Use & Application
DMAPMA is a cationic water-soluble acrylamide monomer. It is widely used for synthesis of cationic polyacrylamide flocculants for wastewater treatment. It also serves as functional monomer for thickeners, cosmetic polymer, papermaking retention aid, oil field chemicals, UV curable coatings and adhesive modifiers. It can introduce tertiary amine functional groups to polymer chains, offering excellent adsorption and cationic charge performance.
Packing
200kg HDPE plastic drum; IBC tank available on request. Custom packing can be arranged.
Delivery & Storage
Store in cool, dry and ventilated warehouse, recommended storage temperature below 25℃. Keep away from sunlight, heat source, oxidizing agents and radical initiators. Keep drums tightly sealed. Avoid long-time exposure to air and light to prevent polymerization. Shelf life 6 months under proper storage. Handle carefully during transportation to avoid leakage.
