Pure MonoButylTin TriChloride (MBTC3) at 99,0% to be sprayed on the bottle just after the forming phase at 550°-450°C.
The high temperature makes all the organic components to evaporate, laying an homogeneous coat of Tin Oxide capable of closing the micro cracks of the glass bottle caused by the rough surface of the mould.
The HEC effects are:
- Enhanced mechanical strength of the bottle
- Closing of pathologicals micro cracks of the glass
- Presence of a grip for the successive cold end coating anchorage
