Coating defect: circular voids or separation in the coating. Fish-eyes can be caused by oily spots or silicone particles and/or by air-borne droplets that are deposited on the painted surface.

(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.

Relatively small deformations (pock-marks) in an applied film caused by the entrapment of air between layers.

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.

Small craters which will appear in the paint if silicone or wax has not been removed from the panel being sprayed.

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.

Term commonly used to describe the small lens-like blemishes sometimes found in dipped goods. Such blemishes often arise from silicone based emulsions used as anti-foam or anti-webbing agents.

Blemishes, in circular form, which cause deformation of printing, coating, laminating, etc.

Areas on a steel fracture surface having a characteristic white crystalline appearance.

Circular areas devoid of topcoat caused by the wet paint "drawing" in on itself due to surface contaminants such as oil or silicones or a general incompatibility of paint and sealer.

A scalloped surface on a finished product surface.

Defects in the finish film caused by surface contamination (usually from oils, silicones, and waxes.)

A scalloped surface on a shrink film package. The defect has the general appearance of rounded or oval areas that have not been completely shrunk.

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.

Round or eye-shaped deformations in a coating (adhesive, release, protective, etc.); craters.

The circular or oval patterns that remain on a package that has been poorly shrunk. They are normally associated with the absence of adequate heat or air velocity.

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.

Also called cat's eyes, this weld defect has a hole or piece of matter surrounded by a circular area of brightness while a paint defect shows has the circular area of brightness surrounding spots.

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.
