[how to use polyurethane defoaming agent]: recommended dosage: the amount of polyurethane defoaming agent added is 0.1~1℅ of the total quantity, but the most economical dosage should be determined after process testing.
[application occasions of polyurethane defoamer]: used for: leather coatings of styrene-butadiene latex, acrylic emulsion, silicone-acrylic emulsion, styrene-acrylic emulsion, acrylic emulsion, polyurethane emulsion mixture, leather edge oil and water-based polymer glue, thick-build acrylic emulsion, resin production and degassing and defoaming of polymer systems. special defoaming agent for leather coatings, anti-crater type, good leveling, defoaming and foam suppression. applications: leather edge oil, water-based lamination glue, and coating coatings based on matte and medium-gloss acrylic emulsions and water-based polyurethane emulsions.
[storage and transportation packaging]: packaging: this product is packed in 50kg, 120kg, and 200kg plastic barrels. storage: this product is not a dangerous goods, non-toxic, non-flammable, sealed and stored in a cool, ventilated and dry place indoors. containers should be tightly sealed after each use before use is complete. the shelf life is 12 months at around 25℃. transportation: this product must be sealed during transportation to prevent moisture, strong alkali, strong acid, rainwater and other impurities from being mixed in.
[characteristics of polyurethane defoamer]: this product is a defoaming agent made from mineral oil and polyether ester through a special process. it can quickly eliminate styrene-butadiene latex, leather coatings, large and fine bubbles produced by acrylic emulsion, water-based polyurethane emulsion, leather edge oil, styrene acrylic, ethylene propylene, pure acrylic, casein, polyvinyl alcohol and other polymers, also suitable for vinyl acetate, carboxybutyl styrene, etc. the latex-type coating adhesive has the advantages of fast defoaming, long-lasting foam suppression, good leveling, and low dosage. even excessive use will not affect the product effect. 1. it has strong defoaming and foam-suppressing power and a small dosage without affecting 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 its price has obvious advantages.
