Title:
COATINGS WITH THE USE OF NATURAL MATERIALS
Document Type and Number:
WIPO Patent Application WO/2000/077106
Kind Code:
A1
Abstract:
Coatings with the use of natural materials such as a paint, which contains glue as an organic matter and is to be applied onto substrates such as lumbers, an undercoating, an adhesive, etc. aiming at minimize the generation of environmental contaminants by using organic matters made of natural materials and improving the miscibility of glue with other components to thereby facilitate handling. These coatings comprise pyroligneous acid solution the acetic acid component of which acts on glue so that the glue is maintained in a liquid state even at ordinary temperature. For example, a coating serving as a paint comprises from 60 to 80% by weight of liquid persimmon astringency, from 10 to 15% by weight of glue and from 5 to 15% by weight of a purified pyroligneous acid solution (pH 3 to 4). Owing to this composition, the coating can be uniformly mixed with other compositions, thereby solving troubles in handling due to viscosity. Moreover, these coatings comprise organic matters (i.e., glue and pyroligneous acid) made of natural materials and contribute to the relief of environmental pollution (for example, air pollution and soil pollution) when employed and discarded.
