Excellent mechanical properties provide for a trouble-free demoulding. Negative forms made of HY-E620 can be filled several times without losing their precision. The surface of the duplication model is smooth and hard without any additional treatment.
· Due to the short hardening time models can be demoulded after only 20 minutes. This saves time in the working process.
· Forms are almost shrinkless and have a high form consistency and long lasting dimensional stability thanks to the use of a platinum hardener system.
· Optimum adaptation to the mixing and dosing unit Dosper ensures premium material quality standards.
