product description

     P350 is a trifunctional aziridine crosslinking agent with no solvent and solid content greater than 99%. It is widely used in leather, textile, ink, paint, pressure sensitive adhesive, adhesive, curing agent and other fields. After the cross-linking film is formed, the product's resistance to washing, scrubbing, chemicals, and adhesion on the substrate are significantly improved; the cross-linking agent is an environmentally friendly cross-linking agent, and no harmful substances such as formaldehyde are released after cross-linking. , and the finished product after cross-linking is non-toxic and odorless; the addition amount is usually 1-3% of the solid content of the emulsion, the best addition is when the PH value of the emulsion is 8-9, and it should not be used in an acidic medium (PH<7). This cross-linking agent mainly has cross-linking reaction with carboxyl groups in the emulsion, and can also cross-link with amine groups and hydroxyl groups under strong acid catalysis. Therefore, aprotic organic bases should be used as far as possible when adjusting the pH value of the system; The cross-linking reaction can occur at room temperature, but the baking effect is better at 60-80 degrees; the cross-linking agent is a two-component cross-linking agent, once it is added to the system, it should be used within two days, otherwise it will form partial condensation. glue phenomenon. The crosslinking agent is miscible with water and common solvents, so it can be directly mixed into the system under vigorous stirring, or it can be dissolved in water and solvent before adding it to the system.
