N-Methylol Acrylamide / N- hydroxymethyl acrylamide
CAS: 924-42-5 Chemical Formula:C4H7NO2
Properties
White crystals, soluble in water and hydrophilic solvents, soluble in fatty acid lipids, almost insoluble in hydrocarbons, halogenated hydrocarbons and other hydrophobic solvents. This product is a self-inbred active monomer, containing a double health conjugated with hydroxyl group, which is prone to condensation reaction in neutral or alkaline media. It is unstable in moist air or water, easy to polymerize, and will quickly polymerize into insoluble resin when heated in the presence of acid in aqueous solution. If copolymerized with acrylate monomers, hydroxymethyl is introduced and can be crosslinked by heating alone. High quality crosslinked monomer for aqueous emulsion polymerization. The initial reaction was mild and the emulsion system was stable. Good storage stability, no need for low temperature storage.

Application
It is mainly used as a cross-linking agent for water-based adhesive, water-based latex.
Widely used in the synthesis of emulsion adhesives and self-crosslinking emulsion polymers. And is also used for fiber modification, resin processing, adhesive and treatment agent for paper, leather, and metal surfaces, and can also be used as a soil amendment. Organic monomers can be used to prepare a variety of copolymers.
Packaging and storage
25kg/bag, 3-in-1 composite bag with PE liner.
ISO/IBC TANK, 200L plastic drum.
Stored in dry, cool and ventilated warehouse to prevent moisture absorption and self-fusion deterioration.
The shelf life is one year from the date of production, if more than one year, re-inspected,and it can still be used if the inspection is qualified.
