Hi All, once posted other another handle here at Sways, but overtime have forgot it and lost the email it was connected too. Starting fresh…
I have been hotcoating a few boards here and am having continuing issues with resin seperating in random areas across the surface of a board. Has happened more than once, on the last few runs that i have done. Tried a search, but can’t seem to find the same information here on sways.
For the record
-
All work is being done with Resin Research standard epoxy, standard hardener. (Sorry, exact specs i don’t know off the top of my head). The resin is about 2 years old, but still cures with out issue and shows no signs of age.
-
I use a small digital scale for measurement by wieght. Im told this is slightly inaccruate but have not had a curing issue as of yet?
-
All surfaces are wiped down with acetone and a clean rag.
-
Few drops of ADD F that is showing its age with small amounts of crystalization in the bottle is added
What i come back to see, even after leaving that nice clean shiny finish over the entire surface are these areas of random size and shape where the resin seems to have been pushed away and the bare cloth is exposed or only slightly covered by epoxy. I can even deliberatly drip epoxy on these areas, rub it in, usually about the size of a penny or quarter, and return to still find tbe resin seperating from these spots.
Tried to take a photo but tough to pick up anything visually. can try again tonight
Anyways, sounds like i have a contamination issues, but with the acetone wipe, i thought i was getting the fingerprints already off??
Any help would be great, much appreciated.
Cheers. I apologize for my spelling
