Photopolymerizable acrylic resin: Effect of curing time and temperature

A photopolymerizable resin was closely examined for its capacity as an adhe sive via cure advancement in submerged water at cold temperatures. The effe cts of curing time and temperature were studied by bond strength measuremen ts and extracted monomer quantification with high pressure liquid chromatog raphy. In both cases the cure was performed under water, and there was one wet interface. Both methods showed the progression of the photopolymerizati on with time and had similar characteristic times. The adhesion strength wa s measured by lap shear and remained nearly constant over the entire temper ature range studied (around 2 MPa for a 2-min cure), while a slight increas e in the extracted uncured monomer quantity of one of the resin components was obtained for increasing temperatures.
