1. Description: It is the raw material for making thermosetting resin, light curing epoxy resin coating, oil resistant coating and drying coating. Its copolymer emulsion is used for fiber finishing, fabric, leather and paper coating. Also used as wood, metal and other adhesives. 2. Typical recipes Used as crosslinked monomer in acrylic emulsion. The amount of carboxyl-containing acrylic emulsion pressure-sensitive adhesive is L % ~ 2% of the total monomer mass, and the initial adhesion will be greatly reduced if it exceeds 3%. For emulsion adhesives without carboxyl group, the general dosage is not more than 5%. The crosslinking reaction temperature of MMAM alone is high, generally 120 ~ 170�ºC, and the addition of protic catalyst can reduce the crosslinking temperature. Acrylic acid (AA) can both provide hydrogen protons and copolymerize with acrylates, so MMAM should be used as a composite crosslinking agent with AA at a dosage of 3:2. Cross-linking agent HA can replace N- hydroxymethyl acrylamide, and does not contain formaldehyde. 3. Application scope A. Can be used as crosslinking agent, widely used in fiber modified resin, processing dyes, plastic adhesives, soil stabilizers, etc. B. Used for fiber modification, resin processing, adhesives and paper, leather, metal surface treatment agent. Free samples 4. Storage and packaging A. All emulsions/additives are water-based and there is no risk of explosion when transported. B. This product can be packed in 25KG,50KG,200KG,1000KG plastic barrels. C. Store sealed in a cool, dry and ventilated place indoors. Before use, the container should be strictly sealed after each use. D. The product should be well sealed during transportation, moistureproof, alkali strong acid and rain water and other impurities mixed.
