This specification details the physical and performance requirements for preformed (non-pumpable) sealer materials that are formed into parts. The parts are installed manually in the Body Shop to seal body joints from water, dust, and air intrusion. High-expanding versions of these sealers are used in baffles, which are intended to fill cross sections in body cavities and reduce airborne noise. The sealer material will expand and cure in the Paint Shop Electrocoat or Electrodeposition (ELPO) oven.

Material Description. Materials approved to this standard may be either tacky or non-tacky.

Tacky (T). Tacky sealer materials may be formed into parts which are applied directly to oily metal. The parts must remain in position in the uncured state up to and throughout the pretreatment and electrocoat processes.

Non-tacky. Non-tacky sealer materials generally require a carrier or fastener to hold sealer materials in place in the uncured state, up to and throughout the pretreatment and electrocoat processes. Parts made from these materials must allow sufficient clearance between the uncured part and the adjacent metal to enable electrocoat coverage behind the part and therefore prevent corrosion.

Symbols. Not applicable.

Applicability. These materials are applied manually in the Body Shop.

Remarks.

These materials are not intended to be weldable or fuel resistant, or applied in the Paint Shop.

Submission Package. A submission package must be submitted for final approval of a material to this specification. The submission package shall contain a submission letter, product data sheet, panel preparation data, test data and results, bake charts, and Production Part Approval Process (PPAP) warrant data. Test panel performance shall be photographically documented, able to be transferred electronically, and retained with the submission package.
