| Structural formula |  |
| Properties | Appearance: colorless to pale yellow transparent liquid Solid content (%): ≥ 99 Viscosity (25 °C): 150 to 250 cp aziridine group content: 6.77 mol / kg Density (20 °C): 1.1 g / ml Freezing point (°C ): -15 ° C Boiling point range: far greater than 200 °C (polymerization) Solubility: water, alcohol, ketone, ester and other solvents are completely dissolved |
| Storage | Stored in a dry, cool, sealed condition, be sure to avoid contact with acids and oxidants; avoid freezing. The storage period of the product is 12-18 months under the original packaging conditions from the date of production; non-flammable, explosive; there is a certain degree of corrosiveness, belonging to the general dangerous goods. |
| Application | Widely used in water-based and some solvent-based inks, coatings, pressure-sensitive adhesives, adhesives, etc., it has significant resistance to washing, scrubbing, chemicals, and adhesion to various substrates. The improvement is; the cross-linking agent belongs to an environmentally-friendly cross-linking agent, and no harmful substances such as formaldehyde are released after cross-linking, and the finished product is non-toxic and tasteless after cross-linking. |
| Usage Dosage is usually 1 to 3% of the solid content of the emulsion. The pH value of the emulsion is preferably 8 to 9.5. It should not be used in an acidic medium. This product mainly reacts with the carboxyl group in the emulsion. It is generally used at room temperature, 60~ The baking effect is better at 80 °C. The customer should test according to the needs of the process. This product is a two-component cross-linking agent. Once added to the system, it is recommended to use it within 8 to 12 hours. Use the temperature and compatibility Resin system to test the pot life. At the same time, this product has a slight irritating ammonia smell. Care should be taken to avoid direct contact with skin and eyes. Try to use it in a ventilated environment. Pay special attention to mouth and nose during spraying. Should wear special masks, gloves, protective clothing to operate. |
