BRC-443D
BRC-443D: Difunctional Aliphatic Hydrophobic Urethane Acrylate
BRC-443D 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 substrate’s use-life. The low water absorption and acid and alkaline resistance make this oligomer perfect for the following industries: aerospace, appliance, automotive, electronics, industrial, medical device, metal finishing, and UV-curable inks & coatings. BRC-443D exhibits retention of mechanical properties after exposure to high temperatures (200°C for at least 30 minutes). BRC-443D also shows excellent adhesion to ABS, PVC, PMMA, Nylon-6, and Polystyrene.
