5887 has excellent defoaming effect, good foam suppression effect, high safety and cost-effective. It has excellent compatibility and can be added at any stage of the production process. It is difficult to select suitable defoamers in water-based two-component polyurethane, water-based baking paint, water-soluble high-temperature baking paint systems etc, the reason is that: the use of strong defoamer is easy to produce shrinkage holes problem while the use of weak defoamer such as polyether defoamer is insufficient in defoaming, in addition, unsuitable defoamer will be easy to cause heat rashs, dark bubbles and other problems, this product is specially developed for use in these systems and has excellent effects.

APPLICATIONS:
5887 can be used in water-based hydroxy acrylic resin, water-based two-component polyurethane, water-based baking varnish, water-soluble amino baking varnish, etc.
APPLICATION PROCESS:
5887 can be added at any stage of production. The long-term effectiveness of defoamers depends on the system and should be tested in different formulations (experiments at different temperatures are recommended). Recommended dosage: 0.5-3% of the total amount, generally 1~2% of the total amount. The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
PACKAGE: 25KG plastic pail.
SHELF LIFE:
Store in a dry and ventilated place. The storage temperature is kept at 5℃ ~35℃. Shelf life is 12 months from the date of manufacture.
