Pentaerythritol tris [3-(1-aziridinyl) propionate] (CAS 57116-45-7, commonly abbreviated as PTAP, and often marketed under the name HD-110) is a tri-functional nitrogen-pyrrolidine type crosslinking agent. Its primary application is to efficiently crosslink active hydrogen groups such as carboxyl, hydroxyl, and amino groups in aqueous systems, significantly enhancing the water resistance, solvent resistance, adhesion, and mechanical properties of coatings, adhesives, and inks.

1. As Leather improve wet rub resistance, wear resistance and heat resistance of dry, applied primer and coating, can improve the coating adhesion and embossing moldability;
2. To Increase the film adhesion to different substrates, avoiding dragging phenomena during printing ink, ink enhanced resistance to water and chemical resistance, accelerate the curing time;
3. Enhanced adhesion to different substrates face paint, paint to improve resistance to water scrub resistance, chemical resistance, abrasion resistance and high temperature strength;
4. Improve water-based paint to water and chemical corrosion resistance, curing time, reduce volatile organic compounds, enhanced scrub resistance;
5. Improve the adhesion of the protective film coating, shorten the curing time.
6. Aqueous systems can generally improve adhesion on non-porous substrates.
