Abstract
The transparent fire-resistant glazing has at least two glass or glass ceramic panes with a gap between them, which is filled with a UV-cured material. It is made by curing a UV-curable material filling the gap with UV radiation. The UV-curable material includes polymerizable components, namely a monomer with acrylate functionality and an oligomer, and at least one bromine-containing flame retardant. The fire retardant can be a polybrominated diphenyl ether, a brominated alcohol, or a polybrominated cycloalkane, and/or a mixtures thereof. The glazing is made by a process in which the panes are cleaned and masked to form the gap between them, the UV-curable material is filled into the gap and then cured with the UV radiation.
