Wet strength enhancer for papermaking **What is a wet strength enhancer for papermaking?** Paper has the characteristic of significantly weakening its strength when wet. Wet strength enhancers are chemicals added to paper to compensate for this shortcoming and maintain a certain level of strength even when wet. They are mainly used in the production of paper products that are prone to getting wet, such as toilet paper, kitchen towels, napkins, wet tissues, and food packaging. **Main mechanism of action:** Wet strength enhancers form chemical bonds between paper fibers to prevent the fibers fro

​ Fixing agent & Pitch Control agent In the wet end of the paper manufacturing process, anionic substances are effectively controlled, and the sizing agent and wet/dry strength enhancer used in paper production can effectively exhibit their performance.  Pitch control of old paper and recycled pulp. It is effective in the treatment of waste water and is often used as a coagulant for waste water treatment.  In particular, it helps to improve print ability by adding cationic properties during special coating.

​ Sub-Sensitizer   for Thermal Paper. In brief, theory of color development in Thermal Paper, dereloper and dye which coated on paper are melted by heat, and react on the surface of paper so that color development is occurred. At this time, Sub-sensitizer which coated with developer and dye is melted and get fluidity.  Sub-sensitizer assist to reacted dereloper and dye. Also Sub-sensitizer can be reacted with functional group of dye, it could be assist to color development. In additionally Sub-Sensitize could be used not only improve color development but also improve lubrication. Thus, Sub-Se
