GENERAL
DESCRIPTION Pruett-Schaffer’s
#30-48 Red Oxide Primer is a fast drying, solvent based, oil &
hydrocarbon resin modified alkyd paint.
It is designed as a brush or spray applied, corrosion preventative
metal primer. It is a cost effective
general use primer, having good application properties, exterior durability,
and adhesion and water resistance. RECOMMENDED
USES This
product is recommended for general maintenance use on railcars, storage
tanks, machinery, and other steel equipment wherever a good quality alkyd
primer is needed. It exhibits exceptional adhesion to a wide variety of
substrates including minimally prepared cold rolled steel, forgings, castings,
and existing coatings. This primer is specially recommended for use over
surfaces where extensive preparation will not be performed, as the long oil
length alkyd formulation of this paint wets rusty and oily substrates
efficiently and develops good adhesion.
May be used as a primer or tie coat suitable for overcoating with
water or solvent based alkyds. The in
service temperature limit is approximately 350 0F. This
product is not recommended for immersion service, for areas subject to severe
chemical exposure, or for use over wood.
A test patch to determine compatibility is recommended before
topcoating with solvent based acrylic, vinyl, epoxy, or urethane coatings as
the active oxygenated solvents sometimes present in these coatings may cause
newly applied primer to blister or disbond. |
SURFACE
PREPARATION For
best results, substrates should be blasted to SSPC-SP-6 commercial blast with a 1 mil profile, and all rough areas
and sharp edges smoothed. This
coating is tolerant of less than perfect surface preparation however, and
hand or power tool preparation such as brushing, sanding or water blasting
may be sufficient for many applications.
At a minimum for acceptable performance, surfaces to be coated must be
clean, dry, free of heavy oil and grease, loose rust and paint, weld spatter,
burning slag, dust, and chalk. THINNING Under
normal conditions no thinning is necessary; if required for proper spraying
thin 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 equipment. Airless spray gives the best results, use .015-.020 inch tip
size. Brushes should be of polyester
or nylon construction. Apply to
1.8-5.5 mils wet film thickness, which yields 1.0-3 mils dry film. DRYING
TIME Dries
set to touch in 10-20 minutes, dry to light handling in 30 minutes to 1 hour,
dry to recoat in 2 hours at 77 0F. Force drying ovens
may be used, allow 15 minutes minimum for flashoff of solvent before heating. |
CLEANUP Clean
equipment with xylol or toluol before the film dries. ENVIRONMENTAL This
product meets current air pollution regulations regarding hydrocarbon and
ozone reactive emissions. It is VOC
compliant for the railcar and architectural maintenance industries, and
contains no lead, or chromate. Read
and understand Material Safety Data Sheet for this product before using. PHYSICAL
