Lacquer
Lacquer
Lacquer (/ˈlækər/; from the French word lacre, a type of sealing wax) is a type of hard and potentially shiny finish applied to materials such as wood or metal. The finish can be of any sheen level from ultra matte to high gloss, and it can be further polished as required. It is also used for lacquer paint, which typically denotes a paint that dries to a more than usually hard and smooth surface.
Etymology
The term lacquer originates from the Sanskrit word lākshā (लाक्षा), which represents the number 100,000. It was used for both the lac insect (because of their enormous number) and the scarlet resinous secretion it produces that was used as wood finish in ancient India and neighbouring areas.
Types of Lacquer
There are several types of lacquer, including Nitrocellulose lacquer, Acrylic lacquer, Water-based lacquer, and Urushiol-based lacquer.
Nitrocellulose lacquer
Nitrocellulose lacquer is made by dissolving nitrocellulose, a highly flammable compound, in a mixture of solvents. This type of lacquer dries quickly and can be polished to a high gloss.
Acrylic lacquer
Acrylic lacquer is a type of lacquer that uses acrylic polymer resins. It is more durable and less likely to yellow than nitrocellulose lacquer.
Water-based lacquer
Water-based lacquer is a type of lacquer that uses water as a solvent. It is less toxic and has less odour than other types of lacquer.
Urushiol-based lacquer
Urushiol-based lacquer is a type of lacquer that uses the sap of the lacquer tree. It is a traditional Japanese lacquer and is known for its high quality and durability.
