Coatings & lehr
Hot-end coating
A vapour-phase coating applied to ware at the hot end (typically tin tetrachloride SnCl₄ or monobutyltin trichloride MBTC) — creates a tin-oxide substrate that improves scratch resistance and primes the surface for cold-end coating.

SnCl₄ (tin tetrachloride)
Inorganic precursor for hot-end coating; reacts with hot ware surfaces to form a thin SnO₂ layer.
MBTC (monobutyltin trichloride)
Organotin precursor for hot-end coating; alternative to SnCl₄ with different thermal and emission profiles.
Cold-end coating
A polyethylene wax or oleic-acid-based emulsion applied to ware at the cold end (post-lehr) — reduces scratching and improves conveyor handling.
