It seems to be recommended that 3D printed items be cleaned with Bestine prior to painting. Never having used this before, I have the following questions.
May the Bestine be poured into any convenient container or does it have to be something special (metal/plastic/glass)?
After using the Bestine, can the remainder be poured back into the can, or does it have to be disposed of due to contamination?
Any special disposal requirements, or can it be poured down the drain or dumped in the back yard?
NIOSH: The recommended airborne exposure limit is 85ppm averaged over a 10-hour workshift and 440ppm, not to be exceeded during any 15 minute work period
You can’t smell it until 230 ppm
Toxic to aquatic life.
It has a very low flash point 27 F. Another reason not to pour it down the drain, as it will float on top the water.
Sir, you are correct. They state a gas or a liquid can be a solid. I took chemistry, organic chemistry and biochemistry and this is the first I’m hearing of this. [^o)]
If I had a well, I wouldn’t be dumping heptane on the ground.
After reading the safety data sheet for heptane, I would not want to have that stuff in my home. It´s highly flammable, skin irritating, aqua-toxic, and can be fatal when swallowed or inhaled.
If the bestine is removing contaminants prior to painting and those contaminants would affect the quality of your paint job (particles, uncured paint, etc.) then I would be hesitant to the possibility of re-introducing them to the surface of your 3D-printed part using pre-used solvent.
