Température de transitionIndex. décimale : 667.9 Revêtements et enduits Résumé : Transition temperature microscopy (TTM) is a novel local thermal analysis technique that maps spatial variations in thermal properties on length scales from millimeters to nanometers. Traditional bulk thermal analysis provides a sample averaged result and cannot generally supply sufficient information about complex structures or heterogeneities within films or coatings. There currently exists a nanoscale thermal analysis (nano-TA) technique in which a nanoscale thermal probe heats a localized region on the sample surface to measure its thermal properties, including thermal transition temperatures like crystalline melting points and glass transitions. TTM enables these nano-TA measurements to be carried out rapidly at a succession of points, thus creating automated high-resolution spatial maps of the thermal properties of a sample. In this article we also demonstrate how TTM can be used to characterize chemical and structural heterogeneities and thereby generate vital information in applications ranging from coating defects, to in-situ property measurement of individual layers in multilayered films, to the detection of gradients and interfaces.

Transparence (optique)Index. décimale : 667.9 Revêtements et enduits Résumé : A series of polyester polyols were synthesized using 1,6-hexanediol (HDO), 1,4-cyclohexanedimethanol (1,4-CHDM) and trimethylol propane (TMP), alone or in combination with 1,4-cyclohexanedicarboxylic acid and adipic acid. The polyester polyols were reacted with isocyanate trimers to form polyurethane (PU) coatings. Physical properties of the polyesters such as hydroxyl value, acid value, molecular weight, viscosity, and glass transition temperature (T g) had been determined, and the IR spectroscopic analyses of polyesters/PU were reported. The properties (impact resistance, film flexibility, hardness, optical transmittance, chemical resistance, water absorption, thermostability, and phase separation) of the PU coatings so prepared were characterized. The viscosities of polyester polyols were dependent on the structure of the alcohols. Polyester polyol containing only linear aliphatic diol (HDO) was a transparent liquid at room temperature. The viscosity was increased by raising the molar ratio of 1,4-CHDM and/or TMP. All PU coatings had excellent flexibility, impact resistance, and hardness. The coatings derived from diol CHDM had the highest hardness, and the PU derived from diol HDO had the lowest hardness. The chemical resistance and water absorption improved with greater molar ratios of 1,4-CHDM or TMP. Results of differential scanning calorimetry and wide-angle X-ray diffraction indicated that there was no obvious crystallinity in the PU networks. Dynamic mechanical analysis (DMA) results revealed that both CHDM and TMP can increase the T g of PU, and the crosslinking density improved with increased molar ratio of TMP. Atomic force microscope (AFM) and DMA analysis revealed that the PU coatings had no obvious microphase separation, which enabled them to have excellent properties, and the different composition in polyols did not have significant influence on transmittance in the visible region. Results of thermogravimetric measurements indicated that all the PU coatings had good thermal stability.

Traîtements de surfaceIndex. décimale : 667.9 Revêtements et enduits Résumé : There has been a significant market of general purpose epoxies which should have good performance with cost effectiveness. Fly ash is a waste product of industry and is a pollutant thus adding the same to polymer gives extra cost effectiveness in the matrix system. Epoxy resin is chosen four our present study owing to its exceptional combination of properties such as easy processing, high safety, excellent solvent and chemical resistance, toughness, low shrinkage on cure, good electrical, mechanical and corrosion resistance with excellent adhesion to many substrates. Phenalkamines are a distinct range of natural epoxy curing agents which offers good flexibility, adhesion, moisture tolerance and non blushing properties. Surface treatment is primary carried out by silane coupling agents to check their effectiveness in improvement of performance properties.

Usure (mécanique)Index. décimale : 667.9 Revêtements et enduits Résumé : For many coatings technologists today, tribology is just a word-and one with a vague meaning at that! It is the avowed purpose of this short paper to: Alert polymeric coatings technologists of the potential importance of tribology and tribochemistry to their innovative R&D work; and stimulate the study, by these coatings technologists, of the tribological and tribochemical factors applicable to the design, preparation, and uses of organic coatings.
