Shrinkage cracking of the bituminous surface of built-up roofing, or the exposed surface of smooth-surfaced roofing, in which the loss of volatile oils and the oxidation pf compounds under solar radiation produces a pattern of deep cracks with the scaly look of an alligator's hide. It occurs only in unsurfaced bitumen exposed to the weather.
Named for a pattern of cracks resembling an alligator hide. A condition of paint or aged asphalt brought about by the loss of volatile oils and the oxidation caused by solar radiation. "Alligatoring" is the result of the limited ability of paint or asphalt to expansion or contraction due to temperature changes.
Char patterns formed on paint or burned wood remains, usually in the shape of blisters. see also: Depth of Char Indicators
Coarse checking pattern on the surface of a material. Typically caused by aging, exposure to sun and/or loss of volatiles.
A visible cosmetic defect in the exposed gel coat which looks like wrinkled or alligator skin.
A characteristic of asphalt which occurs during the aging process in which the loss of volatile oils and the oxidation brought about by solar radiation produces a pattern of cracks which resemble an alligator hide, because of the limited tolerance of asphalt to thermal expansion or contraction.
A type of crazing or cracking in a pattern that resembles an alligatorâ€(tm)s hide.
Cracking in asphalt surface that resembles the belly of an alligator. Alligator cracking begins on the bottom of the pavement and is the result of deflection or bending of the pavement under wheel load or failure in the sub-grade.
lots of wide patterned cracks in the paint film, resemblig alligator scales. Usually caused by: multiple coats of oil based paints that have become brittle with age; topcoat not bonding to a glossy undercoat; insufficient drying time between coats; or a hard coating over a soft primer.
When paint cracks into large segments resembling alligator skin. Similar to "cracking, crazing or checking."
A reference to a certain failure in paint that looks similar to an alligator hide. Also known as wrinkling.
A form of paint failure in which cracks form on the surface layer only. It is caused by the application of a hard drying paint over a relatively soft paint or by the application of thick films, in which case the underlying surface remains relatively soft. It is also caused by the application of paint over unseasoned wood. As the name implies, an alligatored surface is one that resembles the hide of an alligator in that it is cracked into large segments. As the surface of the thick film dries it tends to shrink. The soft undried, bottom layers of the thick film allow the surface film to shrink thereby causing the alligatoring.
Contraction of a film forming small irregular islands of the film with cracks in between. When an overprint breaks up over the undercoat. This happens with ceramics when the undercoat is lower melting than the overcoat. This also happens when a UV curable enamel is not uniformly cured.
Surface cracking due to oxidation and shrinkage stresses, which shows as repetitive mounding of an asphalt surface, resembling the hide of an alligator. French (Crocodilage)
a form of cracking that appears on paintings in a pattern that resembles an alligator's hide.
(1) Pronounced wide cracking over the entire surface of a coating having the appearance of alligator hide. (2) The longitudinal splitting of flat slabs in a plane parallel to the rolled surface. Also called fish-mouthing.
Cracks in a paint surface, resembles alligator hide.
(extended definition) Coating defect: surface defects of a coating film having the wrinkled appearance of alligator skin.
Refers to the cracking of a painted surface
Cracked or heavily textured painting (hence the alligator skin reference).
Open cracks or fissures in the surface of a paint coating. This criss-cross pattern is caused by expansion or contraction of new top coat over a slippery undercoat.
Convex portions of a carbonized material, separated by cracks or crevasses that form on the surface of char. Commonly forming on materials such as wood, as the result of pyrolysis or burning. Also called Char Blistering.
A pattern of cracking of an approximately rectangular grid. Usually caused by differential movement of a coating and substrate..
A uniform distribution of surface cracking in a symmetrical pattern resembling the skin of an alligator.
Paint-failure condition where the paint pulls apart in a crazed line pattern resembling alligator skin. Caused by paint applied too thickly; paint that dried too quickly; or a second coat painted over a first coat that was not dry.
cracking of the surfacing on a bituminous roof or coating producing patterns similar to the hide of an alligator
A scaly pattern that appears on paint due to the inability of the paint to bond to a glossy coating beneath it. It can also be due to the application of a hard coating over a soft primer, or (with oil-based paint) because the wood was recoated before the undercoat was dry. Aluminum Paints: A paint, usually solvent-based, that contains aluminum particles and provides a metallic appearance. Applied Hiding: Refers not only to the opacity of the paint film, but also to how it hides, depending on its thickness and how smoothly it flows out. Must take into account how the paint is applied (brush, roller, spray, etc.).
The cracking of the surfacing bitumen on a built-up roof, producing a pattern of cracks that resemble an alligator’s hide. picture
A finish that exhibits large segmented cracks with the appearance of an alligator hide. May be caused by heavy coating, coating over non-cured coatings, use of fast drying thinners or the application of a finish over another with less elasticity.
Paint film cracking that makes the surface look like alligator skin.
Deep shrinkage cracks, progressing down from the surface in smooth surface membrane coatings and sometimes in bare spots of aggregate surfaced membranes. It is a consequence of hardening from the sun and air.
Surface imperfections in a coating resulting in a wrinkled appearance. Usually caused by incompatibility of a newly applied coating with an existing surface coating or sealer. Also know as orange peel or fish eyeing.
The upper paint layers pull away in a pattern similar to the look of an alligatorâ€™s hide when the drying process is compromised. The layer below is visible and the upper layer has a raised appearance. Also known as â€œdrying cracksâ€ â€“ see â€œDrying cracksâ€ for illustrations.
the cracking of the surfacing bitumen on a built-up roof, producing a pattern of cracks similar to an alligator's hide; the cracks may or may not extend through the surfacing bitumen.
Condition of paint film where surface is cracked and develops an appearance similar to alligator skin.
The crackled texturing of a painted surface akin to alligator skin. Can be intentional though usually unwanted.
A condition of paint or aged asphalt brought about by the loss of volatile oils and the oxidation caused by solar radiation. Causes a coarse checking pattern characterized by a slipping of the new paint coating over the old coating to the extent that the old coating can be seen through the fissures. "Alligatoring" produces a pattern of cracks resembling an alligator hide and is ultimately the result of the limited tolerance of paint or asphalt to thermal expansion or contraction.
The cracking in paint that results in a coarse pattern, resembling alligator skin.
Surface imperfections of a coating film having the wrinkled appearance of alligator skin. Usually caused by the applied coating reacting with or “lifting” an existing surface coating or sealer.
