Urethane acrylates and urethane methacrylates are essential components in high-performance UV and EB curing formulations. RAHN offers a comprehensive range of both chemistries, each engineered to meet specific performance and production requirements.
Acrylate Advantages: Urethane acrylates provide excellent flexibility, broad substrate adhesion, and cost efficiency, making them perfect for coatings, adhesives, and inks requiring excellent adhesion to a wide range of surfaces.
Methacrylate Advantages: When comparing the same chemical backbone, urethane methacrylates offer enhanced thermal stability exhibiting higher Tg, a stiffer, tighter crosslinked network but with reduced cure speed. These changes can offer distinct formulation properties that can support demanding UV/EB curing systems. These advantages make urethane methacrylates particularly useful for applications that require specific performance profiles, controlled reactivity, and reliable thermal properties. Depending on the application, whether it's printing inks, industrial coatings, adhesives, or 3D printing, UV coatings for wood, RAHN’s urethane acrylates, polyester acrylates and methacrylates deliver flexibility, adhesion, durability, and resistance to heat and chemicals. These products are designed to provide flexibility, adhesion, durability, and excellent resistance to heat and chemicals. For instance, GENOMER* 4267, a urethane acrylate oligomer, combines flexibility and hardness with excellent adhesion, particularly on plastics. Urethane methacrylate options, like GENOMER* 4205, offer low viscosity and balanced performance properties, making them ideal for applications where flexibility, processability, and durability are essential.
