Addonyl® CR CATALYZE

Addonyl® CATALYZE is a solid solution of sodium caprolactamate in caprolactam. It has a weak characteristic odor.

The CastReady product range is ideally suitable for direct mechanical processing on two-component (2K) machines.

• Ready-to-use dispersion of catalyst for the anionic polymerization of ε-Caprolactam
• Homogeneous solid mixtures with a long shelf life
• Useable with different mashine technologies - RIM or T-RTM
• Short cycle life feasible - highly cost effective usage

 Possible machine technology RIM
Reaction Injection Molding (RIM) for small parts

1. Ideally suited for direct processing on two-component (2K) injection molding extruders
2. Can be used with existing, only slightly adapted machines

Possible machine technology T-RTM
Thermoplastic Resin Transfer Molding for large parts 

1. Ideally suited for direct processing on two-component (2K) injection molding extruders
2. Can be used with existing, only slightly adapted machines 

The reactivity of the polymerizing melt is influenced by various factors (temperature of the melt and mold, moisture). We recommend an Addonyl® CR CATALYZE concentration of at least 1:1 by weight with Addonyl® CR ACTIVATE. The caprolactam melt containing the activator is susceptible to oxidation. Thus, we recommend working under inert gas.

• Melt: 110 - 130 °C
• Mold: 130 - 160 °C
• Recommended Dosage: 1 part Addonyl® CR CATALYZE and 1 part Addonyl® CR ACTIVATE

• Addonyl® CR CATALYZE has a shelf life of at least 12 months if handled correctly.
• A receiving inspection is recommended. The catalyst is strongly hygroscopic. Opened containers should be resealed tightly immediately after product has been removed. The product is highly corrosive.
