Is paintdefoamer really the indispensable core of paint foaming?

Everyone is familiar with the word coating. The traditional Chinese name for “coating” is paint. Coating refers to a type of liquid or solid that is coated on the surface of an object and can form a thin film under certain conditions to provide protection, decoration or other special functions. Materials. Nowadays, a large amount of foam will be produced during the production and construction of coatings. The generation of these foams mainly depends on the construction method of the coating. If there are too many surfactants and the coating contains chemicals that are prone to foaming, the foam will introduce volume expansion. , which reduces the utilization rate of the blending equipment, reduces the quality of the paint, and affects the effect of use. If the foam problem is not solved in time, it will cause production costs for the manufacturer. Therefore, many paint manufacturers will choose to use paint at this time. Defoaming agent to solve the bubble problem.

Why does paint bubble?

1.Small surface tension

2. Presence of surfactants

3. There are gaps in the substrate to be painted

4. High surface viscosity

5. Improper spraying, brushing, roller, etc. operations during the construction process

What are the dangers of paint bubbling?

1. Foam is generated during the mixing and mixing process with other surfactants, causing volume expansion and reducing the utilization rate of the blending equipment.

2. Foam limits the stirring speed, prolongs the blending time, and prevents fillers and dyes from being fully moistened.

3. When foaming, the packaging barrel cannot be filled. The gradual disappearance of foam will cause the weight of the packaging barrel to be uneven, interfering with continuous packaging.

4. The foam lasts for a long time, resulting in poor fluidity, surface defects, unevenness, rupture during film formation, etc. during the construction process.

5. When using paint through spraying, roller coating or screen printing, internal bubbles may occur, which affects product quality.

What is a paint defoamer?

The coating defoaming agent is refined through a special process and has the properties of self-emulsification, easy dispersion, strong versatility, good defoaming, and long foam suppression time. It will not cause surface defects or affect film formation, and has special effects on water-based coating systems.

Controls foam generation during coating production, packaging and application, has good compatibility with a wide range of systems, has long duration and is useful over a wide pH range.

Application scenarios:

1. Especially suitable for water-based coating systems;

2. Can prevent microbubbles and macrobubbles;

3. High deaeration efficiency;

4. High compatibility;

5. Suitable for varnish and paint;

6. Can be used for airless spray formula;

7. Surface coating of high-build paint and synthetic latex;

8. Latex paint for interior and exterior walls; waterproof coating, medium and high PVC latex paint, relief paint, various engineering paints, etc.
