Its resistance to chemical fumes, mists, and splashings is generally considered to be good, but its suitability for prolonged immersion in specific chemicals should be confirmed by trial tests in the absence of applicable case histories. It is also suitable for underground exposure and as a protective coating for sound concrete surfaces in marine and some chemical environments. Its good weathering properties can be improved by applying a finish coat of a compatible aluminum pigmented paint. Although it is self-priming and exhibits good adhesion to clean structural steel surfaces, it may also be used over suitable inhibitive primers. The color of paint is black unless red is specified. (top)


Painting System Guide No. 12.00: Guide to Zinc-Rich Coating Systems

This guide provides general information on the description, selection and applications of zinc-rich coatings, and the selection of topcoats. Zinc-rich coatings are highly pigmented primer coatings that are uniquely defined by their capability of galvanically protecting steel exposed at discontinuities such as narrow scratches and holidays. While the major pigment component in a zinc-rich coating is zinc dust, the vehicle may be inorganic or organic. Zinc-rich coatings are classified as follows: Type IA--Inorganic - postcured, water-borne, alkali-silicates; Type IB--Inorganic - selfcured, water-borne, alkali-silicates; Type IC--Inorganic - selfcured, solvent-borne, alkyl-silicates; Type IIA--Organic - thermoplastic binders; Type IIB--Organic - thermoset binders. Certain zinc-rich coating systems are suitable for use in protecting steel surfaces either topcoated or untopcoated. Zinc-rich systems are not suitable for certain exposure conditions. (top)


Painting System Specification No. 12.01: One-Coat Zinc-Rich Painting System

This specification covers a one-coat zinc-rich painting system to be used on steel in mild to moderately severe environments. This system is suitable for use on parts or structures exposed in Environmental Zone 3B (chemical, neutral). It is not recommended for environments where corrosive contaminants will have a pH below 5 or above 9 or severely corrosive environments. The system is recommended as a durable shop primer or as a protective one-coat system for normal atmospheric weathering environments and certain immersion services. This specification does not pertain to weldable prefabrication zinc-rich primers which are applied at lower thicknesses (one mil [25 microns] or less). Further information regarding these and other zinc-rich primers can be found in SSPC-PS Guide 12.00, "Guide for Selecting Zinc-Rich Painting Systems." (top)

This guide covers one-coat shop painting systems for steel that will not be exposed to corrosive conditions for long periods. They are also suitable for steel encased in concrete in those cases where bonding of steel to concrete is not required. They can be used under fireproofing. These systems are suitable for use on parts or structures exposed in Environmental Zones 0 (encased in concrete or masonry, normally dry) and 1A (interior, normally dry).

(top)


Painting System Specification No. 15.00: Guide for Selecting Chlorinated Rubber Painting Systems

These specifications cover chlorinated rubber painting systems for blast cleaned or pickled steel. These coatings are not recommended for areas exposed to strong organic solvents, oxidating acids, or the areas where the surface temperature exceeds 165 F (74 C). Straight chain unsaturated acids, and fats and oils of animal or vegetable origin will cause softening and swelling of these coatings. These systems are suitable for use on parts or structures exposed in Environmental Zones 1A (interior, normally dry), 1B (exterior, normally dry), 2A (frequently wet by fresh water), 2B (frequently wet by salt water), 2C (fresh water immersion), 2D (salt water immersion), 3A (chemical, acidic), 3B (chemical, neutral), and 3C (chemical, alkaline).

In addition, the finish paint allows for a choice of colors. (top)


Painting System Guide No. 17.00: Guide for Selecting Urethane Painting Systems

This guide outlines urethane painting systems for structural steel surfaces. There are three types of urethane coatings covered by the guide. They are Types II, IV, and V, as classified by ASTM Standard D 16. These painting systems are suitable for use on parts or structures exposed in varied types of environments ranging from severely corrosive environments to mild atmospheric conditions.

Painting System Guide No. 19.00: Guide for Selecting Painting Systems for Ship Bottoms

This guide covers painting systems for ship bottoms from the keel to the light load line on steel ships. The area from the light load line to the deep load line, more commonly called the boottop area, may also be coated with these systems; however, SSPC-PS Guide 20.00 covers painting systems for this area. It should be noted that boottops are rarely used with today's commercial ships, and bottom systems may extend up to the deep load line. These coating systems may also be used for other floating or stationary structures exposed to or submerged in salt or brackish water. This would include barges, buoys, oceanographic installations, etc. (top)


Painting System Guide No. 20.00: Guide for Selecting Painting Systems for Boottoppings

This guide covers painting systems for the protection of the exterior boottop areas (the area from the light load line to the deep load line) of steel ships. It should be noted that boottops are rarely used with today's commercial ships and bottom systems may extend up to the deep load line. In general, the anti-corrosive and anti-fouling paints covered in SSPC-PS Guide 19.00 are applicable to boottop areas. (top)


Painting System Guide No. 21.00: Guide for Selecting Painting Systems for Topsides

This guide covers painting systems for the protection of the topside or exterior area of steel ships. This includes the area from the deep load line to the rail, more commonly called the freeboard, decks, and superstructure.

They also cover all above-water areas on ships such as deck equipment or machinery, booms, mast, and bulwarks. (top)


Painting System Guide No. 22.00:Guide for Selecting One-Coat Preconstruction or Prefabrication Painting Systems

This guide covers those shop primers used in today's modern commercial shipyards for preconstruction and prefabrication priming of abrasive blast cleaned structural steel and steel plates. To maximize efficiency in new construction, all ships' steel plates, shapes, and angles are abrasive blast cleaned, shop primed and stored for future use in preparation of sections of ships, called modules or units. Shop primers are covered by generic classification. (top)
