FAQ
Q: What is CAS 5039-78-1? What are its aliases?
A: It is methyl acrylate ethyl trimethyl ammonium chloride (DMC), a quaternary ammonium salt type cationic polymerizable monomer; the market commercial forms are almost all 75-80% aqueous solutions, and there are no pure solid products.
Q: What are the regular quality indicators of Methacrylatoethyl Trimethyl Ammonium Chloride?
A: Mainstream 78% specification COA testing items:
– Active substance content: 78 ± 1%
– Color APHA ≤ 50
– pH: 3.0 – 6.0
– Free acrylic acid MAA ≤ 0.5%
– MEHQ anti-oxidant: 1000 ± 100 ppm (The content of the anti-oxidant is the most concerned indicator by customers, and it can be adjusted as needed)
Q: How is the solubility?
A: It is completely miscible with water; it can be dissolved in polar solvents such as alcohols; it is insoluble in non-polar solvents such as hydrocarbons and esters; it is suitable for aqueous phase polymerization systems.
Q: Sample policy?
A: Support sample orders. After the large quantity order is placed, the sample fee can be refunded.
Companion documents: COA, MSDS, TDS.
Q: How long is the delivery period for large quantities?
A: – Standard 78% stock: After receiving the deposit, 7-12 working days.
– Customized anti-oxidant content / low free acid specification: 12-20 working days.
