● What is lacquer?
Lacquer has more than 1,000 years of history. People have used lacquer tree for medicine and lacquer liquid as paint.
The word lacquer can refer to either the lacquer liquid which is used as paint or the technique of varnishing lacquer. Before, lacquer used to be used for painting wooden work, but nowadays it is mainly used for artwork as it is produced in small quantity and expensive. While it is excellent in the hardness of paint film, adhesiveness and gloss, it is hard to make a light color.
Nevertheless, it has more profound feeling than paint or enamel and thus is used for artistic sense.
The reason that this lacquer is shed new light now; of course it can make beautiful colors, but it has many merits in function.
First of all, unlike other paints, it does not use any chemical materials from production to processing. The solvent used for dilution is also environment-friendly because it uses natural vegetable oil, not ordinary thinner. Moreover, the results of the test conducted by Korea Industrial Technology Testing Institute show that the absorption of electronic wave is reduced by 30%~70%, and lacquered-coated products have 99% of anti-bacterial activity, 84% of deodorizing power, and has up to 89.5% of far-infrared radiation emission rate daily.
Besides, lacquer-coated metal and wood have remarkable durability against heat, acid or corrosion. A good example of the effect of lacquer coating is The Tripitaka Koreana, our cultural asset made during the Goryeo Dynasty.
● Anti-bacterial activity against super bacteria
Urushiol, the main ingredient of lacquer, is known to have damp-proofing effect, anti-bacterial activity and insecticidal property. Recently, the results of the examination carried out by FITI Testing Institute show that urushiol has over 99.8% anti-bacterial activity against the bacteria which developed resistance to antibiotic, that is, Super-Bacteria. Thus lacquering can be used in hospitals where super-bacteria can grow easily, and can be used for hospital bed, wheel chair, door and window, table, door handle.
- What is Super-Bacteria?
Unlike ordinary bacteria which can be killed by antibiotic, super bacteria does not be killed by even powerful antibiotic as it develops resistance as a result of frequent usage of antibiotic.
If infected by super bacteria, the effect of antibiotic will decrease and it is difficult to cure the disease.
