Product Name: HM-626 Surface Sizing Starch
Product introduction:
The product adopts the latest synthetic technology to introduce the compound ester group, which greatly improves the adhesive force between the starch paste and the natural fiber. The surface strength can be improved and the dry linting issue can be minimized after the surface sizing. It’s the best surface sizing for fine paper.

Detailed Introduction

HM-626 Efficient Surface Sizing Starch

Application:

One kind of surface sizing for fine paper such as two-side offset paper, electrostatic copying paper, copper plate paper, NCR paper, etc. It can form an even and smooth starch film on the paper surface which greatly increase the picking speed and improve the printing surface.

Performance and Advantages:

1. The paste has low viscosity at high concentration and is suitable for sizing under high concentration.

2. The paste has excellent thermal viscosity stability and fluidity, less impacted by ambient temperature, which makes the sizing effect more stable.

3. The paste is homogeneous and stable, not easy to retrograde.

4. It can form a continuous starch film that is tough and soft, smooth and transparent to increase paper strength and improve its appearance.

Usage:

Add a certain amount of cold water into the gelatinizing tank, boot the stirrer and next add an appropriate amount of HM-626, control the slurry concentration at 5%-20%. Stir for 5 to 10 minutes to make the slurry evenly, after that, heat up to 95℃ slowly by keeping the heat-up rate at 2℃ to 3℃ per minute. Keep 95℃ for 30 minutes after the starch gelatinizes completely. Finally pump it into the storage pool to prepare the required concentration with water.
