About this file
This is a specification document for paint and primer coatings issued by the New Hampshire Department of Transportation (NHDOT) dated February 14, 2013. The specification establishes requirements for coating supplies and paints applied to equipment provided to NHDOT, with particular emphasis on durability under severe exposure to road salt and abrasion. All coatings must comply with federal and state regulations regarding chemical and volatile organic compound (VOC) content, and are prohibited from containing compounds that would render dried paint a hazardous waste under NH Code of Administrative Rules Chapter Env-Hw 400. Coatings must not exceed 2.8 lbs/gal total VOC content and are explicitly prohibited from containing hexavalent chromium or cadmium. The specification requires solids content between 45-60% by volume and 55-70% by weight, with dry film thickness of 1-2 ml and practical coverage of 325-650 square feet. Dry times must achieve tack-free condition within 4-6 hours, handle capability in 12-16 hours, and recoat readiness in 24 hours at standard conditions.
Suppliers must submit written certificates of conformance with accompanying laboratory test results demonstrating compliance with toxicity characteristics specified in NH Code of Administrative Rules Env-Hw 403.06, Table 4.9; Material Safety Data Sheets alone are insufficient documentation. Testing must be conducted using specified ASTM methods D3335-85a, D3718-85a, EPA Test Method 1311 (TCLP), and EPA Test Methods 3010A/6010B, with alternative methods available upon written approval. All bulk coating supplies must be packaged in 1-gallon containers. Representative products meeting these specifications include Sherwin Williams Industrial Enamel HS, Sherwin Williams Primer B50NZ003, Guertin Coatings Supershield Topcoat, Guertin Coatings Epoxy Primer, Akzo Nobel Powder Coating Textra, and Devoe High Performance Coatings Devguard 4309 Rust.

SPECIFICATION
Paint and Primer Coatings
This specification is for paint and primer (coating supplies) provided to NHDOT and for primer and paint coatings utilized on equipment supplied to NHDOT.
All coating supplies and coatings utilized on equipment surfaces that are normally primed and painted shall be suitable for severe exposure to road salt and abrasion. Coatings shall conform to all applicable federal and state regulations and criteria pertaining to chemical and VOC content.
Coatings containing any compound that would render the waste paint, in its dried form, a hazardous waste per NH Code of Administrative Rules Chapter Env-Hw 400 are prohibited. This includes RCRA listed metals (e.g., Arsenic, Barium, Cadmium, Chromium, Lead, Mercury, Silver, Selenium) other than naturally occurring trace amounts associated with the coating pigments.
The intent of this specification is to obtain or utilize paint such that any concentration of these metals shall not produce a TCLP test result that would fail NH DES toxicity characteristic standards and meets the latest governing regulatory criteria.
Coatings shall not contain hexavalent chromium or cadmium. For the purposes of this specification, a coating product "contains hexavalent chromium or cadmium" if hexavalent chromium or cadmium was introduced as a pigment or as an agent to impart any property or characteristic to the coating during manufacturing, distribution, or use of the applicable coating. Coatings supplied shall not contain a total VOC content greater than 2.8 lbs/gal (340 g/l).
A written certificate of conformance to these specifications shall be submitted to NHDOT, for coatings utilized on equipment supplied to NHDOT, indicating these compounds do not exceed
Toxicity Characteristics of NH Code of Administrative Rules Env-Hw 403.06, Table 4.9, Regulatory Limits. Material Safety Data Sheets are not sufficient documentation of conformance. Laboratory test results must be supplied with the written certificate. The following test methods are incorporated by reference herein, and shall be used to test coatings.
1. American Society for Testing and Materials (ASTM) Method D3335-85a (1999), Standard
Test Method for Low Concentrations of Lead, Cadmium, and Cobalt in paint by Atomic
Absorption Spectroscopy.
Date: February 14, 2013
2. American Society for Testing and Materials (ASTM) Method D3718-85a (1999), Standard
Test Method for Low Concentrations of Chromium in paint by Atomic Absorption
Spectroscopy.
3. EPA Test Method 1311 – TCLP Toxicity Characteristic Leaching Procedure.
4. EPA Test Methods 3010A/6010B.
5. Alternative methods which are shown to accurately determine the concentration of hexavalent chromium or cadmium compounds in a subject coating product or its emissions may be used upon written approval.
The coatings also shall meet the following criteria:
• Solids Content o % By Volume 45- 60 o % By Weight 55 –70
• Recommended Dry Film Thickness 1 – 2 ml (Bulk Orders Only)
• Wet Film Thickness to Achieve 2 ½ - 4 ½ ml (Bulk Orders Only)
• Practical Coverage at DFT 325 – 650 sq. ft.
• Dry Time (70 – 80 F and 50% humidity) o Tack Free 4 – 6 hours o Handle 12 – 16 hours o Recoat 24 hours
All bulk coating supplies shall be packaged in 1-gallon containers.
The following paints are indicative of the type of product required.
