(1) Clouding: Varnishes, oils or thinners appear cloudy and opaque due to precipitation of insolubles.
(2) Discoloration of varnish or paint: During storage, coatings deviate from their original colors due to chemical or physical changes in certain ingredients or chemical reactions with the container.
(3) Thickening (Thickenig): During storage, the thickness of the coating is usually increased due to the loss of thinner.
(4) Thickening; Thickening; Swelling (Fattening): During the storage of colored paint, due to the chemical reaction between the components, the consistency increases (not necessarily to an unusable level), and the phenomenon of volume expansion.
(5) Liverization (Levering; Feeding): The consistency of the coating has been increased to the extent that it must be diluted before it can be used or still difficult to use. This is due to the paint base gelling or chemical reaction between the paint components.
(6) Flocculation: the phenomenon of forming agglomerates in the paint or dispersion.
(7) Gelling: The phenomenon that the coating changes from a liquid state to an unusable solid or semi-solid state.
(8) Partial crystallization: the phenomenon of local crystallization of rosin and other alcohol-soluble varnish or oil-based varnish containing rosin component during storage
(9) Skinning: The phenomenon that a coating film is formed on the co-liquid surface due to oxidative polymerization of the coating in the container.
(10) Sedimentation; Settling: Setting: The phenomenon that the solid components of the coating material sink to the bottom of the container during storage of the coating.
(11) Caking: Pigments and extender pigments in colored paint are precipitated into dense lumps which are not easily redispersed by stirring.
(12) There are coarse particles (Seedy): coarse particles (that is, a little crust, gel, agglomerate or foreign coarse particles) exhibited by the coating during storage.
(13) Pig Skin: The phenomenon that the fineness of the paint becomes poor due to flocculation of the pigment during storage.
(14) Floating: colored paint containing a mixture of different pigments, one or more pigments isolated or floated during storage or drying, and unevenly colored stripes were concentrated on the surface of the colored paint or paint And spots.
(15) Flooding: Extreme conditions of flowering. Some pigments float to the surface. Although the color of the film surface is uniform, it is obviously different from the color of the wet film immediately after application.
(16) Bubbling: The air formed during the application of the coating, the gas such as solvent vapor, or both. Such bubbles can disappear during the drying of the paint film, or they can be permanent.
