Figure 1From: The effect of a new formaldehyde-free binder on the dissolution rate of glass wool fibre in physiological saline solution Large binder droplets at different times in the dissolution process. Optical micrographs of two large binder droplets from sample 2 at four different times in the dissolution process showing changes in morphology as the dissolution proceeds. The red arrow marks a typical measurement location for fibres in large binder droplets. All micrographs are at the same magnification.Back to article page
