FAQ General Questions

Q1. I can't find the NFPA codes on the Ulano MSDSheets.

A1. Ulano uses the HMIS (Hazardous Materials Identification System) codes which can be found on on our
MSD sheets. The HMIS codes are very similar to the NFPA and the code numbering systems are identical.

Q2. Blue emulsions for graphics only?

My supplier recently reccomended a new emulsion. He said it was blue and it doesn't need to be sensitized. Also that its unlimited shelf life and exposes twice as fast. I have always thought that blue emulsion was for graphic printing.

A2. Pre-sensitized emulsion DOES NOT have an unlimited shelf life. 12 to 18 months in controlled storage, but not unlimited.

Pre-sensitized emulsion are usually fast exposing and a favorite for beginning textile printers with inferior exposure lamps. Because of the long shelf life you can also save money buying in 5 gallon pails, not gallons.

There is some basis for saying that red colored emulsions resolve a better image, but only under the best exposure and coating conditions. Blue emulsion is not just for graphic printing. Check any listing, from any emulsion company and you will see a range of colors from blue to red and others in between.

Q3. Are Ulano products phthalate free?

A3. We are proud that all Ulano Direct Emulsions, CDF™ Direct-Films, and Presensitized (Indirect System) Photographic Films have been phthalate free since 1989. Ulano TZ emulsions, CDF™/SR-25, CDF™/TZ, UlanoCUT Green water-soluble knifecut films and all gelatin-based Photographic Films have always been phlhalate free.

Di-Butyl Plithalaie (DBP), a plasticizer present in most direct emulsions and capillary films, is under scrutiny by state and local environmental authorities. The discharge by screen printers of waste water containing DBP is severely restricted in many stales.

Ulano laboratories eliminated DBP from our photographic products in 1989 without affecting ihe reliable Ulano performance that you have come to expect.
