  • Why is cationic Pam used in oxidized starch solution?
  • The addition of cationic PAM to the oxidized starch solution helps keep starch molecules on the paper surface rather than penetrating into the paper structure. Surface sizing is employed to increase the wetting resistance against liquids and to improve the strength and surface properties of paper.
  • Can cationic Pam be used as a surface sizing additive?
  • This study focused on the use of cationic PAM as a surface sizing additive for improving the surface sizing properties of paper. The effect of various cationic PAMs on starch holdout and bending stiffness was investigated.
  • Can cationic Pam additives improve bending stiffness of paper?
  • The penetration of surface sizing agents into paper and the enthalpy changes accompanying the mixing of cationic PAMs with oxidized starch were investigated to evaluate the hypothesis that the bending stiffness of paper can be enhanced by the addition of cationic PAM additives to the surface sizing solution.
  • Does cationic Pam affect optical properties of paper?
  • The penetration of starch affects the optical properties of paper (Lee et al. 2002; Hubbe and Gill 2016). To investigate the effect of cationic PAM on optical properties of paper, the brightness and opacity were determined after surface sizing using cationic PAMs and SA as additives (Fig. 2). The brightness of unsized base paper was 83.1%.
