Xerotine siccative was an oil drying agent used in the late 19th century. It is a type of terebene ; unlike standard terebenes, xerotine siccative doesn't become cloudy when mixed in an oil. [ 1 ] Replacing boiled oil, xerotine siccative was mixed with paint in order to speed up the drying process; [ 1 ] however, its use ceased when it was ...
Canisters are commonly filled with silica gel and other molecular sieves as desiccants in drug containers to keep contents dry Silica gel in a sachet or porous packet. A desiccant is a hygroscopic substance that is used to induce or sustain a state of dryness (desiccation) in its vicinity; it is the opposite of a humectant.
Silica gel's high specific surface area—around 750–800 m 2 /g (230,000–240,000 sq ft/oz) [6] —allows it to adsorb water readily, making it useful as a desiccant (drying agent). Silica gel is often described as "absorbing" moisture, which may be appropriate when the gel's microscopic structure is ignored, as in silica gel packs or other ...
An oil drying agent, also known as siccative, is a coordination compound that accelerates the hardening of drying oils, often as they are used in oil-based paints.This so-called "drying" (actually a chemical reaction that produces an organic plastic) occurs through free-radical chemical crosslinking of the oils.
Desiccation is the state of extreme dryness, or the process of extreme drying. A desiccant is a hygroscopic (attracts and holds water) substance that induces or sustains such a state in its local vicinity in a moderately sealed container. The word desiccation comes from Latin de- 'thoroughly' and siccare 'to dry'.
Rapid drying, which occurs in sunny environments, results in widely spaced, irregular mudcracks, while closer spaced, more regular mudcracks indicate that they were formed in a shady place. [8] Similar features also occur in frozen ground, lava flows (as columnar basalt ), and igneous dykes and sills .
Drying agent may refer to: Desiccant, which absorbs water or moisture from its vicinity; Oil drying agent, which speed up the hardening of oils, often used in painting
A drying oil is an oil that hardens to a tough, solid film after a period of exposure to air, at room temperature. The oil hardens through a chemical reaction in which the components crosslink (and hence polymerize ) by the action of oxygen (not through the evaporation of water or other solvents ).
