Product Description

Polydadmac is the basic cationic polymer without formaldehyde.

POLYDADMAC is the basic organic coagulant for drinking water treatment and waste water treatment.

PDADMAC (Diallyl dimethyl Ammonium Chloride) is synthesized from allyl chloride and dimethylamine.
In common with other monomers containing allyl groups, DADMAC forms a relatively
stable allyl radical during vinyl polymerization. It limits, the molecular weight of the polymer.

Industrial polymers produced this way present the following characteristics:
1,Molecular weight from 10,000 to 3,000,000
2,Liquid form, active content from 20 to 50 %
3,Cationic site on the secondary chain
4,Viscosity, at 40 %, from 1,000 to 22,000 centipoises
5,Chlorine stability
6,Compatibility with mineral coagulants
7,Long shelf life
8,Usable with or without preliminary dilution

Applications:

• For water treatment, suggested to use it mixed compatible with Poly Aluminium Chloride for water treatment of turbid river and tap water etc.
• When used alone, it should be diluted to the concentration of  0.5%-0.05%( based on solid content).
• The dosage is based on the turbidity and the concentration of the different source water. The most economical dosage is based on the trial. The dosing spot and the mixing velocity should be carefully decided to guarantee that the chemical can be mixed evenly with the other chemicals in the water and the flocs can not be broken.

Frequently Asked Questions
Q1: May I get one free fixing agent sample before placing order?

Re: Yes, Sample are available. For small samples is free and you just need to bear the freight; 


Q2: Which payment is available for your company?
Re: T/T, L/C or D/P. You can choose the one which is convenient for you. 

Q3: How and when can I get my goods after payment?
Re: For small quantity products, they will be delivered to you by international courier within 2 days(DHL, FedEx, TNT etc.) 

For large quantity products, shipping by sea is worthwhile.It will cost days to weeks to come to your destination port, which depends on 

where the port is.

Q4: Is there any possible to use my appointed label or package?
Re: Yes. If needed, we'd like to use label or package according to your requirement. 

Q5: How can you guarantee the goods you offer is qualified? 
Re: We always believe honesty and responsibility are basis of one company, so whatever products we provide 

for you all are qualified. We will have goods tested and provide COA before delivery for sure.
