Cotch uses traditional Japanese natural paint: astringent persimmon liquid

Persimmon Liquid

Astringent persimmon liquid: the fruits of our ancestors’ wisdom

Astringent persimmon liquid, known as kakishibu in Japan, is made by fermenting the juice squeezed from unripe astringent persimmons. It has traditionally been used in the country as paint for wood and Japanese paper known as washi, fabric dye or folk medicine. The dark brown colour develops as a result of the oxidation of the main component – persimmon tannin. People in the olden days knew from experience that persimmon tannins have antiseptic, waterproof, insect repellent and antibacterial properties.

The more you use it, the deeper its colour becomes

Currently, synthetic resin paints are mainly used for wood products but Cotch selected astringent persimmon liquid for its human- and environment-friendly characteristic. Being filled with the blessings of nature, the power of fermentation and human ingenuity makes it differ from other paints.
While the major drawback to conventional astringent persimmon liquid is its distinctive odour, Cotch uses an odourless type that has been refined using a special manufacturing method. The more you use the wood product, the deeper its colour becomes through the aging of both the wood itself and of the astringent persimmon liquid.
