ALUMINUM QUICK DRY ENAMEL

 

GENERAL DESCRIPTION

 

Pruett-Schaffer’s #34-62 Aluminum Enamel is an semi gloss, fast air drying, solvent based alkyd paint.  It is designed as a brush or spray applied, finish coat for use over primer.  It exhibits good flexibility, corrosion resistance, exterior durability, and heat resistance to 250 °F.

 

RECOMMENDED USES

 

This product is recommended for general maintenance use on railcars, storage tanks, machinery, and other steel equipment wherever a good quality alkyd finish is needed. It exhibits exceptional adhesion to a wide variety of substrates including minimally prepared cold rolled steel, forgings, castings, and existing coatings. This coating is specially recommended for use over rough surfaces or where extensive surface preparation will not be performed, as the semi gloss finish of this paint will hide many of the surface defects that would be readily apparent with a high gloss paint.  Not recommended for immersion service, for areas subject to severe chemical exposure or heat greater than 300 °F.

 

SURFACE PREPARATION

 

For severe service, metal substrates should be blasted to SSPC-SP-6 minimum, with a 1 mil blast profile, and primed with a good quality alkyd primer (such as Pruett-Schaffer #30-12620).  This coating is very tolerant 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 and dry, and free of oil/grease, loose rust/paint, weld spatter, burning slag, dust, and chalk.  Feather all rough or sharp edges.  Chalky or dusty surfaces should be power washed and allowed to dry completely.

 

THINNING

 

Under normal conditions no thinning is necessary.  Thin if necessary for spraying with xylol or toluol.  Add a little at a time with constant gentle agitation to a maximum of 5% by volume.  In ambient temperatures over 85 0F Aromatic 100 or Aromatic 150 may be used if “dry spraying” occurs.

 

APPLICATION EQUIPMENT

 

May be applied by brush or airless spray.  Airless spray gives the best results, use .015-.020 inch tip size.  Brushes should be of polyester or nylon construction.  If applying with a cup type spray gun, thinning may improve application.  Apply to 2-3 mils dry film thickness maximum.

 

DRYING TIME

 

Dries to recoat or stencil in 3 to 4 hours at 77 0F.  Dry to light handling in 24 hours.  Force drying ovens may be used, allow 30 minutes minimum for flashoff of solvent before heating.

 

CLEANUP

 

Clean equipment with xylol or toluol before the film dries.
