Molding in a fixed prosthesis is one of the most important stages rehabilitative treatment, as it there that attempts are made to reproduce dental preparations and adjoining regions by using appropriate materials techniques. Among molding available on market, elastomers stand out, which polymers where prey occurs through increase chain establishment cross-links. The objective study present clin...

Silane terminated prepolymers for adhesives, sealants and coatings are of great industrial importance. They very important because their low toxicity over polyurethanes, silicones, solvent-based products. Hence, many pieces literature which deal with the synthesis, properties applications this polymers hybrid system exist. Silylated polyether (MS polymers) Polyurethane Polymers (SPUR) bases num...

Mixtures of silicone elastomer and silicone oil were prepared and the values of their Young's moduli, E, determined in compression. The mixtures had volume fractions, [Formula: see text], of silicone oil in the range of 0-0.73. Measurements were made, under displacement control, for strain rates, [Formula: see text], in the range of 0.04-3.85 s(-1). The behaviour of [Formula: see text] as a fun...

The aim of this study was to determine quantitatively and qualitatively the inorganic particle fraction of commercially available dental elastomers. The inorganic volumetric fraction of two addition silicones (Reprosil Putty/Fluid and Flexitime Easy Putty/Fluid), three condensation silicones (Clonage Putty/Fluid, Optosil Confort/Xantopren VL and Silon APS Putty/Fluid), one polyether (Impregum S...

This article reviews the applications of silicone resins as ceramic precursors. The historical background of silicone synthesis chemistry is introduced to explain the production costs and supply availability of various silicones. Thermal degradation processes of silicones are classified in terms of the main chain structure and cyclic oligomer expulsion process, which determine the resulting cer...

The peaks are not column bleed. Column bleed is a continuous stream of stationary phase degradation products eluting from the column. Column bleed is a component of the baseline and not a series of peaks. Column bleed increases with temperature, especially at temperatures near the column’s upper temperature limit. When temperature programming up to the upper temperature limit, a rise in the bas...
