| Cast Nylon 6, a plastic of high molecular weight, 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. Addonyl® TT is an isocyanate crosslinker with a pyrogenous silicic acid (< 1%) as a fluxing agent. The additive is used as an activator during the production of cast nylon (PA-6 G). In combination with the catalyst Addonyl® Kat NL and other products from the Addonyl series users can combine various properties to tailor materials specifically to requirements. Addonyl® TT is used as an activator in cast nylon (PA-6 G) in order to extend the pouring time. Use: The reactivity of the polymerizing melt is influenced by various factors. Lanxess recommends an activator concentration of at least 0.5% by weight. The quantity of the activator to be used, however, decisively depends on the size and form of the casting mold.
