About This Item
ASTM D964 is the standard specification for metallic copper powder intended for use in antifouling paints. It provides a technical reference for a material used in coatings where controlled copper content and consistent powder characteristics can matter for performance and product consistency. For buyers, formulators, and quality teams, this ASTM standard helps define a common basis for evaluating copper powder used in marine and other antifouling coating systems.
Purpose of ASTM D964
The purpose of ASTM D964 is to establish a specification for metallic copper powder when it is selected for antifouling paint formulations. As a specification, it is meant to support consistent material expectations and clear procurement criteria rather than to describe a finished coating system. In practice, it helps align suppliers and users around a recognized technical document, which can support quality control, product comparison, and specification-based purchasing for coating raw materials.
Common use cases of ASTM D964
This standard is commonly used when metallic copper powder is being sourced, reviewed, or specified for antifouling paint applications. It is relevant in coating formulation work, incoming material checks, and procurement of raw materials intended for paints that rely on copper-based antifouling performance. ASTM D964 may also be used by manufacturers and laboratories that need a shared reference for material acceptance and documentation during production or supply-chain review.
Why ASTM D964 matters
ASTM D964 matters because antifouling paint performance depends in part on the consistency of the copper powder used in the formulation. A clear specification helps reduce ambiguity during buying, testing, and production, which can support more reliable material control and less variation between batches. It also gives customers and suppliers a common benchmark for compliance discussions, helping streamline product evaluation and reduce risk in technical and commercial transactions.
