It's my experience that they are all the same. They are the same basic chemicals. Some of the solvents differ slightly but they are basically the same solvents. Temperature has everything to do with how fast the solvents evaporate as far as fume density is concerned. *0% of the time I use vinyl gloves because of the mess.
I've been working with epoxy , vinyl, polyester and urethanes for 35 years building planes and repairing cars. I work in a basement that has some ventilation and I don't ware respirators while fiberglassing and filling. I have never had any skin reactions. I always practice hygienic procedures as explained in Gorden Brothers guides[ wash your hands and exposed areas. [I use lacquer thinner and soap] I have used safetypoxy and aeropoxy and west resins and hardeners. I believe saftypoxy is the strongest of the three according to lab tests. I don't panic because some chemicals are called hazardous by the EPA just use common sense and read the manufactures procedures for the applications. [ some manufactures directions are in the CYA vain however] Just use common sense. Be aware and careful of the individual chemicals, after they react [cure] they are neutral. If the fumes are to much turn on a fan. Urethanes are a different matter when painting but not as a adhesive. KRron
