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.

CaH 2 is thus used as a drying agent, i.e. a desiccant. [2] CaH 2 is a saline hydride, meaning that its structure is salt-like. The alkali metals and the alkaline earth metals heavier than beryllium all form saline hydrides. A well-known example is sodium hydride, which crystallizes in the NaCl motif. These species are insoluble in all solvents ...
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.
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'.
Lead soap was also used as an oil drying agent for paints made with drying oil or air drying paints made with alkyd resins. Lead is often used with cobalt driers. Lead free substitutes have been developed to replace this use of lead in paint. A second basic lead carbonate is known with the formula 6Pb(CO 3)·3Pb(OH) 6 ·PbO. [7]
