Antistatic Agent SN

Antistatic Agent SN (stearyldimethylbenzylammonium chloride, SDBAC) is a cationic quaternary ammonium antistatic supplied as a reddish-brown viscous liquid (1% pH 6.0-8.0, quaternary ammonium content 48+/-2%). It eliminates static on polymers and textiles, is water- and solvent-soluble, heat-resistant below 180 degC, and gives a long-lasting effect for plastics, rubber and coating processing.

Frequently asked questions

What is the temperature limit for Antistatic Agent SN?

SN is a cationic quaternary ammonium salt (stearyldimethylbenzylammonium chloride, SDBAC), published as a reddish-brown viscous liquid with quaternary ammonium content 48±2% and pH 6.0–8.0 at 1% (20°C). The key process limit is heat: it is stable below 180°C and decomposes above that, so keep it out of any step that runs hotter — that is the number to design your compounding or drying temperature around.

Which polymers and solvents does SN work with?

It is used for antistatic treatment on PVC, PP and PE, plus rubber, textiles, coatings and packaging film. On solubility it dissolves in water, ethanol, toluene, acetone, DMF, dioxane and ethylene glycol monobutyl ether at room temperature, and in carbon tetrachloride, dichloroethane and toluene at 50°C — so it can be dosed into aqueous or solvent-based systems depending on your line. Check compatibility with your specific resin and solvent blend in a small trial.

What backs the SN specification?

Identity is double-verified: CAS 86443-82-5 matches the original product page and the client manual. The spec block — cationic type, reddish-brown viscous liquid, pH 6.0–8.0, quaternary 48±2%, the solubility and the below-180°C heat limit — is transcribed from those sources. We recommend a lot-specific COA for incoming QC.

How do I trial SN and handle the viscous liquid?

Free 500–1000 g sample (freight to buyer, deductible from bulk). As a reddish-brown viscous liquid it may need warming or dilution to dose evenly — confirm pumping and mixing compatibility with your equipment, and keep process temperature under 180°C. MOQ, price and lead time on request.
