Our value is your benefit
Butyltin trichlorite (MBTC) is sprayed with a spray pump before the glass bottle enters the annealing furnace, so that it forms a transparent and tough film on the glass surface at high temperature, which can significantly improve the surface hardness, compressive strength and impact strength of the glass bottle, reduce the damage of wine bottles during the transportation, and increase the light transmittance and surface brightness of the glass bottle surface, making the surface light of the product soft and natural.
MBTC | Appearance | Density | Molecular Weight | Boiling Point | Freezing Point |
MBTC-100 | Clear brown liquid | 1.7kg/l | 282 | @ 760 mm: 190℃ - 200℃ @ 210 mm: 108℃ - 115℃ | -63℃ |
Advantages:
MBTC-100 hot end coating can make tin oxides coating on glass bottle, just like tin tetrachloride or titanium tetrachloride, it has unique and distinct advantages against other coating chemicals:
It is a liquid from -60℃ - 200℃, therefore, it can be easily pumped at any time of the year.
It has a low vapour pressure, so exposure to fums when opening drum is low.
It is difficult to react chemical action, as it is stable in environment humidity, it's usage amount can be efficiently reduced in summer.
