Product Description

Reasons why water-based paint foams:
1. Stirring during the production process causes air to enter, thereby forming foam that is difficult to remove.
2. The construction temperature is too low and the viscosity is too high.
3. The foam produced by dragging the paint back and forth is not eliminated in time, the diameter of the spray gun is too small or the pressure is too high, the coating is not clean or dry enough, and the rosin contained in the wood itself causes the coating to bubble.

 

Product Description:

RK-707 is mainly made of mineral oil with a large expansion coefficient and hydrophobic particles as defoaming active substances, assisted by defoaming synergistic substances. Mineral oil increases the expansion velocity of defoaming particles, and hydrophobic particles reduce the entry energy barrier of defoaming particles. The interaction between the two provides excellent defoaming performance. At the same time, mineral oil has a good affinity with organic matter, so it will not cause surface defects. It is mainly used in the emulsion and latex of water-based coatings and the adhesive made by the emulsion, latex, and waterborne building coatings. The effect is more obvious in the system with higher viscosity. It can also be used in leather edge oil.

Product property:
High efficiency in adhesive and coating systems
Suitable for waterborne formulation
Good performances in leather edge oil system

Main physical and chemical properties:

Appearance	Light yellow, opaque liquid
Viscosity(25°C)	1500~8000mPa·s
Active content	100%
pH value	5.5~7.0

Application Process:
Defoamer consists of hydrophobic liquids and hydrophobic particles. It is recommended that the user fully stir before using, even if the surface is not stratified; long-term storage may be slightly stratified, evenly mixed, and used without affecting the effect.
The additive amount is 0.2-0.6% of the coating weight, added 1.0-1.5% at pulping process, added 1.0-1.5% again at paint correction. The optimum addition should be depended on specific situation. Do not dilute. If diluted with water, the antifoaming performance will be destroyed.

Key Applications:
 

Styrene acrylic emulsion, silicone acrylic emulsion, acrylic emulsion, etc coating system

Waterborne latex 

Water-based adhesives and latex paints

Thick slurry and high-viscosity system

Elastic wool drawing, floor paint, leather edge oil system

Packaging & Storage:

Package	25 kg/50 kg/180 kg plastic pail or 850kg IBC drum
Storage Condition	Room Temperature Storage (5ºC-35ºC). Avoid direct sun light; shelf life is 6 months.
