Résumé : |
The esterification of Lac with rosin (Abietic acid) was investigated for the preparation of Rosin modified Lac resins. Four different compositions were tried at 200-220°C. The products obtained were found to have excellent film properties with smooth 8 glossy finishes. They were also having excellent resistance to water, chemical 8 solvents. 1:3 weight ratio of lac: rosin was found to give superior results. These rosin modified lac resins were also utilized for the preparation of gloss paint. The paints were found to have excellent film properties with smooth 8 glossy films. All the samples showed no corrosion for 8 days in humidity chamber. |
