VESTAMIN® A 139
Liquid, blocked crosslinker for polyisocyanate resins based on a cycloaliphatic diamine.
Exhibits a very low reactivity towards isocyanate groups. The crosslinking with polyisocyanate resins occurs under the influence of moisture by releasing the original diamine, which is spontaneously reacting with the isocyanate groups under formation of urea structures.
