Chemical characterization
nonyl phenol poly glycol ether 30 Ethoxylate
CAS number : 9016-45-9

NP 30 is a unique nonionic wetting agent and emulsifier for aqueous systems.

NP 30 has pigment wetting and stabilising properties in the paint industry.


NP 30 is used in polymerization of vinyl acetate together with other vinyl esters, acrylates, vinyl chloride and ethylene, for acrylic and styrene / acrylic dispersions and for butadiene / styrene latex.
The use of NP 30 reduces coagulation and improves electrolyte resistance and freeze/thaw stability.
NP 30 is added either during or after polymerization.
NP 30 is also used in pigment preparations,paints and coatings as dispersing and wetting agent.

Characteristics
Both the chemical and processing characteristics of NP 30 depend largely on the ratio of hydrophobic molecules (nonylphenol) to the hydrophilic – i.e. water solubilizing – polyglycolether chain (number of ethylene oxidemolecules).

Compatibility
Being nonionic, NP 30 is compatible with all other nonionic, anionic or cationic substances.

Electrolytes, for example neutral salts, alkalis and – to a lesser extent – acids, reduce the water solubility of NP 30 and may lead to their salting out, especially at high concentrations and temperatures. Decomposition of the products does not occur. 
For solutions containing high amounts of electrolytes, NP 30 with long polyglycolether chains may be used since, being more hydrophilic, they are not so easily salted out.

Stability
NP 30 has excellent resistance to compounds that cause hard water, to metal salts, including those of heavy metals, acids, alkalis, reductive agents and oxidative agents based on peroxide.
