The Structural Conservation of Panel Paintings
Natural resins The use of natural resins as adhesives is not prevalent today; they are, however, encountered in historic objects ...
Solutions Synthetic resin solution adhesives are not widely used for fabrication in woodworking, but they remain a vital tool fo ...
Despite these qualities, the use of these adhesives in conservation is discouraged. By their very nature as cross-linking polyme ...
