Defoamer for Polyvinyl Alcohol

Description 
This product is a kind of high efficient defoamer which made from mineral oil and polyether ester by special technology, it can quickly remove all big and tiny foams that caused by the leather oil, leather coating, acrylic emulsion, aqueous polyurethane emulsion, leather edge oil and the polymers such as styrene-acrylic, ethylene propylene, pure acrylic, casein, polyvinyl alcohol, etc.  
It also can be used in the latex coating adhesives such as vinyl acetate(VAC) and carboxylated styrene-butadiene to control foams problem.
And with the advantages of excellent foams control performance, good leveling property and small dosage, it will not affect the product effect even if overcommitting.  


Characteristic
1. Fast defoaming ability, lasting foam suppressing effect, small dosage, not any effect on the basic property of the foaming system.
2. Good heat resistance, good chemical stability, non-corrosive, non-toxic, non-flammable, non-explosive, no adverse side effects.
3. Comparable with the top quality product on market, while the price is much more affordable.
