The hazards of leveling agent bubbles

Leveling agent is a commonly used coating additive. It is also one of the important varieties in the paint industry. Leveling agents can form a smooth, even, and even film during the drying and film-forming process. It can effectively reduce the surface tension of the plating solution, improve the leveling and uniformity of the plating solution. However, as leveling agents are formulated with active agents, the production of leveling agents will generate a large number of bubbles, affecting product quality, endangering production equipment, and even affecting the use of the coating industry. A good defoamer is particularly important.

Reasons for foaming of leveling agents:


1. Since the flow leveling agent is made of active agent, a lot of foam is produced.


2. Excessive surfactants can cause foaming.


The hazards of foaming with leveling agents:


1. When foam is mixed with other surfactants, foam is produced, which leads to volume expansion and reduces the utilization rate of blending equipment.


2. The foam lasts for a long time, which is easy to cause problems such as poor fluidity, surface defects, uneven surface, film forming process cracking, etc.


3. Resulting in a decrease in product appearance and performance.


4. Damaged to production equipment.

 

Overview of leveling agents and defoamers:


It is an organic polyether ester, mineral oil, and alcohol compound refined through a process. Does not produce surface effects and film-forming properties, but has an impact on water-based coating systems. It has the characteristics of self emulsification, easy dispersion, strong versatility, good defoaming and long-term anti foam. In the process of coating production, packaging and application, foam control is compatible with various systems, with long service life and wide pH range.


Application scenarios:


1. Especially suitable for water-based coating systems;


2. It can prevent microbubbles and large bubbles;


3. High defoaming efficiency;


4. High compatibility;


5. Suitable for varnish and paint;


6. Can be used in airless spray formulations;
