The Defoaming Agent Produced in China has Similar Performance to FOAM BAN®1880

Product Name: Defoamer

Item No.: SilibaseDFX-054N

China's defoamer technology continues to improve, with significant cost-effectiveness advantages, making it an ideal alternative to FOAM BAN® 1880.SilibaseDFX-054N silicone defoamer is a nearly 100% active dilutable defoaming concentrate, which can be used in small amounts to achieve the required durability of traditional defoamers. It is used in conventional surfactant and polymer foaming systems; It is recommended to use in the following industries: sewage treatment, industrial cleaning, adhesives, etc.

Silibase Silicone Produces Advanced Defoamer with Comparable Quality to FOAM BAN® 1880, both of which can quickly eliminate foam and inhibit foam regeneration for a long time.

Composed of polyether-modified polysiloxane, polyether polyol, and silicone actives

Appearance: Milky white viscous liquid at normal temperature, no sediment, no visible mechanical impurities

Viscosity (25℃/mPa·s): 1000-2000

Defoaming rate(ml/s): >20

Inhibition rate(ml/s) :>2

Note：The information above is for reference and shall not be deemed as a technical indicator.

The anti-foaming efficiency of Chinese defoamer is comparable to that of FOAM BAN®1880 and is suitable for water-based systems and a variety of industrial applications.

- Semi-synthetic metalworking fluids (high and low oil content)

- Synthetic metalworking fluids

- Soluble oil metal working fluids

- Anti-freeze coolants

- High water content and water glycol hydraulic fluids

- Industrial cleaners

The properties and performance of a defoamer are greatly dependent upon the specific formulation in which it is utilized and, consequently, should always be tested (possibly at different treatment levels, temperatures, and/or time intervals) to verify performance prior to use. A starting dosage level from 0.05% to 0.20%, based on the weight of the formulation, is recommended.

Attachment 1:

1.Test Conditions

Test temperature: 25℃

Test medium type: standard foaming liquid (GB/T 26527-2011)

Test medium addition: 150ml

Defoamer use method: Direct addition of antifoam stock solution

Defoamer added amount: 0.2g

2.Testing method:

Take 100g of standard foaming liquid in 250ml sample bottle, heat it to the test temperature in water bath, then add the specified amount of defoamer; place the sample bottle on the vertical oscillator; set the parameters: frequency is 450rpm/min, amplitude is 30mm; respectively oscillate the plastic bottle for different time; After each oscillation stop, record the time t' of' the foam disappeared to see most of the liquid surface, and the foam volume after the shaking of the blank standard solution was recorded as V.

3.Elimination and suppression rate calculation method

The ratio of the foam volume V formed by vertically oscillating the blank foaming liquid to the

defoaming time t' of each oscillation after the addition of the antifoaming agent. The data of vertical oscillation for 1 min is recorded as the defoaming rate, and the data of vertical oscillation for 5 min is the foam suppression rate.

ŋ=v/t'；

v —Foam volume；

t'—Defoaming time after defoamer addition.
