BERSIZE® 6030 is an aqueous solution of a styrene based low molecular weight copolymer which can be used in a variety of surface sizing applicatins to provide water resistance and improved printability.


BERSIZE® 6103 is a synthetic size designed exclusively 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. When applied with starch at the size press or wet calender stack, BERSIZE® 6103 imparts water resistance and coating holdout for improved coated surface characteristics at reduced coat weight. BERSIZE® 6103 with its anionic charge makes it compatible with many papermaking surface treatment additives.
