Features of glue defoamer

Mar 26, 2021

The oil-based glue defoamer is made of ether, fatty alcohol and multiple active additives through a special process. It is easy to disperse in water-based system, has strong self-emulsification, good defoaming, long-lasting foam suppression, and has special effects on water-soluble polymers and medium- and low-viscosity systems. It is especially suitable for latex-type water such as styrene-acrylic, ethylene-propylene, pure acrylic, vinyl acetate emulsion, and carboxyl butyl styrene. It has the characteristics of good defoaming, good foam suppression, good leveling, low dosage, no bleaching oil, no fish eye holes, and does not affect the appearance and coating performance of the product.

1. It has strong defoaming and anti-foaming power, with a small amount, and does not affect the basic properties of the foaming system.
2. Good heat resistance, chemical stability, non-corrosive, non-toxic, no adverse side effects, non-flammable, non-explosive.
3. Its performance is comparable to imported products, and the price is more obvious.

Note: The values ‚Äč‚Äčlisted in this data sheet only describe the typical properties of this product, and do not represent the specification range.

Application occasions of oil-based glue defoamer]:
Oil-based glue defoamer is used for synthetic latex, Armonia gum, natural latex, natural rubber, synthetic fiber, synthetic resin emulsion, synthetic rubber defoaming and degassing, water-based printing glue and coating glue, water-based high-viscosity glue Defoamer, etc.

How to use oil-based glue defoamer:
Recommended dosage: The oil-based glue defoamer is added at 0.1% to 1% of the total volume, but the most economical dosage should be determined after the process test; it can also be used after evenly mixing with other powdered additives.
Storage: Transportation and Packaging]:
Packing: This product is packed in 50KG, 120KG, 200KG plastic drums.
Storage: This product is not dangerous, non-toxic, non-flammable, sealed and stored indoors in a cool, ventilated and dry place. Before use, the container should be strictly sealed after each use. About 25 C, the shelf life is 12 months.

What are the functions and characteristics of glue defoamers?
Whether the coating is dried and formed into a smooth film is the standard for evaluating the leveling properties of the coating. Smooth and smooth coating means excellent leveling. On the contrary, a leveling agent is needed to improve poor leveling.

This is especially true for water-based paints. In fact, the rapid development of water-based coatings symbolizes people's progress. After all, people in the past only paid attention to development and did not pay attention to health. However, water-based coatings use water as a solvent or medium, and the nature of water causes many defects in water-based coatings.
Poor leveling is one of them. Brush marks, orange peel, roll marks, sagging, shrinkage, pinholes, etc. are all signs of poor paint leveling, which brings many undesirable effects:
1. Decrease in covering efficiency will increase costs
2. Destroy the aesthetics of appearance
3. Weaken the protective effect of the coating on the substrate
4. Not conducive to drying and film formation

There are many factors influencing the leveling of coatings. Surface tension, shear force, viscosity changes, solvents, etc. all affect the paint film to varying degrees, and at the same time affect each other. The leveling agent is added to achieve a good leveling effect by influencing the balance of various factors in different stages. However, different types of leveling agents have different mechanisms of action and different effects. Therefore, when selecting leveling agents, the problems to be solved and the structural categories of additives should be considered comprehensively.
