|Publication Date:||30 April 2014|
This specification covers the requirements for a two component, high solids epoxy coating with a maximum volatile organic compound (VOC) content of 340 grams/liter (g/l) (2.8 pounds/gallon (lbs/gal)). This coating is lead and chromate free. The coating is supplied as a kit.
Classification. The coatings are of the following types, classes and grades, as specified.
Types. The coating will be furnished in the following types as specified.
Type II - Volatile organic hazardous air pollutants-free (VOHAP-free) formulation to meet maximum VOC content of 340 g/l (2.8 lbs/gal) as packaged. The type II is a direct replacement for the type I, which has been cancelled.
Type III - Direct to metal, VOHAP-free formulation to meet maximum VOC content of 340 g/l (2.8 lbs/gal) as packaged. As a direct to metal, this coating will have enhanced corrosion performance including 1,000 hours salt spray and 40 cycles on the cyclic corrosion test. This type is only available in semi-gloss and lusterless colors.
Type IV - Self contained portable kits.

This epoxy coating is intended for use as an interior topcoat on aircraft and ground support equipment, as well as a repair coating on Navy weapon systems. No additives other than the appropriate thinner to obtain the proper spray viscosity are to be added. This coating contains a maximum VOC of 340 g/l (2.8 lbs/gal) and is lead and chromate free. The type II and III formulations are VOHAP-free. The type III formulations are designed as direct to metal with an enhanced corrosion performance of 1,000 hour salt spray and 40 cycle corrosion resistance. The grade B coating is for interior use only.View Less
