Description / Abstract: This specification details the requirements of a paintable polyvinyl chloride (PVC) abrasion resistant anti-chip coating/sealer. The purpose of this material is to protect the metal substrate from stone damage that could result in corrosion. The material is applied in the paint shop after electrocoat (e-Coat) and baked. It must be capable of being either robotically or manually applied and is used to coat the rocker panels, underside of floorpan and underbody seams of vehicles to provide a high level of chip and abrasion resistance.

In addition, the material may be used as a sealer to seal exterior body joints against water, dust, air intrusion and corrosion. The material must be compatible with primer surfacer and topcoat systems.

Material Description. The material must be a smooth and homogeneous mixture free of air, lumps, unmixed particles, or foreign materials.

It must be capable of being dispensed with approved and validated production displacement pumping and application equipment.

It must not have a noxious or toxic odor in either the uncured or cured state.

In addition, the material must not adversely affect those personnel handling it.

The material must adhere to all approved production e-Coat.

It must not have corrosion causing ingredients.

Symbols. Not applicable.

Applicability. Coating of exterior surfaces of the rocker panels, floor pan and underbody seams after e-Coat in the paint shop.

Remarks. None.
