Binder requirements

Binders and Resins. The choice of binder is the most important ingredient choice in the formulation process because the binder affects the performance properties of a paint more than any other single ingredient (3). The physical properties of binders required for paints include the abiHty to dry or cure under various ambient conditions, good adhesion to various substrates, abrasion resistance, washabiHty, flexibiHty, water resistance, and ultraviolet light resistance. The balance of these required properties is mosdy dependent on whether the paint is being developed for interior or exterior appHcations. 

In chromatographic techniques, qualitative identitication of organic binders requires quantitication of species obtained from the original polymeric materials amino acids from proteins, fatty acids from drying oils, or monosaccharides in plant gums. 

The VMA appears to indicate the approximate volume of binder required for a mix. Increasing or decreasing the binder content did not produce a consistent variation of strength. 

Interlocking construction blocks are also a promising field for sulphur concretes. The various types of blocks produced allow easy construction. The close reproduction of mould shape is a major advantage mortarless construction has been employed, allowing use of unskilled labour. Improvements in mix design should lead to a reduction in the quantity of binder required and thus a reduction in cost. 

It should be noted that a new technique has been developed to cast large grains of solventless double-base proplnts for rocket motors. This means that in future it will not be always necessary to use composite proplnts in prepn of large rocket proplnt grains Refs l)Anon, "The Preparation and Testing of Explosives , Summary Technical Report of Division 8, NDRC Vol 1 (1946), 93ff la)W.

The art of mixing various size fractions is empirical, aimed at minimizing the amount of binder required to produce an adequate density. As a rule, binder requirements increase with decreasing size of filler particle. 

On the other hand, there are two groups or systems for various nutrients and metabolites in which transport of certain metabolites postulated to be driven directly by the hydrolysis of ATP or other energy-rich compounds without the requirement of a protonmotive force these are the binder -requiring systems and the phosphotransferase systems [22]. Binders are periplasmic proteins, which occur between the cytoplasmic and the outer membrane of microorganisms. They appear to be loosely attached to the outer face of the cytoplasmic membrane, from which they can be removed, for instance, by mild osmotic shock. However, the mentioned hypothesis that the (shock-sensitive) binder systems of active transport are primary active does not appear to be fully established mainly because a distinction between primary and secondary active transport is not possible in the presence of a functioning H -transporting ATPase. The main evidence in favor of primary active transport in shock-sensitive transport systems has been derived from a Ca, Mg, ATPase-less mutant of E. coli. There are, however, some findings which do not seem to support this hypothesis. 

Heterodisperse extenders have a smaller binder requirement than homodisperse extenders because their interstices can be filled with fine particles. In homodisperse systems the binder penetrates the interstices.

Sulfite liquor is a by-product obtained during the treatment of wood with sulfites (calcium, sodium, magnesium, and ammonium) to produce cellulose. The liquor has significant adhesion properties, thereby fulfilling one of the binder requirements.
