METHOD AND DEVICE FOR CONTROLLING THICKNESS OF COATING LAYER WHEN APPLIED THROUGH CENTRIFUGATION Russian patent published in 2010 - IPC B05D1/00 G11B7/26 

FIELD: chemistry.

SUBSTANCE: invention discloses a method and a device for distributing viscous liquid over the surface of a substrate with high uniformity in a defined region, as well as a method of preparing a substrate. The method of distributing a viscous liquid involves the following steps: the substrate is placed on an essentially horizontal support and viscous liquid which is solidified with UV radiation is applied onto the surface of the said substrate. The substrate is also rotated for radial distribution of the liquid outside. The liquid is thermally conditioned on the surface in order to have a local effect on its viscosity in a special way. The liquid is then exposed to UV radiation at a first intensity for partial solidification, after which excess liquid is removed from the disc through centrifugation and the liquid is then exposed to UV radiation at second intensity for solidification.

EFFECT: said method enables to control viscosity of the liquid which is distributed during centrifugation; the invention also enables uniform distribution of the said liquid.
