I’ve been using shellac for a while, and have some experience, but I’m having a really strange experience, and could use some advice.
I had a still sealed bag of BT&C blonde Tiger shellac flakes. Mixed 1 oz of flakes into 8oz of Kleenstrip Green DNA; for a 1lb cut. It’s been about 5 days and it has not dissolved. There is still a slurry at the bottom of the glass jar; it has not melted together, as I’ve had happen sometimes if I forget to shake, but it doesn’t seem to want to dissolve further. It’s in my 67degree kitchen; so it shouldn’t be too cold. I’ve used the KS Green before and it has worked; usually takes about 24 hours and a lot of shaking, but works.
According to the MSDS, the Kleenstrip Green is 90% ethanol, with about 10% methanol and some of MIBK and ethyl acetate. The regular Kleenstrip stuff is about 50% ethanol, 50% methanol, and smaller traces of MIBK and ethyl acetate.
What brand solvent are others using with success? Anyone using the regular KS stuff?
Could a closed can of DNA actually pull enough moisture out of the air to make it ineffective? Could the higher levels of MIBK and ethyl acetate be causing problems?
Can a factory sealed bag of flakes (not even a year since I bought them) with desiccant packs go bad?
Any help would be appreciated. Thanks.
