The structure of the prepared latex film was characterised and analysed by FTIR and XPS. The effects of the addition of silicone monomer on the latex film and the application properties were investigated by SEM and TG. The results showed that: both the organic fluorine and the silicone monomers participated in the polymerisation, and the particle size of the emulsion was 50-70nm. XPS showed that the fluorine and silicon elements in the film-air interface were 1.74% and 3.12% higher than the theoretical values. SEM showed that the surface microstructure of the latex film of the fluorosilicone copolymer emulsion was relatively rough, and the roughness was helpful to further improve the hydrophobicity and antifouling property of the finished leather. TG showed that, after the addition of silicone monomer, the heat resistance of the film was obviously improved. Compared with fluorinated polyacrylate emulsion, the contact angle of the leather sample finished by organo fluorosilicone polyacrylate emulsion to water increased about 7°. The applied properties of the finished leather were also improved.

It has been demonstrated that colloidal polymeric particles can be successfully used for the deposition of different functional nano-materials. Due to their numerous attractive properties polymeric particles have been used as templates for the the synthesis, storage and transportation of nanostructured materials. This contribution reviews the important developments in the area of composite particles over the last decade and is limited to the polymeric particles operating in the aqueous medium. The synthesis, characterization and applications of hybrid particles are discussed in details. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=3516

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Improving dirt pickup resistance especially in waterborne coatings is critical to future coating innovations. This review article focuses on the development of a coatings with improved dirt pickup resistance, with seems to be continues important goal in the coatings industry. The basic demand for this is due to the growth in "softer" elastomeric wall and roof coatings which demands low-VOC formulations and with traditional emulsions it results in tackier coatings due to reduced glass transition temperatures (Tgs). If we consider the current scenario of Asian continent, there are a huge number of high-rise commercial buildings constructions are planned, which is driving the need for coatings that are easier to clean and maintain.
Different processes of emulsion preparation such as post (room temperature) crosslinking and inorganic organic hybrid emulsion, which facilitate the cleaning of coating by water are been discussed. It also draws a brief idea on the possible applications of the same with different paint formulations.
This paper explains the terminology Dirt Pickup Resistance, laboratory test method to measure the same, newer challenges for Paint industry regarding DPUR & how the DPUR fora paint can be improved.Note de contenu : - Mechanism of dirt pickup on latex paint films

The performance of the coalescent was evaluated in terms of film formation quality and impact on final paint properties, compared to a commercially available petrochemical coalescent. Results demonstrated that it is possible to achieve better properties in terms of paint film quality with an optimised environmental profile using the newly developed bio-based coalescent.

ViscositéIndex. décimale : 667.9 Revêtements et enduits Résumé : The influence of liquid pressures and orifice diameters on the sprayability of non-Newtonian, waterborne latex coatings, that vary in latex particle size and thickener composition are examined in this study. It is observed that the higher the dynamic uniaxial extensional viscosities (DUEVs, ηe) of the coatings, the larger the Sauter mean diameters (SMDs) of the spray droplets and the broader the droplet size distributions. The shear viscosities at high shear rates and the parameter reflecting shear elasticity, the storage moduli, at low deformation rates do not correlate with the droplet sizes and the distributions observed. In addition to these observations, the Sauter mean diameters of spray droplets decrease with increasing spray pressures and with decreasing orifice diameters; however, with increasing pressures, pulsations in the fluid due to turbulence create areas of high and low droplet density.The relationship of the SMD to orifice diameters using fan nozzles is defined by the relationship:[FORMULA]The experimental results associated with each of these parameters are discussed in the text.
