Continuing the company’s ongoing commitment to provide customers with the high-performance solutions they need to create market-leading products, Sartomer announces 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.
CN9030 is resistant to harsh chemicals, such as methyl ethyl ketone (MEK), and exhibits excellent gloss retention. Additional applications for this high-performance oligomer include inks (lithographic, flexographic, screen and inkjet), laminating adhesives and electronics.
“The performance bar for UV/EB-cure coatings is continually being raised, and it’s getting much harder for formulators to keep their edge,” said Nikola Juhasz, Sartomer’s senior director of global R&D. “That’s why we work with our customers to develop oligomers like CN9030. This product was designed to deliver the flexibility, weatherability, adhesion and corrosion resistance required to create leading products for the most demanding applications.”
