Chemical Agent Resistant Coating (CARC)

1. BACKGROUND. CARC is a coating system that provides surfaces that are easily and effectively decontaminated after exposure to liquid chemical agents.

There are three types of coatings in the CARC system: an epoxy polyamide primer, an aliphatic polyurethane paint (PUP), and epoxy polyamide enamel. Each of the coatings is supplied as a two-component system. When the two components are combined, a terminal reaction begins which makes an impermeable coating.

2. APPLICATION. The surfaces to be coated with CARC must sometimes be stripped. After stripping, the surface must be cleaned of all oils, grease, and water. When the item is ready for coating, the two components are mixed and allowed to stand for a prescribed period. The mixture must then be applied within a given time period known as its "pot life" in order to be effective.

3. WASTE STREAMS. There are several waste streams associated with the application of CARC. The most common examples of waste are: unserviceable CARC components, CARC mixtures with expired pot life, spent thinners and stripping solvents contaminated with CARC, blasting media with dry CARC residue, and empty containers. Each individual waste stream must be handled and disposed differently.

4. ALTERNATIVES. The solvent based CARC systems are being phased out in favor of a water-dispersible (WD) or water based CARC paint system. Below is a table containing National Stock Numbers (NSNs) for the new WD CARC. There is at least one manufacturer with a GSA approved WD CARC paint touch-up system (This is not an endorsement, just a statement of availability). For more information regarding the touch-up paint system, please contact USAPHC using the information at the end of this fact sheet.

5. DISPOSAL GUIDELINES.

Unserviceable CARC components:

- Solvent Based CARC: reclamation is the best option, but if it is not possible, then they must be disposed as hazardous waste with the characteristic of ignitability, reactivity and possibly toxicity (heavy metals). Hazardous Waste Number/Code: D001, F003, and F005. Do not incinerate closed containers.

- WD CARC Part A: reclamation is the best option, however if not possible, then incinerate in a multi-chambered municipal solid waste incinerator of >50 tons per day capacity. Do not incinerate closed containers.

Certain colors (brown 383, 30051 and green 383, 34094) contain trivalent chromium and trivalent chromium only.

There is an exemption in the federal RCRA regulations for solid wastes that fail the TCLP test for chromium only (no other metal or any other characteristic/reason) and that the generator can prove that the chromium present in the waste is exclusively or nearly exclusively trivalent chromium (Title 40 Code of Federal Regulation (CFR) Part 261.4(b)(6)(i)). Your state regulations may not have this exemption so you must first coordinate with your installation environmental office and/or state regulatory agency before using this option.

-WD CARC Part B: reclamation is the best option. Waste must be tested to determine if it exhibits any characteristic of hazardous waste (ignitability). Non-hazardous waste should be incinerated in a multi-chambered municipal solid waste incinerator of >50 tons per day capacity. Do not incinerate closed containers.

CARC mixtures with expired pot life:

- Solvent based CARC: should be allowed to dry. The dried mixture may be disposed in a sanitary landfill if the paint contains no hazardous heavy metals. If the mixture contains any heavy metals (see MSDS), then it should be tested using the Toxicity Characteristic Leaching Procedure (TCLP) test and disposed accordingly.

- WD CARC: should be allowed to dry. The dried mixture may be disposed in a sanitary landfill if the paint contains no hazardous heavy metals (see exemption above).

Spent thinners and stripping solvents contaminated with CARC- Generally, all spent thinners are hazardous for the characteristic of ignitability (D001).

Blasting media with dry CARC residue- if the CARC contaminated dust is free of heavy metals then the waste may be disposed in a sanitary landfill. If there are heavy metals present (see MSDS), then the waste must be analyzed using the TCLP test and disposed accordingly.

Empty containers- containers that held any CARC component may be recycled or disposed as ordinary trash as long as they meet the definition of empty provided in Title 40 CFR Part 261.7(b).
