Sartomer Introduces CN9030 Oligomer for Weatherable Coatings

Sartomer, Exton, Pennsylvania, has announced the release of CN9030, a new difunctional aliphatic urethane acrylate. When paired with a corrosion-resistant base coat, CN9030 can be used to provide a weatherable top coat in high-performance UV/EB-cure coating applications. This oligomer produces strong, flexible films and demonstrates adhesion to challenging substrates like metals and plastics. When tested for adhesion, CN9030 significantly outperforms typical epoxy and polyester acrylate oligomers on a variety of substrates, including aluminum, cold-rolled steel, tin-plated steel and polyethylene terephthalate (PET). Its unique combination of strength and flexibility makes CN9030 ideal for coated metal used in outdoor applications, especially where resistance to yellowing and corrosion is needed. Additional applications for this oligomer include inks (lithographic, flexographic, screen and inkjet), laminating adhesives and electronics. For more information, visit sartomer.com.
