- Processing Instruction
Stir up comp. A before use, since additives tend to sedimentation. Higher heat resistance is reached with MG 804-1. To get a better E-modulus, e.g. more stiffness of the parts glass fiber paste MG 804 new GF could be used. With only this product the maximum stiffness can be achieved. 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
