Water is very important component in many coatings: water-soluble, water-thinnable, water dispersing, water emulsion. History, applications and some problems are consideration in this article. 

The combustion mechanism of lithium-ion batteries (LIB) has been studied. Research on the development of fire-intumescent coatings to protect LIB from fire is reviewed. Еstablished that the most effective means of fighting fire in LIA is the combination of fireproofing agents with non-flammable ballistic fabrics has been. revealed that to create an ORP to protect LIBs, paint and varnish compositions based on intercalated graphite and vinyl alkyds should be used has been. 

The article argues that silver, as a biocide, cannot be used to protect water-based coatings from biological damage, because being in nature, their waste will disrupt the microbiological balance in natural ecosystems. More environmentally friendly biocides have been proposed to protect water-based paints from bio-contamination. 

The activity of zirconyl and dizirconyl carboxylates as dryers in combination with cobalt and manganese in the most common types of alkyd binders – fatty alkyd varnish, alkyd-urethane and alkydstyrene lacquers, was studied.

In this purpose, 2-ethylhexanoates of zirconyl and dizirconyl were put in various ratios with primary dryers (2-ethylhexanoates of cobalt and manganese) into varnishes and applied to a glass substrate. Then the drying time and the rate of hardness gain of the obtained films were measured.

It was found out that for all types of binders, the activity of zirconium dryer depends only on the amount of metal introduced into the varnish and, in the case of using 2-ethylhexanoates of zirconyl and dizirconyl, does not depend on the type of zirconium compound used. The optimal molar ratios of cobalt with zirconium (1:2) and manganese with zirconium (1:1) have also been identified, which allow to obtain the maximum drying rate and a set of hardness of alkyd binders. 

The article discusses the possibilities of using innovative methods for the design and development of powder paint production lines. The problem of choosing software for searching and identifying problem areas of the line for subsequent effective solution of the found shortcomings has been solved. The features of the production of epoxy powder paints and the development of production lines for the paint and varnish industry were studied. Using the AutoCAD software environment, a project was created to modify and reengineer a section of the production line for producing and applying powder paints.
