Product Name: HM-630 Interlaminar Spray Starch
Product introduction:
The product is used for paper or paperboard with multiple fiber layers in the wire section. It is evenly distributed on the joint of different fiber layers to not only increase the interlaminar binding force but also enhance the ring crush strength and stiffness.

Detailed Introduction

HM-630 Interlaminar Spray Starch

Product Overview：

HM-630 Interlayer Spray Starch is specifically designed for multi-layer paper and paperboard. Applied by spraying at the junction of different fiber layers in the wire section, it effectively enhances interlayer bonding, ring crush strength, and stiffness.

Key Features and Benefits：

1. Easy Application: Requires no cooking, forms uniform suspension in cold water

2. High Retention: Excellent first-pass retention with no negative impact on recycled paper production
3. Optimal Gelatinization: Suitable gelatinization temperature ensures complete cooking during drying
4. Superior Adhesion: Excellent bonding performance with fibers
5. Uniform Granulation: Ensures good atomization and even distribution without nozzle clogging.

Preparation Method：
1. Add room temperature water (≤40°C) to dissolving tank
2. Start agitator and add HM-630 to prepare 2-5% suspension
3. Transfer to storage tank after thorough mixing
