Brush tip for application of medium to low viscosity fluids. 0.43mm apeture.
Brush applicators are ideal when working with solvent based adhesives that rely on evaporation. When working with Paraloid B-72 in acetone as a consolidant, for instance, you are likely to encounter two problems by having an open pot which you dip your brush into. Firstly, the solvent will evaporate (slowly), increasing the concentration of the solution over the time you're using it. Secondly, this form of application helps prevent reverse migration - a constant stream of solute rather than an intermittent one is more likely to penetrate deeper.
