Šřikovací laky na ochranu proti objemu vzduchu a dokončovacích prostředků G141, G142, G144T, G145

Application:
- winding protection,
- electro technical devices
- dry transformers.

Main characteristics:
- coloured lacquer, they have excellent protection preferences. 
      -for class B-G 141,
      - for class F- G 142 - G 145,
- those lacquers have advantage, that they dry in air
- soft drying at 80°C make fast polymerisation.
- lacquer G 144 T is often used as end lacquer in dry transformers,
- those lacquers exists in tropical execution as: G 141 T - G 142 T - G 144 T - G 145 T.

Impregnation:
By brush, immersion or pistol after giving 5-10%  diluent. .

Polymerisation (see table):
Possibility to dry in temperature 80 -100°C,a.
In case putting several layers it is obligatory do dry previous layer first. If we want to obtain good resistance for diluents, salt fog, or chemicals it is we must dry it for 2 hours in temperature 130°C.

Storage conditions:
Six months in original and closed package, hidden from the sun or any heat source.

Packing:
Containers 1, 5, 30 l or spray.

Hygiene and protection:
Lacquer G 142 consists ksylen.
