The failure of paint film to adhere to its substrate. Peeling results when contaminated surfaces are painted, when there is excessive difference between paint and surface polarity or thermal expansion, or when there is solvent incompatibility.
A process in which thin flakes of matrix or mortar are broken away from concrete surface; caused by adherence of surface mortar-to forms as forms are removed, or to trowel or float in portland cement plaster.
Failure of a coating film to maintain adhesion with its substrate. Sheets or ribbons of the film detach from the substrate. The condition results from contaminated surfaces or excessive differences in polarity and thermal expansion characteristics between the surface and the film.
Removal of the corona radiata from the embryo by flushing the embryo through a syringe or pipette, or by microdissection using fine instruments. An embryo often must first be peeled before it is possible to determine whether fertilization and cleavage have occurred.
