Definition of alkyds in English English dictionary

Thermosetting unsaturated polyester resins produced by reacting an organic alcohol with an organic acid, dissolved in and reacted with unsaturated monomers such as styrene [C6H5CHCH2], diallyl phthalate [C6H4(COOCH2CHCH2)2], diacetone acrylamide [CH3COCH2C(CH3)2CHCHCONH2] or vinyl toluene [CH2CHC6H4CH2] Typical applications are found in electrical uses, automotive parts, and as coatings

Resins used mostly in trim paints, inside and out, although some medium duty equipment and marine enamels employ these resins as binders Most often alkyd resins are found in vehicles employing aliphatic hydrocarbons (mineral spirits or other refined petroleum distillate) as thinner Alkyds offer good leveling properties and cure to a relatively durable film, but tend to yellow interior and embrittle with age Color and gloss exterior is only fair, and alkyds are highly prone to failure exterior on surfaces containing even moderate levels of moisture Chemically, alkyds are synthetic resins formed by the condensation of polyhydric alcohols with polybasic acids They may be regarded as complex esters The most common polyhydric alcohol used is glycerol, and the most common polybasic acid is phthalic anhydride Modified alkyds are those in which the polybasic acid is substituted in part by a monobasic acid, of which the vegetable oil fatty acids are typical

plural of alkyd

Alkyd resins are used as a binding medium for paints and as painting media for oil colours They are a development of the traditional resin oil varnishes, but they incorporate a resin that is synthetically produced instead of being a natural product They produce a durable finish with a high gloss

alkyd

synthetic resin made by the reaction of phtalic anhydride with polyhydric alcohol (forming a polyfunctional saturated polyester) and modified with fatty acids or oils According to the quantity of oil introduced ("oil length") alkyds can be classified as: - short oil alkyds - medium oil alkyds - long oil alkyds The former are used in two-pack polyurethane coatings as binders in part A (to be reacted with isocyanates, which are included in part B) The latter are commonly used in exterior grade one-pack coatings, which are often referred to as "alkyds"
