BRC-843D is a difunctional, hydrophobic urethane acrylate which can formulated to be in heavy—duty industrial and commercial applications. The resulting tough film makes an effective, non-yellowing, protective single coating that extends the substrates use-life. The low water and alkaline resistance make this oligomer perfect for the following industries: aerospace, appliance, automotive, cosmetic electronic, industrial, medical device, metal finishing, and IN-curable inks 8 coatings BRC-843D exhibits retention of mechanical properties after exposure to high temperatures (200T for 30 minutes). In addition to the adhesion properties listed in the table BRC-843D also shows excellent adhesion to ABS, PVC, PMMA and polystyrene.
