Description / Abstract:

This specification describes flat-backed paper tapes, films. and single coated foam tapes used to provide shipping protection for materials to prevent damage to their finish. The tapes must not have effect on the surface to which they are applied. They must not cause any surface etching, softening of the finish. finish discontinuities. latent staining or other objectionable effects when they arc removed. They must be easily removed without themselves tearing or removing the finish from the item being protected.

This specification does not cover paint protection transit films applied to a vehicle's horizontal surfaces. Refer to 9984168 for film transit comings.

Tapes covered by this specification are coated with a removable pressure sensitive adhesive. The adhesive system must be pressure sensitive over the range of -20'C to 95'C. The tape must not show any mass transfer upon removal.

Tapes specified here are of 4 basic types (Type I. Type H. Type 111, and Type IV), with 2 grades (A and B) for each.

Type I. This is a flat-backed paper tape used for sur-face protection where transparency is not requited.

Grade A. This grade uses a latex based adhesive and it should not be used to protect surfaces to be cut or drilled. In addition to metal surfaces, this grade should be used on plastic and paint finishes when greaser surface compatibility may be requited. Nevertheless, each application should be proven on an individual basis.

Grade B. This grade uses a solvent based adhesive and is used on polished metal finishes where cutting, drilling, and processing is involved since it will not string out or ball up on cutting tools.

Type II. This is a transparent plastic film tape used where it is necessity to inspect the item being protected and where a non-aggressive adhesive compatible with plastic and paint finishes is required. The film must protect the part during shipping and handling. The film and adhesive must not be affected by heat or ultraviolet light such that the film team or slivers during removal. adhesive mass transfer results, the fin-ish being protected is removed, or otherwise effected, or staining results. Opaque plastic films, and various film colon can also be used. The film color will be specified on the engi-neering drawing.

Grade A. This grade is used for the protection of molded or extruded interior plastic pans and is to be removed by the dealer at the time of delivery. It is to be used for pro-tecting pans during shipping from the molder to the assembly plant and consequently to the delivering dealer. Approval of tapes for this grade must be done on each specific substrate on which the material intended is to be used.

Grade B. This grade is used on the exterior to pro-tem paint and plastic during shipping from the assembly plant to the dealer, to be removed at time of delivery. It is intended to be used in conjunction with the door protector assembly. This grade must be compatible with all of the present exterior body topcoat systems.

Type III. This type is similar to Type II Grade B except with the addition of a scratchrmutilaticm test require-ment. Films approved to this type provide additional scratch, mutilation resistance versus Type II.

Grade A. A mannal is for in-plain use only, and is removed before the vehicle leaves the plant.

Grade B Material remains with the vehicle during shipping, and is removed by the dealer.

Type IV. This is a single coated foam tape used to protect door edges from scratches and dents.

Grade A material remains with the vehicle during shipping, and is removed by the dealer.

Grade B material is for in-plant use only, and is removed before the vehicle leaves the plant.
