Bomar Oligomers® BR-202

CASE Ingredients Features: Good ElongationGood Hydrolysis ResistanceImproves Adhesion
Chemical Family: Urethane Acrylate/Isocyanate

Bomar BR-202, an aromatic polyether urethane dimethacrylate, finds use in a diverse number of UV coating applications. BR-202 is valued for its strong bond strength, its affinity for glass, steel, and a variety of plastic substrates, and for its excellent elongation. BR-202 is also of value for its low initial color (despite its aromatic nature).
