scope:

This specification covers the requirements for a sheet vibration damping heat fusible material intended for use on inverted vertical or horizontal surfaces. The material may come in the form of a single layer, constrained layer or a multilayer composite.

Material Description.

Heat fusible bitumen pads which are applied on painted sheet metal in order to provide a damping effect on the body. Before the paint shop oven these mats are to be set on the specific places what generates the following classification.

Type I:

A standard bitumen material with a hot melt adhesive and can be applied in the paint shop.

Type II:

A magnetic material with a hot melt adhesive and can be applied in the paint shop. The magnetic strength shall not be less than 18 mT.

Type III:

A material which comes with a pressure sensitive adhesive on the attaching surface to enhance adhesion for difficult to bond areas.

Type IV:

The same as Type I or Type II materials except with an epoxy restraining layer to induce stiffening.

Typical Applications.

Correlation between common panel position forms for part setting on the determined place before entering the paint shop oven for curing and examples of application. See Table A1.

Deadeners Materials Identification.

Heat fusible materials specifications identifications and equivalence between them. See Table A2.
