This standard defines terms used in the field of coating materials (paints, varnishes and raw materials for paints and varnishes).
Terms relating to specific applications and properties are dealt with in standards concerning those applications and properties, e.g. corrosion protection, coating powders.
Terms on nanotechnologies in this standard are harmonized with ISO/TS 80004-4.
Note 1: Those terms that are defined elsewhere in this International Standard are shown in boldfaces.
Note 2: See also the ISO online browsing platform (OBP): (https://www.iso.org/obp/ui/)
2 Terms and Definitions
2.1
abrasion
process of wearing away or deformation of a surface by friction as a result of rubbing
2.2
abrasive blast-cleaning
impingement of a high-kinetic-energy stream of an abrasive on the surface to be prepared
2.3
accelerator
additive that increases the speed of chemical reactions
2.4
acid value
number of milligrams of potassium hydroxide (KOH) required to neutralize 1 g of a sample under specified test conditions
2.5
acrylic resin
synthetic resin resulting from the polymerization or copolymerization of acrylic and/or methacrylic monomers, frequently together with other monomers
2.6
additive
any substance, added in small quantities to a coating material, to improve or otherwise modify one or more properties
2.7
adhesion
phenomenon of attachment at the interface between a solid surface and another material caused by molecular forces
Note: Adhesion should not be confused with cohesion.
2.8
adhesive strength
force required to detach a coating from a substrate or another coating
2.9
aerosol
solid or liquid particles in dispersion in a gaseous medium
2.10
after tack
property of a film to remain sticky after normal drying or curing
