Hi, How can I avoid bubbles in the castings when using Xencast (currently general purpose)? The mould is dry but there are always bubbles present, often on the surface ruining the castings.
Many Thanks

We can trace an exact expiry date through the batch number but for this resin it is 6 months from date of manufacture which, due to us having very short turnaround times means you can assume 6 months from ordering.   Also in practice, most resins will, if kept properly, still work after the expiry date but the properties will begin to degrade the older the resin is.  Some resins last a long time (eg most epoxies) and others less - PU's and polyesters for example.
