Can someone give me a supplier contact for PolyFlush.
Can you use PolyFlush in Ramco systems.

Thanks for this info - this truly helps.
I will follow with feedback from our lab in due course.

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.Bob ZubrickieTyco Electronics

Subject: POLYFLUSH info
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 ?
