BERSIZE 6103

BERSIZE 6103 is a highly effective surface size designed for all types of paper and board surfaces. While BERSIZE 6103 provides good sizing values, it also lubricates so that starch does not stick or pick. BERSIZE 6103 has an anionic charge that makes it compatible with most papermaking surface treatment additives. It can be metered directly to the size press or calender stack with conventional positive displacement pumps and flowmeters.

Properties Suppliers
BERSIZE 6125

BERSIZE 6125 is a very unique surface size for paper and paperboard. It may be used alone or in combination with other surface treatments to give a good printing surface to fine papers. Used by itself, BERSIZE 6125 provides an excellent “ducks-back” effect. Its higher alkalinity provides improved compatibility for most applications.

Properties Suppliers
BERSIZE 6385

BERSIZE 6385 is a very unique surface size for paper and paperboard. BERSIZE 6385 may be used alone or in combination with other surface treatments to give a good printing surface to fine papers. Its higher alkalinity provides improved compatibility for most applications. BERSIZE 6385 is an aqueous emulsion which can be destroyed by freezing.
