Technology
YEST SCHUTTERS ARE POWDER LACQUERED.
Powder lacquering:
It is the most effective and also one of the most modern methods of metal coating.
Unlike liquid paints, powder lacquers yield smooth coatings, without breaks, sagging of bubbles.
They are used for protective painting (protection of elements from corrosion) as well as decorative painting.
They are characterised by very good mechanical properties and high resistance to chemical factors.
Powder lacquering technology:
Powder lacquering technology comprises applying electrostatically a powder layer onto an element and polymerising it in high temperature.
It is very important that the particular element is that the element is previously subjected to a surface preparation treatment.
Surface preparation in the case of aluminium: degreasing, etching, chromating.
Once the technological processes are finished, elements are subjected to mechanical studies, which include, e.g. coating thickness, shine, adhesion, ability to undergo moulding, bending, impact resistance,
coating hardness analysis using Buchholtz method, accelerated corrosion test.
