Oligomer for Weatherable Coatings with Corrosion Resistance
November 1, 2015
Sartomer has released the CN9030, a difunctional aliphatic urethane acrylate. When paired with a corrosion-resistant base coat, CN9030 can be used to provide a weatherable topcoat in high-performance UV/EB-cure coating applications. "This oligomer produces strong, flexible films and demonstrates adhesion to challenging substrates like metals and plastics," said a company spokesperson.
"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," said the spokesperson.
CN9030 is engineered to be resistant to harsh chemicals, such as methyl ethyl ketone (MEK), and is designed for gloss retention. Additional applications for this oligomer include inks (lithographic, flexographic, screen and inkjet), laminating adhesives and electronics.
