- Urethane Acrylate/Isocyanate
BOMAR BR-204, an aromatic polyether urethane dimethacrylate, finds use in a diverse number of UV adhesives applications. BR-204 is valued for its strong bond strength, its affinity for glass, steel, and a variety of plastic substrates, and for its excellent elongation. BR-204 is also of value for its low initial viscosity and low color (despite its aromatic nature). It is mainly used in Primer Coatings and Glass Coatings.
