Ebalta Kunststoff - MG 804MG 804 1 - Polyurethane

Identification & Functionality

Features & Benefits

Materials Features: Good Impact Strength
Properties: long potlife
very well castable
good impact strength
easily dyeable
low agressivenes against silicones
RoHS conform

Applications & Uses

Markets: Industrial
Applications: Industrial — Chemical & Industrial Manufacturing
Tooling & Moldmaking
Compatible Polymers & Resins: Acrylonitrile Butadiene Styrene (ABS),
Polyamides
Plastics & Elastomers End Uses: Modeling Material
Plastics & Elastomers Processing Methods: Casting
Applications: High quality prototypes, like ABS
High quality prototypes, like PA
Processing Instructions: 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 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.

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
