This specification covers a quick drying zinc dust, zinc oxide, and phenolic varnish paint for steel or galvanized surfaces. It has very good rust inhibitive characteristics, but only fair wetting ability for rusting, greasy, or oily surfaces. It has a drying time of about 12 hours, good durability even when weathered before finish coating and may be used for intermediate and finish coats.
This paint is supplied in two-package kits: one package contains the liquid vehicle (Component A); the other package contains the zinc dust-zinc oxide pigment (Component B).
This paint is suitable for exposure in Environmental Zones 1A (interior, normally dry) and 1B (exterior, normally dry), and is particularly suited for exposure in Environmental Zone 2A (frequently wet by fresh water). It is intended for brush or spray application over steel surfaces prepared in accordance with SSPC-SP 6, “Commercial Blast Cleaning;” SSPC-SP 10, “Near-White Blast Cleaning;” SSPC-SP 5,“White Metal Blast Cleaning;” and SSPC-SP 8, “Pickling;” or over clean galvanized steel.
This paint is suitable as a shop primer, field primer, maintenance primer, or intermediate coat and is to be applied in accordance with SSPC-PA 1, “Shop, Field, and Maintenance Painting of Steel.” This paint will dry in about 12 hours and should be recoated within 24 hours for optimum intercoat adhesion.
The good weathering ability of this primer is the result of its phenolic varnish vehicle.
This paint contains approximately 60% by volume of nonvolatile film-forming solids (pigment and binder). The theoretical spreading rate for a 2.0 mils (51 micrometers) dry film thickness is 480 square feet/U.S. gallon (11.8 square meters/liter). Actual spreading rates can be significantly lower.
