Bomar™ BR-641D is a Polybutadiene (PBD) urethane acrylate, which was designed to meet rigorous electronic coating applications. This oligomer has exceptional adhesion to various metals, glass,and polycarbonate substrates. BR-641D has many desirable properties that are typical to PBD resins, combined with radiation curability. In applications requiring thermal cycling resistance, BR-641D withstands the extremes of temperature typical of such tests, without undue degradation of properties. In addition to the adhesion properties listed in the table below, BR-641D showed excellent adhesion to PMMA, ABS, PVC, Nylon-6, Polystyrene,and Polypropylene.

BRC-4421 is a difunctional, hydrophobic urethane acrylate that can be formulated into chemical and temperature resistant coatings and resins. The material has low color and excellent adhesion to a wide variety of plastics. The material can be formulated into tough, impact resistant 3D printing resinswith excellent flexibility. It’s ultra-low water absorption makes this an excellent choice for moisture sensitive or hydrophobic applications

Bomar™BR-640Dis a polybutadiene (PBD) urethane acrylate with a functionality of two. Designed to meet rigorous electronic applications, BR-640D has many desirable properties typical to PBD resins, combined with radiation curability. In applications requiring thermal cycling resistance, BR-640Dwithstands the extremes of temperature typical of such tests, without undue degradation of properties.Excellent hydrophobic properties exhibited where 0.012 and 0.037% water was absorbed by cured coating when submerged in water for 24 hours. In addition to the adhesion properties, BR-640D showed excellent adhesion to ABS, acrylic, nylon-6, PVC, and PS.

Bomar™ BRC-443 is a difunctional, hydrophobic urethane acrylate which can be formulated to be used in heavy-duty industrial and commercialapplications. 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-443 exhibits retention of mechanical properties after exposure to high temperatures (200oC for 30 minutes). In addition to the adhesion properties below, BRC-443 also shows excellent adhesion to ABS, PVC, PMMA, Nylon-6, and Polystyrene

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.
