- For enhancing the hardness of pouring and moulding compounds
- High thermal conductivity (e.g. for deep-drawing dies
- For epoxy, polyester, and vinyl ester resins
Fine, powdery aluminium powder as an additive for pouring and moulding compounds. It enhances the impact and compressive strength of moulding compounds, and its low resin content helps to reduce shrinkage.
The aluminium powder is added as soon as the resin-hardener compound is ready for processing. Any quantity can be added.
Non-drip mixtures are obtained when the filling level is raised or a thixotropy-enhancing agent is also added.
For an aluminium mould resin the EP colourless gel coat can be used as a basis with the hardener S, L, or EPH 161. The aluminium powder is added to the ready mixture of EP gel coat and hardener. The mixing ratio is 100 parts by weight of resin/hardener to 100 parts by weight of aluminium powder. This yields a thixotropic, easily spreadable epoxy resin overlay that exhibits a high surface hardness and scratch resistance similar to aluminium mould resin.
