COMMERCIAL ITEM DESCRIPTION
PAINT, STENCIL
(AEROSOL)
The General Services Administration has authorized the use of this commercial item description in preference to Federal Specification TT-P-98.
Salient characteristics:
The aerosol stencil paint covered by this description is intended for spraying on bales, crates, boxes, and drums. It shall be formulated to obtain maximum color stability and minimum chalking tendencies to allow for exterior as well as interior use. The paint shall be packaged in a nominal 16-ounce commercial pressurized dispenser with a minimum solids content of 54g ( except black which will have a solids content of 40g). The paint, at room temperature, shall be dispersible by hand shaking for 1 minute. The valve shall spray easily with moderate finger pressure and close immediately upon release of finger pressure. The spray shall be without sputtering or interruption, and a smooth and uniform film shall be deposited. The can shall deliver at least 98 percent by weight of the contents.
Drying time. The paint shall set to touch in 15 minutes and dry hard in 1 hour (ASTM D 1640).
Color*. The paint shall be a general match to the specified color chip (ASTM D 1729).
Specular gloss*. The 60o specular gloss shall be a maximum of 30 percent (ASTM D 523).
Hiding power. Complete wet and dry hiding shall be obtained with a dry film thickness no greater than 50um. Test by spraying over a leneta spray monitor until complete wet hiding is obtained. Allow to dry for 4 hours, evaluate the dry hiding and then determine the dry film thickness.
Flexibility*. The paint shall allow no cracking or flaking when bent over a ¼ -inch mandrel (ASTM D 1737)
Cohesion*. The paint shall ribbon or curl without flaking or powdering and show beveled edges at a cut made with a curved blade craftman’s knife held at a angle of 30o from the film.
Adhesion *. No more than 5 percent of the film shall be affected when tape is pulled from the scored film (minimum rating of 4B under ASTM D 3359, method B).
Chemical resistance*. There shall be no softening, blistering, wrinkling, loss of adhesion or color change when immersed separately in the following chemicals for the corresponding times, wiped clean, allowed to recover for 2 hours and then tested for film integrity by lightly scraping with a metal spatula (ASTM D 1308):
Water (25 + 5o C) for 18 hours
Lighter fluid (25 + 5o C) for 10 minutes
3-in-1 oil (110 to 115o C) for 2 hours
*The test panels shall be prepared from type 3 steel in accordance with ASTM D 609, method D. Spray a film which will dry to a thickness of 50 + 5um and allow to cure for 5 days at standard conditions before testing.
The issues of ASTM standards in effect on the date of the solicitation shal be used to determine compliance with these requirements.
Certification. The contractor shall certify that the product offered meets the salient characteristics of this description, and that the product conforms to the producer’s own drawings, specifications, standards, and quality assurance practices, and is the same product sold in the commercial marketplace. The Government reserves the right to require proof of such conformance prior to first delivery and thereafter as maybe otherwise provided for under the provisions of the contract.
Regulatory requirements. The manufacturer shall utilize recovered materials to the maximum extent practicable.
