“Model C” Roller Coaters Only
Union Roller Coaters are most versatile in that additions or modifications
can be made to accommodate almost any type of coating problem. Many
coaters have been designed to contain deburring rolls, brush rolls, squeegee
rolls, heated or chilled rolls in addition to coating rolls. Coating rolls can be
chrome plated steel or covered with a number of different coverings including
(but not limited to): Neoprene, Mechanical Neoprene, EPDM, Nitrile, Silicone,
Gelatin, Thiokol, Buna N, Aluminum, etc.
Rolls can be spiral or longitudinally corrugated, depending on the type and
amount of coating material used.
In most cases a smooth ground roll will apply the desired amount of coating
material to the substrate being run.
