BRC-843D
BRC-843D: Difunctional Aliphatic Hydrophobic Urethane Acrylate
BRC-843D is a difunctional, hydrophobic urethane acrylate which can be formulated to be used 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 absorption and alkaline resistance make this oligomer perfect for the following industries: aerospace, appliance, automotive, cosmetic, electronic, industrial, medical device, metal finishing, and UV-curable inks & coatings. BRC-843D exhibits retention of mechanical properties after exposure to high temperatures (200°C for 30 minutes). In addition to the adhesion properties listed in the table below, BRC-843D also shows excellent adhesion to ABS, PVC, PMMA, and Polystyrene.
