INV P360 Aziridine Crosslinker Curing Agent

Products Overview

P360 is a trifunctional aziridine crosslinking agent, widely used in leather , textiles, inks, coatings, pressure-sensitive adhesives, adhesives, curing agents and other fields, the resistance to washing, scrubbing, chemicals, and adhesion on the substrate of its cross-linked film-forming products have been significantly improved; The cross-linking agent is an environmentally friendly cross-linking agent, no harmful substances such as formaldehyde are released after cross-linking, and the finished product is non-toxic and tasteless after cross-linking; the addition amount is usually 1-3% of the solid content of the emulsion, and the pH value of the emulsion is 8- It is best to add at 9 o'clock, and it should not be used in acidic medium (PH<7);

P360 mainly reacts with the carboxyl groups in the emulsion, and is also catalyzed by strong acid It can undergo cross-linking reaction with amine groups and hydroxyl groups, so aprotic organic base should be used as much as possible when adjusting the pH value of the system; the aziridine cross-linking agent can undergo cross-linking reaction at room temperature, but it should be baked at Baking effect is better; this cross-linking agent is a two-component cross-linking agent, once added to the system, it should be used within two days, otherwise it will form part of the gel;

P360 cross-linking agent can be miscible with water and common solvents, so usually It can be directly mixed into the system under vigorous stirring, or it can be dissolved in water and solvent before adding to the system;

Recipe Recommendation

Cross-linking agent P360 is a trifunctional cross-linking agent that can be combined with polymers The carboxyl group of the carboxyl group undergoes a cross-linking reaction (equivalent number 166); in most cases, the best improvement effect can be obtained when each equivalent of carboxyl group reacts with 0.6 equivalent of P360, but some systems require an equivalent amount of cross-linking agent to react with it; generally Under normal circumstances, 2% or 3% P360 (calculated by weight) is required to crosslink all acrylic or polyurethane dispersions. P360 should be added before varnishes, coatings and inks are used. Due to its excellent miscibility, it can be used manually Just stir, the best way is: first mix P360 with water 1:1 and then add to the system.
