Bomar™ BRC-843S 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 a functional, non-yellowing, protective single-coating that extends the substrates use-life. BRC-843S is a softer and more flexible version of BRC-843. This oligomer is also tougher then BRC-843. The low water absorption and alkaline resistance make this oligomer perfect for specialty applications in the following industries: aerospace, appliance, automotive, electronic, coatings & inks for steel, plastic, glass and medical device.
