PAPERMAKING CHEMICALS
Internal Sizing Agents
Internal Sizing Agents
Sizing agents are commonly used to prevent paper from blurring with water or ink, and to provide water resistance to paper / paper board, Also the application of these Sizing Agents can make it possible to control the degree of water-resistance to paper as appropriate according to the kind and the application of paper / paper board.
These agents are applied to a wide variety of paper / paper board (writing paper, copying paper, corrugated board, newspaper, postcard, paper cup, paper bag, and so on).
INTERNAL SIZING AGENT AL, CC series
- This series consist primarily of rosin extracted from pine resin. It is applied to various types of paper, corrugated board, and so on.
