| Résumé : |
Paint coatings are used widely to protect metal and non-metal surfaces apart from giving them aesthetic appearance. A protective layer is expected to withstand the varying environmental conditions which cause changes in its structure and eventually lead to its failure in service. Among the prime properties, adhesion of a coating to the substrate is considered to be an important one. It is evident that however excellent the other properties of the paint coating may be, its protective function would not be fulfilled if it does not have adequate adhesion to the substrate. Several factors which contribute to the adhesion of a paint coating are nature of substrate, surface preparation/pretreatment, composition of the resin used as binder, nature of the solvent used, viscosity and applications of the paint and thickness of the coating. The influence of these parameters on adhesion of paint coatings to metal substrate has not been fully established, yet. In an attempt to generate practical information about them, the following aspects have been studied : i) The influence of acid value and hydroxyl value of the resin used as binder. ii) Effect of surface preparation and pretreatment. iii) The variation in adhesion strength with thickness of the paint coating. iv) The level of pigmentation and part replacement of prime pigments by extenders/fillers. v) The bond strength of paint coatings to metal substrates. In the present study the Direct Pull Off Technique was used for measuring the practical adhesion of paint coatings. |
