STAINLESS STEEL WATER BASED  ACRYLIC PAINT

 

GENERAL DESCRIPTION

 

Pruett-Schaffer’s #25-37 Stainless Steel Paint is an air-drying, water based acrylic emulsion paint.  It is designed as a medium gloss, spray applied enamel for general use.  The cured film exhibits very good salt and chemical resistance.  The coating allows high film build without sags, and the desired dry film thickness can be applied in one coat.

 

RECOMMENDED USES

 

This product is recommended for general equipment and building maintenance. It exhibits exceptional adhesion to a wide variety of substrates including minimally prepared cold rolled steel, galvanized steel, masonry, brick, existing coatings, and even aluminum without pretreatment.  Use where long term exterior durability and flexibility is required. Not recommended for immersion service or for areas subject to continual solvent splash or fume.

 

SURFACE PREPARATION

 

Apply over primer for severe service (follow primer surface preparation instructions) or direct-to-substrate.  For severe service, substrates should be blasted to SSPC-SP-6, with a 1-mil blast profile.  Feather all rough or sharp edges.  This coating is very forgiving of less than perfect surface preparation however, so hand tool cleaning may be sufficient.  At a minimum for acceptable performance, all surfaces to be coated must be clean, dry, and free of oil/grease, loose rust/paint,

weld spatter, burning slag, dust, and chalk.  Degloss previously painted surfaces for best adhesion.

 

THINNING

 

Under normal conditions, no thinning is necessary or desirable .  Thin if necessary for spraying with water, 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 pressure pot or airless spray.  Brushes  or rollers will drag the stainless steel flake ruining the appearance.  Use a .015-.020 inch gun tip size for spraying. Do not apply with a cup-type spray gun.  Apply 4.5-7 mils wet film thickness to obtain the recommended dry film thickness of 2-3 mils per coat.  3-5 mils dry film total thickness is recommended for best performance.

 

DRYING TIME

 

Dries to recoat in 1 to 1.5 hours 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 are not suitable as they tend to trap solvent within the paint film causing water sensitivity.

 

 

 

 

CLEANUP

 

Clean equipment with warm soap and

water before the film dries.  Run ethyl alcohol through spray guns after cleaning to prevent corrosion of steel parts.

 

ENVIRONMENTAL

 

This product meets current air pollution regulations regarding hydrocarbon and ozone reactive emissions.  It contains no lead or chromate.
