(Solvent Type)

The General Services Administration has authorized the use of this

Commercial Item Description by all Federal Agencies in lieu of

Federal Specification MMM-A-105

1.0 SCOPE. This Commercial Item Description covers high viscosity, fast drying, one part adhesive intended for bonding a range of porous and non-porous materials such as ceramics, marble, marble, glass, metal, leather, fabric and paper labels. This material may also be used for waterproofing. The product shall be a uniform solution or homogeneous dispersion of cellulose nitrate and plasticizers in low boiling solvent(s).

2.0 SALIENT CHARACTERISTICS

2.1 Polymer type. The adhesive polymer shall consist of cellulose nitrate dissolved in an EPA exempt VOC solvent.

An infrared spectrogram of adhesive solids shall be compared to a known cellulose nitrate spectrogram from the Sadtler series (or similar) of standard spectra. All major absorbance wavelengths shall match or the product fails.

2.2 Resin solids. The minimum cellulose nitrate resin solids shall be 25.0% on the oven dry weight basis when tested in accordance with ASTM D-1259 (Method A).

2.3 Volatile Organic Content (VOC). The maximum allowable VOC shall be 680 grams per liter when test in accordance with ASTM D 3960.

2.4 Viscosity. The adhesive viscosity shall be within the range of 65-90 poises at 20-23^oC, when tested in accordance with ASTM D 2196 (Method A).

2.5 Color. The liquid adhesive color shall be clear with no visual color tint through a 10.0 cm (3.9 inch) visual path length.
