Hairspray Ingredients and Information

Here is a Hairspray known not to work according to user Pigeon. FX
“I can confirm L’OREAL Elnet Satin EXTRA STRENGTH (with PRO-KERATIN) did not work”
And this is a re-post of information provided by my fellow 3D printer engineer and guru  Ryan Carlyle (not to mention chemistry is another facet of his expertise):
Note, this discussion was about why some masking tapes seemed to work better than others- Hint- all about the glue and how it affects the tape.
In other words, literally every known solution works on the same bonding principal and chemical nature. All beds that work are chemically related.
And that’s a huge hint to massive question about Wanhao masking tape- most likely acrylic based glue and since that glue is one of the listed chemical compounds that Ryan describes and since acetone is a solvent- that just solidifies the answer. Given that there are 3 common type of glue used or PSA (Pressure Sensitive Adhesive) rubber-based, acrylic-based, and silicone-based. I just said silicone is not going to work and since acrylic adhesive is a type and known to be a bonding agent in the explanation by Ryan, I’d say it’s a safe bet.
Ryan posted a great snippet of info on what chemicals are used for bed surfaces and the detailed chemical analysis:
While it doesn’t explain what glue is used on tape in your case, a good bet that it’s similar in nature to one of the combos below. That’s why I said that Acetone is good bet that it wouldn’t hurt the PLA but would remove the glue. Alcohol is less reactive but a good second best, and is usually the first solvent I try and keep on hand in the house. I only break out Acetone for the really tough jobs.
Ryan Carlyle:
Most of the popular build surfaces have very similar underlying chemistry. That’s because they all rely on diffusion welding for adhesion. The molecular chains at the interface slightly dissolve into each other.

Gluestick active ingredient –

Aquanet and liquid PVA glue active ingredient –

If you’re familiar with organic chemistry, what you see here is an identical polyvinyl backbone chain, and functional groups that both have a ketone/ester double-bonded oxygen adjacent to a space-filling component. (The space-filling component probably decreases adhesion so the print can be released.) And guess what? Permanent build plate surfaces rely on the same underlying chemistry:
Lexan also has exposed double-bonded oxygen on a polymer backbone:

Kapton also has exposed double-bonded oxygen on a polymer backbone:

Acrylic also has exposed double-bonded oxygen on a polymer backbone:

PET also has exposed double-bonded oxygen on a polymer backbone:

Now, if you look at some common solvents for filaments, what do you often see? Double-bonded oxygen on small molecules. Here’s ethyl acetate (dissolves PLA) and acetone (dissolves ABS):

These molecules are still diffusing into the filament polymer, but they’re so small and mobile that they are able to completely liquefy and dissolve the plastic.

Isn’t chemistry great?
