METHOD OF MAKING WATER-REPELLENT ELEMENT AND USE THEREOF Russian patent published in 2020 - IPC B27N5/00 

FIELD: chemistry.

SUBSTANCE: group of inventions is intended for making a water-repellent coating element from a material on a biological basis, and particularly from organic substances obtained from sustainably renewable resources. Method of making the water-repellent element (H, H', H", 8) of the coating comprises the following steps: a) preparing mixture (M) from water and organic substance obtained from sustainably renewable resources, b) moulding mixture (M) prepared at step a) to obtain moulded element (E), c) drying and compacting moulded element (E) obtained at step b) to obtain a dried and compacted element (S), d) the impregnation of the dried and compacted element (S) obtained at step c) with a binder consisting of organic substances obtained from sustainably renewable resources. Produced water-repellent element (H, H', H", 8) coating contains more than 90 % of organic substance obtained from sustainably renewable resources.

EFFECT: use of group of inventions improves quality of finished product.
