Sealer - High Bake Abrasion Resistant Coating
|Publication Date:||1 October 2014|
This specification details the requirements of a high bake paintable Polyvinyl Chloride (PVC) abrasion resistant coating/sealer. 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 interior and 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 standard production displacement pumping and robotic application equipment as follows: single point streaming, flat streaming, airless spray, manual tip and flow brushing. It must not have a noxious or toxic odor in either the uncured or cured state. In addition, the material must not adversely affect personnel handling it.
The material must adhere to all approved production E-Coat substrates. It must have good durability and not accelerate the resting of steel over which it is applied.
Symbols. Not applicable.
Applicability. Vehicle rocker, underbody or seam sealing in paint shop.
