Ammonium dimolybdate (ADM) is the inorganic compound with the formula (NH 4) 2 Mo 2 O 7.It is a white, water-soluble solid. ADM is an intermediate in the production of molybdenum compounds from its ores.
Cure monitoring is, for example, an essential component for the control of the manufacturing process of composite materials. The material, initially liquid, at the end of the process will be solid: viscosity is the most important property that changes during the process. Cure monitoring relies on monitoring various physical or chemical properties.
A range of NCO/OH eq. ratios from 1.2 - 1.6 was used. Thermal and mechanical properties of moisture cured polyurethane-urea /clay nanocomposite coatings have been studied in relationship to clay dispersion and intercalation of clay platelets in the urethane-urea matrix. [ 4 ]
In organic chemistry, neighbouring group participation (NGP, also known as anchimeric assistance) has been defined by the International Union of Pure and Applied Chemistry (IUPAC) as the interaction of a reaction centre with a lone pair of electrons in an atom or the electrons present in a sigma or pi bond contained within the parent molecule but not conjugated with the reaction centre.
RTV silicone rubbers are, however, generally expensive – especially platinum-cure. They are also sensitive to substances (sulfur-containing modelling clay such as Plastilina, for example) that may prevent the silicone from curing (referred to as cure inhibition). Silicones are usually very thick (high viscosity), and must be vacuum degassed ...
Polyaspartic ester chemistry was first introduced in the early 1990s making it a relatively new technology. [1] [2] [3] The patents were issued to Bayer in Germany and Miles Corporation in the United States. It utilizes the aza-Michael addition reaction. [4] [5] These products are then used in coatings, adhesives, sealants and elastomers. [6]
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
These applications utilize permanent antistatic agents or conductive additives such as carbon black, conductive fibers, and nanomaterials. [3] [4] An antistatic agent for the treatment for coatings may also involve an ionic liquid or a solution of a salt in an ionic liquid. [5] Indium tin oxide can be used as transparent antistatic coating of ...
