> Bruce,
> Thank you very much for your detailed reponse to my questions. I shared
> your information with our pattern shop foreman and he was familar with
> accelerators and "lightners" you mentioned. Since our pattern shop is
> temperature or humidity controlled (other than heat in the winter) we
> to use some work-arounds to use this resin (Ciba RP 6470) successfully.
> The shop foreman says that they have to cast it and then pull it out of
> mold ASAP, then they put it back into the mold and recast a face coat on
> to fill in for the shrinkage. This seems like a more time consuming
> but given our facilities budget, I guess this is what we have to live
> for now.
> Again, thanks for your suggestions.
