THE ROLE OF SILICATE FILLERS ON THE FORMATION PROPERTIES OF POWDER COATINGS

The current state of the Ukrainianeconomy causes to resolve a range questions related improvement production and increasein ecological safety products, including paintand-varnishes materials, in combination with ensuring high operational properties coatings based onthem.The formation high-quality paints varnishes long service life without compromising ecology environment when usingthem, is largely determined by composition andphysical mechanical andvarnishes.The main disadvantage using liquid andvarnishes traditional for Ukrainian market rangeis content solvents their up to40%, which inevitably leads emission during application, as well environmental pollution. This problem can be solved byscaling eco-friendly powdercoating.According research results, we have obtained paint-and-varnishes ofhigh corrosion resistance on powder coatingcontaining silicates filler form metakaolin talc.Using mentioned fillers coating contributes decrease peelingwidth 2.13 mm metal width 1.38mm after testing salt spray chamber thecondensation 5 % sodium chloride watersolution places into atmospheric corrosivity categories С3 С4 accordingto ІSO 12944-2:2017, creates conditions forusing these compositions context excessive corrosivity.
