Non-PFAS Wetting Agents for Decorative Chromium(VI) Plating
This article is based on a presentation given at NASF SUR/FIN 2022, in Rosemont, Illinois, in Session 6, Responses to PFAS / PFOA. It follows the case study of three facilities’ conversion from PFAS-containing wetting agents to non-PFAS equivalents, eliminating PFAS and moving forward with a smaller and more sustainable environmental footprint. The journey of conversion from PFAS-containing wetting agents in both chromic-sulfuric etch and hexavalent decorative plating tanks can be complicated and winding due to deep rooted standard industry practices, as well as state and federal regulations. Outlined here is a clear course of action that led to eliminating PFAS from the facilities’ wetting agent strategies.

NASF Releases May 2022 Policy Update
The National Association for Surface Finishing has released its monthly Policy Update, summarizing some of the pertinent regulatory developments and new announcements from the month of May.
Read MoreCARB Releases Draft Regulatory Language for Chromium Plating Rule
In draft regulatory language, CARB bans hexavalent chromium plating processes, prohibits any new hexavalent chromium permits, and imposes strict new control measures until the bans take effect.
Read MorePFAS Legislation Introduced That Specifically Targets Surface Finishing
Legislation was recently introduced again in Congress that would require EPA to issue wastewater discharge limits for PFAS for electroplating and metal finishing source categories. Among other impacts, the measure would accelerate the PFAS rulemaking on which NASF is already working with EPA.

Developing Standardized Testing for Trivalent Chromium Thickness: A Progress Report
The industry shift toward trivalent decorative chromium plating and away from hexavalent highlights a need for testing standards. As Chair for ASTM B08.10 Subcommittee on Test Methods for Metallic and Inorganic Coating, Mark Schario is leading the committee’s focus on developing standardized testing for trivalent chrome thickness. This presentation provides information on the initiative, testing methods and variables, initial data on thickness comparison and alloy composition, and summary of input and extended lab testing.

NASF/AESF Foundation Research Project #122: Electrochemical Approaches to Treatment of PFAS in Plating Wastewater - 4th Quarterly Report
The NASF-AESF Foundation Research Board has selected a project on addressing the problem of PFAS and related chemicals in plating wastewater streams, studying PFAS destruction via electrooxidation and electrocoagulation. This fourth quarter report continues the work on electrocoagulation and electro-oxidation, measuring energy consumption and evaluating methods to remove residual zinc ions from the floc after processing.
