Standard Specification for Corrosion Protective Fastener Coatings with Zinc Rich Base Coat and Aluminum Organic/Inorganic Type

Abstract

This specification covers the basic requirements for chromium-free fastener coatings that combine an inorganic zinc-rich basecoat with an aluminum-rich topcoat that contains an integrated lubricant. These coatings are applied by conventional dip-spin, dip-drain, or spray methods to ferrous parts which can be handled through a cleaning, or phosphate, coating, and baking operation. Phosphating or shot blast is required to clean and prepare the surface of the steel. These coatings are bake cured at temperatures up to 500°F.

Scope

1.1 This specification covers the basic requirements for chromium-free fastener coatings that combine an inorganic zinc-rich basecoat with an aluminum-rich topcoat that contains an integrated lubricant.

1.2 These coatings are applied by conventional dip-spin, dip-drain, or spray methods to ferrous parts which can be handled through a cleaning, or phosphate, coating, and baking operation. Phosphating or shot blast is required to clean and prepare the surface of the steel. These coatings are bake cured at temperatures up to 500°F.

Note 1: If used, phosphate to be used in accordance with Specification F1137, grade 0.

1.3 Units—The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
