Calender Stack Lubricants

BERCHEM® 4000

(Technical Data)  is a nonionic polyethylene emulsion, primarily designed to impart superior lubricating properties to coating formulations used for paper and paperboard. Applications of BERCHEM® 4000 at the calender stack’s water box prevent sticking and picking. Its wide compatibility with other chemicals makes it adaptable to most formulations where lubricity is required.

BERCHEM® 4040

(Technical Data) is an effective lubricant for calender stack applications, providing excellent anti-picking or anti-sticking properties to paperboard when introduced at the calender stack’s water box. BERCHEM® 4040 also contributes to the sizing of the paperboard.

BERCHEM® 4185

(Technical Data)  is a newly developed coating additive specifically designed to promote clean runnability in calender stacks and provides surface coating holdout. It can eliminate or significantly reduce dusting of all clay coating at the supercalender, and is especially effective in roto-gravure formulations which typically contain lower binder levels than offset formulations. In addition, BERCHEM® 4185 provides excellent anti-picking or anti-sticking properties to paperboard when applied at the calender stack's water box.
