Hefei white latex adhesive is a type of adhesive. White latex adhesive can often be seen when decorating a house. However, the bonding effect of white latex adhesive purchased from different merchants will be different because each manufacturer adds different items during production, and white latex adhesive cannot be used on all items.

1. Because white latex adhesive contains evaporative solvents, it cannot be placed near open flames, as it will simply burn when exposed to fire.
2. The decoration site where white latex adhesive is applied needs to maintain indoor ventilation.
3. If the viscosity of white latex adhesive is too high, it can be diluted with ethyl acetate or petroleum for better use effect.
4. During the production process, it should be kept away from free formaldehyde ≤0.5g/kg, benzene ≤5g/kg, toluene + xylene ≤200g/kg, total volatile organic compounds 750g/L, etc.

White latex adhesive is one of the widely used water-soluble adhesives in the building materials industry. It can cure quickly at room temperature, has a fast curing time, and high bonding strength. It is widely used in various professions. However, white latex adhesive produced by some small manufacturers is of substandard quality, and Hefei white latex adhesive often develops black spots. People often ask what to do when black spots appear on white latex adhesive.

1. The white latex adhesive may have been固定 in one direction for too long, and the panel absorbed the water from the white latex adhesive, causing the panel to rot and develop black spots. You can first find an unused panel, then pour two cups of tap water. After absorbing the water, see if the panel turns black. If there are black spots, it indicates a problem with the panel, and vice versa.
Treatment method: When applying white latex adhesive, reduce the amount used and apply it evenly.

2. The amount of white latex adhesive applied during bonding may be uneven.
Treatment method: Pay attention to the amount of adhesive used. High-quality white latex adhesive generally has low water content, short setting time, and fewer black spots.

3. The base layer of the panel may be of poor quality and too thin.
Treatment method: When selecting panels, it is recommended to look at the cross section and ensure it does not change color.

The above is the introduction to what to do when black spots appear on white latex adhesive. It is recommended to find out the cause of the black spots on white latex adhesive before处理 the problem, so that targeted treatment can be carried out.
