iso ester, is there such a name?

iso ester resin??

is he just saying he using an iso 9001 something ester resin? or what. that’s a direct quote saying what type of resin i used.

he means vinly ester resin that meets ISO standards.

My knowledge and I have use both ISO or Ortho and they both were Polyester!

ISO is a tooling grade which will take multible heat cycles (making parts) much better than GP resins…
