Use of Q-U-V to Predict the Edge Compatibility of Commercial Sealants with Laminated Glass

Source

An important factor to be considered when commercial sealants contact the edges of laminated glass is that of the compatibility of the sealants with the polyvinyl butyral (PVB) interlayer. Lack of compatibility with sealants, which is manifested by visible narrow edge-band defects in the laminates, is more detrimental to the aesthetic than to any of the other functional properties of these laminates. For the most part, however, the functionality of sealants is unaffected by these compatibility problems since they are created by the by-products of the normal curing reaction of the sealants. The information presented here is aimed at helping laminated glass users make more informed judgments regarding the selection of sealants. It uses mainly the Q-U-V laboratory accelerated weathering tester to predict these compatibility problems.
