Application:

SASOLATE® BG is used chiefly as a paint additive in the form of a highly effective flow agent because of its very low volatility. In amounts of 3-5% it gives nitrocellulose lacquers excellent gloss and smooth flow properties. To produce a higher gloss, the amount of BG in leather lacquers based on nitrocellulose can be increased. Because of its faint odour BG is also used in brush-applied paints.

It can be added to cellulose acetate paints, alkyd resin and oil paints to prevent blushing at high relative humidity. The occasionally severe wrinkling of various oil paints can be largely prevented by an addition of 1-2% BG. The addition of BG as a high-boiling solvent to stoving finishes effects uniform flow of the paint film. It is also employed in the manufacture of printing inks, where extremely faint odour, high boiling point and low volatility are of particular importance. The high dilatability of BG has a beneficial effect in all applications. It lowers the minimum film-forming temperature of polyvinyl acetate dispersions. When BG is added, it might happen that initial thickening occurs as a result of partial dissolving of the polymer particles; slow addition is therefore recommended. Furthermore it is advisable first to emulsify BG with an equal quantity of water.
