Smooth topsheet without fiberglass textures imprint
Posted: Tue Feb 27, 2018 10:53 am
Hi guys, have not been here for a while. I see you all grew up here discussing serious problems such as the use of graphene and 3-d base technologies))
I just returned from veneer topsheets to plastic ones and did a series of experiments with ICP 8210 (PA), 8100 (PA) and 4160 (PBT).
May be I am too picky, but have you any ideas how to get absolutely flat and smooth surface without fiberglass imprint on topsheet?
I have seen that even serial manufacturers have visible fiberglass on the topsheet but it's flat to the touch.
I figured out that the thicker topsheet the less textured topsheet? especially if you use backcoat. The worst result shows PBT...
I pressed samples from 15 to 60 psi and got approximately the same result (soon I will hare some pics)
My bet, the reason is lies on thickness of those materials. And may be too thin epoxy.
Any ideas, or may be it is normal and nothing to worry about))
Thank you in advance!!!
