TM 1-1500-204-23-1 NOTE Reactivate adhesives which have dried with cyclohexanone,or equivalent, prior to installation. Adhesive may be reactivated as many as three times without damage to adhesive capability. Adhesives which are reactivated will be allowed to air-dry thor- oughly before application. 3 Remove cellophane backing, but do not touch adhesive, NOTE Apply a few drops of aliphatic naphtha, Fed- eral  Specification  TT-N-95,  to  the  adhesive when  room  temperature  is  below  72°F (22°C). (d) Position decal in proper location, while adhesive is still tacky, with only one edge contacting prepared surface. (e) Work  roller  across  decal  with  overlap- ping strokes until all air bubbles are removed. Drycleaning  solvent  is  flammable  and  sol- vent  vapors  are  toxic.  Use  P-D-680,  Type II Solvent in a well-ventilated area. Keep away from open flames. Avoid prolonged solvent contact with skin. 4 Position one edge of decal onto pre- pared  receiving  surface.  On  large  foil  sheet,  place  center onto receiving surface and work outward from center to edges. 5 Remove all air pockets by rolling firmly with a rubber roller, and press all edges tightly against receiving surface to ensure good adhesion. (b)  Removal. Remove metal decals by moistening edge of foil with aliphatic naphtha, Federal Specification TT-N-95, and peeling decal from adhering surface. (2) Removal. Remove vinyl film decals by plac- ing,  a  cloth  saturated  with  cyclohexanone,  or  methyle- thylketone, ASTM D740, on decal and scraping film with a micarta scraper. Remove remaining adhesive by wip- ing  with  a  cloth  dampened  with  drycleaning  solvent,  Fed- eral  Specification  P-D-680. c.  Metal  Decals. Metal  decals  come  in  three  types: cellophane-backing adhesive type, paperbacking adhe- sive  type,  and  no  adhesive  type.  Application  and  removal procedures for each type are explained in the following paragraphs. (2)  Paper-backing  adhesive  type.  Application and  removal  of  paper-backing  adhesive  are  explained  in the following paragraphs. (a) Application. Apply metal decals with paper  backing  adhesive  in  accordance  with  the  following procedures: 1 Remove paper backing from decal. 2  Apply  very  light  coat  of  cyclohexanone, or equivalent, to adhesive.
