Refers to a milky appearance on the surface of a paint film and is usually a result of an incorrect balance of thinners in the paint formulation or the rapid evaporation of thinners from the coating.
Coating defect: haziness of coating surfaces caused by the exudation of a component of the coating such as oil plasticizer, or noncrosslinked coating constituent when the coated part is exposed to a cycle of heat, humidity, and cooling.
Where the colour of a dried paint film appears to be hazy. Blooming is caused by moisture trapped in the film and is usually down to ambient conditions. The effect can be commonly seen with decorative paint s, where the substrate the paint has been applied to is not fully dry, or where exterior paint has been applied in damp conditions.
This defect gives a bloom or white deposit, like the bloom on a grape or plum, after the paint has dried. The cause is the rising of soluble fractions of the pigment rising to the surface on the paint's drying. The remedy for spray paints is to rub the surface down.
A thin film or milky opalescence that veils color or reduces gloss on a coat of varnish, shellac, or lacquer.
Powder-like deposit forming on the surface of the film, often resulting from partial dissolving and redepositing of pigment by a solvent component.
The time period that the Poly Iso Butylene takes to migrate to the surface of the stretch film. Once this happens high cling films are at their peak of perfection.
A haziness that develops on coated surfaces caused by the exudation of a component of the coating.
A hazy bloom to the coating surface, much like the bloom on a grape. Often associated with a reduction in gloss level.
