Addonyl® 8073 is a high-molecular weight polyol. It is produced through an anionic polymerization of caprolactam. During the pressureless casting process the monomeric caprolactam melt is poured into the mold and directly polymerized by a specific chemical reaction and then forms a semi-finished product or molding. It is used in combination with the catalyst Addonyl® Kat NL and the activator Addonyl® 8120 during the production of cast nylon (PA-6 G). Also used in rotomolding to prevent the formation of voids and pinholes. Its recommended dosage rate is 0.3 - 2.0 % by weight.
