Cement film is a special glue designed to join motion picture film. It is made of film base dissolved in a solvent . Two cut sections of film are spliced together in a film splicer using film cement. [1] [2] [3] Splices can be made with a “hot” splicer, or the splicer unplugged at room temperature . It is most important that the emulsion of the film be scraped off prior to applying the cement or the splice will fail. Film cement also has a workable life span, if the amount of solvent falls below a certain level the splices will fail. Cement life can be extended by the care of its solvent, usuallyMethyl ethyl ketone (MEK) or acetone . [4] [5]
Film cement can only be used with Acetate , Triacetate and Nitrate films. Cement film can be used with polyester based film. [6] [7]
