| Résumé : |
The opportunities for using nuclear processes for the benefit of mankind are numerous as a nearly unlimited source of energy and it finds applications in various fields comprising medicine, biology, chemistry etc. One ofthe peaceful uses of nuclear energy is in the field of analytical chemistry. Development of radioanalytical techniques like neutron activation analysis, isotope dilution methods, tracer techniques and radiography have helped to characterize coating materials and to carry out research in related fields. The methods enjoy advantage like specificity, sensitivity, good accuracy and widespread applicability. Their applications include measurement of water permeability of coatings, determination of plasticizer's retention, adsorption of driers in paints system, measurement of film thickness, uniformity and porosity of paint films. These techniques have been also used in the areas of weathering measurements of emulsion paints and short listing of microbial inhibitors of wood finishes and ionic penetration from paint films. The increasing acceptance of this technique will add a new and powerful tool for practising paint technologist. |
