Aziridine Crosslinker

Aziridine Crosslinker
XR-100 series
   产 品 说 明
Aziridine Crosslinker (XR-100)
Aziridine crosslinker (XR-100) can react with the carboxyl group at room temperature, so the polyfunctional aziridine cross-linker is a good crosslinker for carboxyl group-containing system. It is miscible with water and many organic solvents and can react with them under dry state. Dosage of the aziridine crosslinker is usually 1% -3% of the solid content of the acrylic acid or polyurethane. Both room temperature curing and heat baking curing can be applicable. The water resistance, chemical resistance, resistance to dry and wet rubbing, surface anti-adhesion, fastness and adhesion on special substrate of the coating can be significantly improved after it is crosslinked with the aziridine crosslinker.
