Abstract:

In this study, the properties of traditional natural adhesives, water-based adhesives, synthetic and semisynthetic adhesives, which are still in use today in oil paint conservation and restoration, were considered. Natural animal adhesives and glues which are rabbit glue, gelatin, isinglass glue and fish glue, etc. have been used for a very long time in oil painting conservation and restoration. Water-based adhesives include funori, rice and wheat starch. Starch is preferred in oil-painting patch making for torn areas, since it is a widely available and cheap material. The use of synthetic adhesives has increased with the development of the chemical industry. The varities of synthetic adhesives used in oil-painting conservation increase continuously. The most frequently used synthetic adhesives are EVA-based adhesives and Cyclodecane. Cellulosederivatives and ethers, methylcellolose MC and carboxyl-methylcellulose CMC, which are called semi-synthetic adhesives, have been used since the 1950s in those works. Ethylose and hydroxypropyl cellulose clugel are used. In this paper, the positive and negative properties of the adhesives often used in oil-painting conservation are also examined.
