Alkyd An alkyd is a polyester modified by the addition of fatty acids and other components. They are derived from polyols and a dicarboxylic acid or carboxylic acid anhydride. The term alkyd is a modification of the original name alcid, reflecting the fact that they are derived from alc ohol and organic ac id s. The inclusion of the fatty acid confers a tendency to form flexible coating. Alkyds are used in paints and in moulds for casting.

Get the Federal Income Tax Rates for 2015 Income tax rates begin at 10% and gradually increase to 15%, then 25%, then 28%, then 33%, then 35%, and finally reaching a top rate of 39.6%. Each tax rate applies to a specific range of income. This range is called a tax bracket. Where each tax bracket begins and ends varies depending on a person's filing status.

The 7 Myths of Polyurethane Oil-based polyurethane is simply a type of varnish. It’s common alkyd varnish made with some polyurethane resin added. Alkyd is the resin used in almost all varnishes and oil-based paints. The polyurethane resin adds scratch, heat, solvent and water resistance to the alkyd varnish. Pure polyurethanes (with no alkyd resin) are always two-part products.

alkyne (āl'kīn') Any of a group of unsaturated hydrocarbons that havee carbon atoms in chains linked by one or more triple bonds and that have the general formula CnH2n-2. Alkynes can be solid, liquid, or gaseous and include acetylene. ◇ The group of alkynes as a whole is called the alkyne series or the acetylene series. The first five members of the alkyne series are acetylene (or ethyne), propyne, butyne, pentyne, and hexyne.

Advantages of the Alkyd Medium Fortunately there is an alternative which few artists have been exposed to. Imagine a medium that offered all the advantages of oil — versatility and buttery feel — but a quick drying form, and with none of the disadvantages of acrylics. Alkyds dry much faster than oils, but slower than acrylics. The paint remains workable (wet) for many hours, depending on how thickly it is applied, the temperature of the environment, and whether or not any additional alkyd-based painting medium is added as you work.

Aldehyde An aldehyde /ˈældɪhaɪd/ or alkanal is an organic compound containing a functional group with the structure −CHO, consisting of a carbonyl center with the carbon atom also bonded to hydrogen and to an R group, which is any generic alkyl or side chain. The group—without R—is the aldehyde group, also known as the formyl group. Aldehydes are common in organic chemistry. Many fragrances are aldehydes.
