36、ured or parallel) to insure 100% contact of the bond area. For maximum adhesion, tape should be applied to freshly painted surfaces. When tape is applied to part prior to assembly, the part shall not be subjected to a paint and bake cycle. Once a pressure sensitive tape-backed ornament has been bond

37、ed, and for any reason removed (in-plant pull test), it shall not be reused. If the adhesive surface of the pressure sensitive tape becomes soiled, the pressure sensitive tape-backed ornament should not be used. The adhesive side of tape, shall not be touched or handled, once release paper has been removed. 5.5 COLOR - Originally Released White 5.6 DENSITY - Originally Released 680 +/- 80 Kg/m3
