Cationic Rosin Dispersion

Overview :
LGS-P-CSS20 product boasts excellent film-forming ability. It can form a waterresistant layer on the surface of paper and cure rapidly, thus demonstrating agreat sizing effect. Besides, it has the benefits of small usage amount, lowcost, and it is easy to use, making it an ideal and wide application to writingpaper, packaging paper, wood-free paper, copying paper, coated art paper,high-strength corrugated paper, Kraftliner board and etc.

The product may replace partor all of internal sizing agent, hence lowering the cost of sizing. Itdemonstrates a great sizing effect after surface sizing. Since the sizing is maintainedon the surface of paper, the paper is thus endowed with excellent waterresistant property. The application of this product greatly improves thesurface strength and printability of paper, ensuring high fidelity, good gloss,dimensional beauty and significantly avoids picking, linting and pasting platein printing. It can be widely used in different surface sizing equipment. Whenused in conjunction with starch, excellent surface strength, stiffness andwater resistance can be ensured. The product also boasts great mechanicalstability and produces little foam, hence no antifoam agent is needed.
