High quality prototypes, like ABS
High quality prototypes, like PA- Processing Instructions
Stir up comp. A before use, since additives tend to sedimentation.
Individual formulation of E-modulus by adding glass fiber paste. Following instructions for mixing ratio!
To get more stiffness of the parts glass fiber paste MG 804 GF could be used.
Due to higher viscosity the casting has to be made in a vacuum chamber.
Further data sheets:- MG 804 /MG 804-1;
- MG 804 GF/MG 804-1;
- MG 804 , MG 804 GF/MG 804-1
Processing parameters: Temperature of resin: 20-30°C / Temperature of mold: 60 - 70°C.
In order to get bubble-free parts, we recommend working under vacuum.
Straight before casting, we recommend a one-time air impact from 10 of 60-70 mbar.
Mouldmaterial: we recommend silicone molds, for example Silastic® RTV 4234-T4
