Bomar Oligomers® BRC-843SD1

1 of 88 products in this brand

BRC-843SD1 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, nonyellowing, protective single-coating that extends the substrates use-life. BRC-843SD1 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, and medical device.
