A NEW METHOD OF LINING OIL PAINTINGS USING POLYURETHANE

Abstract

Mechanical factors that affect oil paintings like scratching, shaking, percussion, tapping behind the Can

vas easel will affect the oil painting layers including painting layer, On the other hand, the materials used in

lining oil paintings such as glue, wax or synthetic resins do not prevent or reduce the resulting deterioration

caused by previous factors, so there was a necessity for searching for a substance that reduces the previous

deterioration sorts. In this study, the experimental research goal is shown to compare this material with the

materials used in lining. Samples of linen and cotton fabric were made, lining them with four adhesive mate

rials, the work of industrial obsolescence, measuring the resistance of these samples to the tensile strength

and elongation and strength of puncture and flexion. The processes were monitored by Electron microscope

scanner used before and after the industrial limitation and image. The results showed that polyurethane,

which was compared with the rest of the other lining materials, is more resistant to the mechanical forces

that affect the oil paintings. The case study was done on ancient oil paintings, from a collection of the Mo

hammed Ali Museum in Egypt. It is an antique painting dating back to 1898, where the experimental results

were applied and can be lined with a new material (polyurethane).
