Dear Chompoo san
As you know, we can’t dispose it without any reason.
If we get same properties , we can consume it. So please recheck.
OK, Next time please check only 3 item
1.Turbidity after mixing hardener.
2.Coating appearance after mixing hardener (3h.PET film)
3.Viscosity for each condition, if we need we will change test condition.
I want to attend the checking of viscosity next time.
(You can omit checking QC item next time. No need to recheck HP.)
Thank you for cooperation.
Best regards,
Shimizu
