(1) A paint defect which manifests itself by the crawling of wet paint into a recognized pattern of small dimples. (2) A small globular mass of material not fully dispersed into the bulk system. Most evident in transparent formulations, most often caused by the incomplete dispersion of rheology modifying materials, such as fumed silica.
Small circles that appear in a floor finish after it has dried. This can be caused by applying too heavy of coats of finish or by too much agitation during the application. Another name for this is birds' eyes.
Defects in a coating film, circular in shape, usually resulting in contamination of a substrate surface. The coating material will not wet this surface, and, as a result, will pull back, exposing the substrate. May vary greatly in size and distribution. Frequently resembles Craters.
A surface depression or crater in the wet paint film. Fish eyes are caused by repulsion of the wet paint by a surface contaminant such as oil or silicone. The depression may or may not reveal the surface under the paint.
Also called cratering, crawling, holes, spots or flow marks. When caused by surface contaminants the finish is applied over areas in which the wetting agents cannot perfo rm their function. The finish then recedes away from this area reforming into the film. This “crawling”creates round or elliptical areas lacking adequate finish. May also be caused by failing to properly agitate a finish prior to application.Without proper agitation properties within the finish may separate.The flattening and wetting agents will therefore not be in proper concentration and cause this appearance.
A type of surface separation of a floor coating. These occur when the liquid application pulls away from a speck of dirt or when applying over an oily or contaminated surface. The resulting appearance resembles fish eyes, fish scales, snake skin, etc.
coating defect consisting of undissolved particles in the coating usually surrounded by a circular crater. The particles are usually resinous and are raised up from the cured surface with the appearance of the eye of a fish.
