1.Product introduction

This product is copolymerized from various monomers and polymer materials, which can effectively combine with starch, endowing the starch coating with good crosslinking strength and film-forming hydrophobic properties. It features low addition amount, low cost, excellent water resistance, and convenient use, and is widely applicable to high-strength corrugated paper, boxboard paper, white board paper, cardboard, and other papers.

2.Main technical indicators

Appearance: light brown to dark brown liquid   Solid content: 30%±1%

PH value: 2-5                       Viscosity: <50 mPa·s (at 25℃)

Ionic type: Cationic                   Solubility: Easily soluble in water

3.Performance characteristics

1) Significantly improve the high water resistance and ring crush strength of corrugated paper, containerboard, and other paper types;

2) It can completely replace the use of internal sizing agents, with no curing period and low susceptibility to moisture regain;

3) It can be used in combination with raw starch to reduce sizing costs;

4) It exhibits excellent mechanical stability and generates minimal bubbles during operation.

4.Usage method

1) Recommended dosage: 2-4kg per ton of paper.

2) When using, after the pasted starch solution has been cooled to below 70℃, the sizing agent can be continuously added into the pipeline before the sizing pump using a metering pump to mix with the starch solution. For high-speed paper machines, a static mixer can be added after the sizing pump to facilitate mixing.  

5.Precautions

1) Avoid mixing with starch solution too early or for too long.

2) A drying cylinder temperature of ≥105℃ after sizing is more conducive to the sizing effect.

6.Packaging storage

Packaging: 1000kg plastic drums or transportation via tank trucks and liquid bags are both acceptable.

Storage: Store in a cool place (0-30℃), avoiding freezing and exposure to direct sunlight.

Storage period: 6 months.
