scope:

This specification establishes the performance requirements for weather-resistant coating systems for use on primed, smooth metal, glass reinforced plastic (GRP), wood and plastic/composite exterior surfaces.

Classification. Coatings are of the following types, classes, and grades, as specified (see 6.1 and 6.2).

Types.

Type II - Standard durability coatings with Volatile Organic Compound (VOC) Content not greater than 340 grams per liter (g/L) [2.8 pounds per gallon (lb/gal)] (Colors restricted to non-gray marking or striping colors.)

Type III - Standard durability coatings with VOC not greater than 250 g/L (2.08 lb/gal)

Type IV - Standard durability coatings with VOC not greater than 100 g/L (0.83 lb/gal)

Type V - High durability coatings with VOC not greater than 250 g/L (2.08 lb/gal)

Type VI - High durability coatings with VOC not greater than 100 g/L (0.83 lb/gal)

Class.

Class 1 - High gloss,≥85

Class 2 - Semi-gloss, 45 to 60

Class 3 - Low gloss, 7 to 12 1.2.3

Grade.

Grade A - Standard pigmented

Grade B - Low solar absorbent (26173, 26270, 26373, and 26008)

Grade C - Low solar absorbent and anti-stain (26008 and 26270)

Composition.

Composition 1 - One component

Composition 2 - Two component

intended Use:

This specification covers high grade coatings intended for use on exterior topside surfaces that are highly weather-resistant and characterized by excellent color and gloss retention, good drying,... View More
