanes, urethane acrylate oligomer properties can range from the hard materials commonly used in wood coating to the soft, tacky, elongative materials used in film laminating and pressure sensitive adhesives.
Urethane acrylate is a type of polymer material that is commonly used in various industrial and commercial applications. It is known for its high resistance to abrasion, impact, and chemicals, making it a durable and long-lasting material.
Some of the common uses and application methods of urethane acrylate include:
Coatings: Urethane acrylate is often used as a coating material in various industries such as automotive, aerospace, and marine. Urethane acrylate can be applied as a coating on various surfaces, such as wood, metal, concrete, and plastic, to protect and improve their durability
Adhesive: Urethane acrylate is used as an adhesive in construction and other industries due to their high strength and durability it can be applied using methods such as brush, roller, spray, or injection
3D Printing: Urethane acrylate is used as a material for 3D printing due to its excellent mechanical properties and ability to produce high-resolution parts. It is typically applied using a process called stereolithography, which involves curing the material layer by layer with a UV light.
Cast Elastomers: Urethane acrylates are also used to create cast elastomers which are high-performance materials used in various applications such as sealant, gaskets, and other components.
Medical Devices: Urethane acrylates are used in the manufacture of various medical devices due to their biocompatibility and ability to withstand sterilization
Injection molding: Urethane acrylate can also be applied in the process of injection molding to produce various products, such as automotive parts, toys, and consumer goods.
Urethane acrylate is a type of polymer that offers
several benefits, including:
Durability: Urethane acrylate is known for its toughness and resistance to abrasion, making it ideal for applications that require high levels of durability.
Chemical resistance: Urethane acrylates are resistant to a variety of chemicals, including fuels, oils, and solvents, which makes them suitable for use in harsh chemical environments.
Flexibility: Urethane acrylates have excellent flexibility, allowing them to be used in applications that require bendability and flexibility.
Weather resistance: Urethane acrylates have good weather resistance and are able to withstand extreme temperature changes and exposure to UV light.
Adhesion: Urethane acrylates have good adhesion properties, allowing them to bond well with a variety of surfaces, including metals, plastics, and wood.
Optical clarity: Urethane acrylates have excellent clarity and can be used in applications where transparency is important, such as in the manufacture of optical lenses and displays.
Growing innovation in UV/EB curing technology allows urethane acrylate oligomers to replace urethane prepolymers in many applications. These applications include in place gaskets, optical films, thick section coatings and industrial floor coatings. The environmental benefits lower toxicity and regulatory compliance factor into the drive for replacing urethane prepolymers. This trend makes UV/EB technology a growing presence in the marketplace.
