keyword
Dimethylsilicone oil, Polydimethylsiloxane, concrete defoaming agent, antifoaming agents
Alias: methylsilicone oil, polysiloxane, dimethylsiloxane
CAS: 63148-62-9
Main characteristics and uses
Dimethyl silicone oil is tasteless and non-toxic, has physiological inert, good chemical stability, electric edge and weather resistance, wide viscosity range, low setting point, high flash point, good hydrophobic performance, and has a high shear resistance, can be used for a long time in 50-180C temperature.
Performance advantage
Decobbing is fast and lasting time
Disdispersion and compatibility are good, use does not produce residue in the foaming system
General defofoaming agent products can be applied to multi-industry bubble problems
Good heat resistance, which is little affected by the temperature of the foaming system
The chemical properties are stable
