Abstract
The purpose of this research is to facilitate the use of starch paste in the restoration of paper works. Especially the works where ink and colors used are not sensitive to water. In this research, starch paste with a ratio of 3 to 1 (3 parts paste and 1 part water) was used. The use of starch paste increased the pH of the samples coated with this paste compared to the control samples without paste. The samples coated with starch paste had the lowest pH after moist-heat aging compared to other samples. The samples coated with starch paste showed the lowest amount of color changes (∆E) after moist-heat aging and light aging, respectively. The use of starch paste increased the tensile strength of the samples. After light aging and moist heat aging, the tensile strength of the samples decreased compared to the previous stage, but the tensile strength of the samples coated with starch paste increased compared to the control samples without paste. The results of the adhesion resistance test of the samples showed that the amount of adhesion of the samples decreased to a greater extent after moist-heat aging compared to light aging.
