Random thoughts from someone who has handled a lot of various adhesives.It cleans up with acetate pretty well. I always wear disposable latex gloves
Use vinyl gloves, not latex gloves. Latex are popular because they are common in the medical community. They are effective for medical purposes in that the things they are trying to keep a distance from, bacteria and viruses, won't permeate through latex, these little buggers are too large.
Chemicals such adhesives can permeate through latex. As a polymer film, latex is really quite porous at the molecular level. Vinyl, on the other hand, (pun unavoidable) is far less permeable to chemicals and is the preferred material for protection when handling epoxies. This is actually quite important in that some of the starting chemicals that are used when making the resins are amazingly toxic. No process is perfect, chemical equilibria being what they are, and there is always a detectable, minute amount of the starting compounds in the final resin.
I just bought a box of 100 vinyl gloves at Coscto for $4.50. I personally know what is in many of these adhesives and will use vinyl every time I handle the various adhesives we use.
Cheers,
Bill
