Hi Neil,
    As for the saturation of POLYFLUSH. I'm not familiar with values but I
have been using polyflush for about 8 months. Previously I used TPM for 10
years and I'm not turning back. I found out that I can leave my parts in
polyflush much longer than TPM. I'm talking about allot longer. I even leave
my parts soak overnight with no adverse effects. (Caution) Lately I have
noticed effects in thin areas with some resins when the resin becomes
saturated with humidity or if the resin is a soft flexible resin. There is
no guaranteed effects when you are working with chemicals.With TPM you hit a
saturation level of resin to the point to where the TPM does not work or the
parts come out sticky. I have not found this to happen with polyflush. My
parts have very small deep cavities that are hard to clean out. TPM does not
get down into those areas, especially when the TPM is saturated. The
polyflush continues to clean those areas out, even when the viscosity
saturation gets very high. When I say high, I mean the polyflush looks milky
and you can not see the bottom of the cleaning tank. I produce approximately
8,000 or so SLA parts per year and I can go as long as two to three months
on 5 gallons of polyflush. Lately I have not been taking the time to post
drain my resin from my parts and platforms. I do not have to be so conscious
about the saturation of the polyflush. Currently I change my polyflush every
month and a half. My goal is every month but I don't get the time to do it.
There is one negative. The polyflush is very slippery compared to TPM. You
will have to do a post rinse or dunk with alcohol. This will eliminate the
slippery nature. There is no bad chemical smell with polyflush. I hope I was
able to help.

Hi all,

I have some questions for anyone out there using POLYFLUSH to clean

their SLA resins before post curing.

Has anyone been able to determine the saturation values of POLYFLUSH

cleaner compared to TPM ?

Is the same method for determining the saturation values for TPM used

for determining the POLYFLUSH ?

Overall - has anyone an idea of how long the POLYFLUSH will last ? -

compared to TPM ?
