YELLOW SNOW PLOW BLADE PAINT

 

GENERAL DESCRIPTION

 

Pruett-Schaffer’s #20-14 Yellow Paint is a VOC compliant, water based acrylic emulsion paint.  It is designed as a low-gloss, dip applied, fast drying direct-to-metal coating for corrosion protection of metals.  The cured film exhibits very good flexibility, salt, and chemical resistance.  This coating provides a .8-1.4 mil thick dry film that can  be applied in one economical coat when used as supplied. It does contain nontoxic corrosion inhibiting pigment.

 

RECOMMENDED USES

 

This product is recommended for use on clean steel. It exhibits exceptional adhesion to a wide variety of substrates including minimally prepared cold rolled steel, galvanized steel, existing coatings, masonry, and even aluminum without pretreatment. Not recommended for immersion service or for areas subject to continual solvent splash.

 

SURFACE PREPARATION

 

For severe service, metal substrates should be blasted to SSPC-SP-6 minimum, with a 1 mil blast profile.  This coating is very forgiving of less than perfect surface preparation, so hand tool cleaning may be sufficient for some uses.  At a minimum for acceptable performance, surfaces to be coated must be clean, dry and free of oil/grease, loose rust/paint, weld spatter, burning slag, dust, and chalk.  Feather all rough or sharp edges.  Alkyd type paints should be deglossed before being recoated.  Chalky or dusty surfaces should be power washed and allowed to dry completely.

 

THINNING

 

Under normal conditions no thinning is necessary or desirable.  Thin if necessary with water only. Do not use organic solvents or oils.  Add water a little at a time with constant gentle agitation to a maximum of 5% by volume.

 

APPLICATION EQUIPMENT

 

May be applied by dipping, flow coat, brush, roller, or spray. Dipping is the preferred method of application. Dip tanks must be monitored for proper pH range to prevent flash rusting. Maintain pH between 8.8 and 9.6. Use roller covers with 3/8 to 1/4 - inch nap.  Brushes should be of polyester or nylon construction. This product may be used with a cup type spray gun. 

 

DRYING TIME

 

Dries to recoat in ˝ hour to 1 hour at 77 0F and 50% Relative Humidity.  High humidity will prolong dry time more so than low temperatures.  To speed the dry time good air movement over the work and local exhaust is recommended.  Heat lamps may be suitable for use but care must be exercised in heating too quickly, this may tend to trap solvent within the paint film causing water sensitivity.

 

CLEANUP

 

Clean equipment with warm soap and water before the film dries.
