Material Description. This specification describes requirements and tests for an anaerobic resin intended for the impregnation of porous metal castings and powdered metal components. See 7.1.1

Symbols. Not applicable.

Applicability.

Application Limit. Intended as a single application to components that do not initially pass final leak test due to porosity in the metal.

Usage and Temperature Limits. After impregnation, under no circumstances should the continuous or excursion product temperatures of the material manufacturer be exceeded. This is a Class B product suitable for components operating in that continuous temperature range (shaded in Table 1). Discuss with the resin supplier the nature and frequency of the excursions before making a selection. See Table 1. Do not confuse this with storage shelf life, 3.7.5.

Process Sequence.

The product is applied after all heat treatments and before or after final machining.

This product is only intended to seal porosity and no other process defect.

Use of impregnation product is strictly a temporary measure to resolve a porosity condition. The condition limits under which use is allowed are defined in the Component Technical Specifications or the Statement of Requirements for the part or component. If no provisions are stated, no impregnation is permitted.

Precautions. Persistent use is not recommended as a preventative measure. The long term durability of this impregnation product is not known because it is rarely used. GMW3155 testing of impregnated parts is highly recommended to assist in defining long term sealing performance.

Expired Product. Even if properly stored (see 3.7.5), do not use this product past its expiration or use before date. Do not contact GM Materials Engineering and request permission to use expired product.
