ViscositéIndex. décimale : 667.9 Revêtements et enduits Résumé : This paper describes a study of several model bimodal particle size distribution latex systems produced by blending large and small particle size anionically stabilised latices over a wide range of blend ratios. Minimum film forming temperature (MFT), drying rate and water uptake measurements were carried out. At a 80/20 weight ratio large/small particles, a minimum was observed in the MFT and also in the extent of water absorption of latex films with short drying times, although for films dried for longer periods, no such minimum in water absorption was observed. Drying profiles fit well with existing models, except for the 80/20 I/s blend which exhibits more complex drying behaviour. Low shear rate viscosity of selected blends was measured over a range of latex solids contents. The rheological data was fitted by the Krieger-Dougherty equation which was used to calculate the maximum volume packing fraction. An 80/20 blend (large/small) was found to exhibit a higher maximum volume fraction than that of either pure component of the blend, demonstrating the better packing achievable by blending. Finally several different application areas will be discussed.

ViscositéIndex. décimale : 667.9 Revêtements et enduits Résumé : In the past, dielectric analysis (DEA) has been used as an important measurement component in the overall analysis of polymer resin systems. Much of this work has been done at the research level in determining viscosity behavior, rate of cure, and cure endpoint. In the areas where DEA has been used in the production environment, it has been in the low volume applications of aerospace composites. Within the last several years there has been an expansion of the applications where dielectric cure analysis has been used. This growth in the applications of dielectric cure analysis has expanded beyond the traditional areas of monitoring the cure of composites to include such applications as factory floor control of molding operations, monitoring resin synthesis, reduction and/or elimination of physical testing, diffusion monitoring, and SQC analysis. These applications and other techniques will be presented. Note de contenu : - Traditional cure comparison
