One-component sponge spray adhesive DA-6100A

Product Introduction

1.  This product is a pure water-based sponge spray adhesive. It features good initial tack, strong final adhesion, long open time, and excellent high-temperature and water resistance.

2.  Product and Process Parameters

State: Milky white or light yellow liquid

Viscosity: 1000-1200 mPaS

Solid content: 55 ± 2%

Spraying amount: 30-40/m² Spraying distance: 30cm approximately (Do not use too high air pressure)

Open time: 15-20 minutes

Final adhesion: 2-4 hours to break

Initial setting: After spraying, wait 1-5 minutes for bonding, best adhesion (the longer the open time, the stronger the adhesion)

Heat resistance: 85℃,

Water resistance: Soaked in tap water 10 days without delamination.

Uses: Mattress sponge, automotive interiors, sofas, luggage, sponge and density board, leather, low-tension sponge, etc.

II. Precautions

1, It is recommended to use 1.8-2.0mm nozzle spray gun

2, Double-sided spraying is required

3, Do not spray too much adhesive; less is better. Too much adhesive will result in slow drying and poor initial positioning.

4, If higher heat resistance is required, increase the amount of adhesive sprayed appropriately.

5, It is not recommended to add water to this product, as adding water will affect the initial positioning (slow drying). If water must be added, only deionized water can be used;

6, If spraying is not to be carried out for a long time, it is recommended to clean the spray gun promptly. Rinse with pure water.

7, Clean the gun with deionized water, not tap water or well water;

III. Spraying Method

1, Adjust the air and adhesive output of the spray gun; adjust the sprayed adhesive layer to be thin. Both pieces of sponge need to be sprayed with adhesive. It is recommended to adjust the atomization to the minimum or turn it off.

2, After spraying, wait 2-3 minutes for the best sponge bonding effect. Without applying pressure after bonding, the shape can be reset. Pressure is needed between the sponges.

3, After bonding the sponge, it is recommended to wait 0.5-1 hour before moving. 2 hours before further processing.

4, It is recommended to clean the inside of the spray gun at least twice a week. Due to the excellent water resistance of the product, it can be cleaned by soaking in solvent. Soaking for 1-2 hours is sufficient.

IV. Common Problems and Solutions

1, Problem: No adhesive comes out after spraying for a long time

Solution : Clean the spray gun promptly and regularly clean the inside of the spray gun;

2, Problem: The sponge sticks immediately after spraying, the sponge does not stick, or the adhesion is weak

Reason: Too much or too little adhesive, slow drying due to high humidity or low temperature, oil stains or other foreign matter on the sponge, or damp sponge.

Solution: Adjust the amount of adhesive sprayed.

Extend the open time appropriately according to the weather conditions before bonding the sponge.

Use clean, dry sponge.

3, Problem: The bonded sponge cannot be reshaped

Suggestion: If reshaping is needed, do it before applying pressure.
