In the paint and coating industries, paint adhesion testing is often used to determine if the paint or coating will adhere properly to the substrates to which they are applied. Several tests measure the resistance of paints and coatings from substrates: cross-cut test, scrape adhesion, pull-off test , and others.
A test patch should be as clean as possible. Contamination of a patch can influence the results significantly. Bresle patch injected with 15ml water as in ISO 8502-6 Annex A. The ISO 8502-6 standard prescribes in annex A that certified patches shall be used. This annex describes a stress test to ensure patch adhesion and wash ability.
Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction. [3] Soil porosity consists of the void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colour are self-defining.
In laminated composites, the adhesion between layers often fails first, causing the layers to separate. [6] For example, in fiber-reinforced plastics , sheets of high strength reinforcement (e.g., carbon fiber , fiberglass ) are bound together by a much weaker polymer matrix (e.g., epoxy ).
