Hi!

Can I make Epoxy tooling for casting polyester resin parts, or there are problems between these two? 
Can I make Epoxy tooling with UG1 Uni-Mould Tooling Gelcoat or I need to use Epoxy Tooling Gelcoat?


Thanks

Generally the problem is the other way round, epoxy in polyester.  So you should be able to make a mould from epoxy and use it to make polyester parts.  If you are only making polyester parts then a traditional polyester based mould system would likely be a cheaper option. 

The Uni-Mould System uses a Vinylester tooling Gelcoat which means it is fine to make epoxy, polyester and vinylester parts in a Uni-Mould tool.

Uni-Mould is virtually zero shrinkage due to the fillers when compared to traditional polyester resins.
