product description  

P360 is a trifunctional aziridine cross-linking agent, which is widely used in leather, textile, ink, paint, pressure-sensitive adhesive, adhesive, curing agent and other fields. Chemicals and adhesion on the substrate have been significantly improved; the cross-linking agent is an environmentally friendly cross-linking agent, no formaldehyde and other harmful substances are released after cross-linking, and the finished product is non-toxic and odorless after cross-linking; the amount of addition Usually it is 1-3% of the solid content of the emulsion, and the PH value of the emulsion is best to be added when the PH value is 8-9. Do not use it in an acidic medium (PH<7);

P360 mainly undergoes cross-linking reaction with carboxyl groups in the emulsion, and can also undergo cross-linking reaction 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; this aziridine cross-linking agent 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 part of the gel;

P360 cross-linking agent is miscible with water and common solvents, therefore, 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;

recipe suggestion

Crosslinker P360 is a trifunctional crosslinking agent that crosslinks with the carboxyl groups of the polymer (166 equivalents); in most cases the best improvement is obtained by reacting each equivalent of carboxyl with 0.6 equivalents of P360 However, some systems require an equivalent amount of cross-linking agent to react with it; in general, 2% or 3% of P360 (by weight) is required to cross-link all acrylic or polyurethane dispersions. P360 should be used in varnishes, coatings and The ink is added before use. Because of its excellent miscibility, it can be stirred by hand. The best method is: first mix P360 with water 1:1 and then add it to the system.

Use and Toxicity

This product has a slight ammonia odor. After long-term inhalation, it will cause cough, runny nose, and a kind of false cold symptoms; contact with the skin will cause skin redness and swelling, and even goosebumps according to the resistance of different people, but the above symptoms are generally in It will disappear on its own within 2-6 days, and in severe cases, follow the doctor's instructions for treatment. Handle with care and avoid direct skin and eye contact, although use in a ventilated environment. When using spraying, special attention should be paid to mouth and nose inhalation, and special masks should be worn for operation.
