Improve Toner Adhesion
Bercen has developed two different types of chemistries as additives for improved toner adhesion for either paper coating formulations or the size press: Berbond 8990 and Bersize 6030
Berbond 8990, when added to a paper coating at upwards of 3 parts, can significantly improve the HP Indigo liquid toner adhesion as determined from the RIT tape pull test. For size press formulations, Bercen has recently developed Bersize 6030. Bersize 6030 can improve the toner adhesion of a size press formulation significantly over the competition while also increasing the sizing of the paper sheet. Both of these products have demonstrated the improved HP Indigo toner adhesion at low dosages; 3 parts of Berbond 8990 within a paper coating formulation and 1 pound per ton of Bersize 6030 within a size press formulation. See attached RIT-PAL data for comparisons between Berbond 8990, Bersize 6030, and a competitive product.
