An adhesive that can withstand elevated temperatures is necessary for the conservation of artifacts in hot climates. The use of Butvar B-98 as a modifier to raise the glass transition temperature of Paraloid B-72 was investigated. The characteristics of B-48N and B-72 blends, currently in use in the field of conservation, were used as a comparison for analysis of the B-98 and B-72 blends. Differential Scanning Calorimetry (DSC) was used to determine the glass transition temperatures (T-g) of the blends and shear testing was used to investigate the shear strength of the blends. While the B-98 and B-72 blends attained elevated glass transition temperatures and performed well during shear testing, issues regarding miscibility and phase separation of the blends were investigated using transmission FTIR, DSC, and optical microscopy.
