| Abstract: | CONCLUSION. With the comparison of analysed properties of leaf casled coated paper samples we examined the effect of starches and methylcellulose surface coatings on some typical physical properties used in paper testing. From the results conducted during the research we may be able to conclude that: - Not all starches arc suitable for surface coating application in the paper conservation lcafcasting procedure. - Potato starch coating (sample 1) show improved properties, but because of its great adhesion it is not adequate as coating during the lcafcasting. - Corn starches coatings (Sample 3 and 4) show no improvement on treated paper samples. - Wheat starches (Samples 2, 5 and 6) show the best results among analysed starches. - Starch and MC coatings improve paper formation. - MC, compared to starches improves some surface properties especially the hidrophobicity (contact angle) and the porosity of paper. - MC coated samples show the best results in folding endurance (double folds). |
