HQ-N9133 Neutral Sizing Agent

HQ-N9133 Neutral Sizing Agent is an internally-applied sizing agent synthesized through a specialized process with self-retaining properties. Its standout features include significantly simplifying the sizing process while enhancing wet fiber bonding strength and improving the dry strength of finished paper. Through years of iterative improvements, its curing time has also been substantially reduced. Suitable for diverse production environments, it delivers effective application results with low costs, rapid curing, and high paper strength—making it an excellent choice for internal sizing agents.
Scope of Application:
Woodfree writing paper, lightweight paper, electrosensitive carbonless paper, medium-strength corrugated paper, cup base paper, etc.
