Seal and Pre-Coat
Transparent and pigmented sub-coats that isolate an acid labile core before the enteric layer goes on.
What this range covers
Seal coats and pre-coats give the core a uniform, sealed surface before the functional layer is applied. That step matters most on enteric systems built over moisture sensitive actives such as the Pantoprazole group.
