GENERAL
DESCRIPTION Pruett-Schaffer’s
#16-13057 White Epoxy is a two
component, polyamide cured epoxy for use where good chemical resistance is
needed. It is designed as a high
gloss, spray applied, corrosion resistant, heavy duty, topcoat. It
exhibits excellent adhesion over a wide variety of substrates, and
exceptional corrosion, water and
chemical resistance. All components
of this product are approved by the FDA for incidental contact with
foodstuffs. RECOMMENDED
USES Use
to protect machinery, tanks, and structures from corrosion in aggressive
environments where chemicals, salt, water, fuels, and oils are present. Formulated to allow high film build in one
pass to protect hard to cover sharp edges. May also be used as an
encapsulation coating. This formula
will chalk on long term exposure to sunlight. SURFACE
PREPARATION For
severe service, metal substrates should be blasted to an SSPC-SP-10 white
metal blast with a 1.5 +/- .5 mil blast profile. An SP-6 commercial blast may be sufficient for many repair or
DTM applications with less severe requirements. This coating is very tolerant of poor surface preparation; for
tightly adhering existing coatings, degreasing and hand tool cleaning, power
washing, brush blasting, sanding, or a combination of these methods may be
acceptable. All surfaces to be coated
must be clean, dry, and free of oil and grease, loose rust and paint, weld
spatter, |
burning
slag, dust, and chalk. MIXING
INSTRUCTIONS Mix
4 parts by volume #16-13057-FDA with 1 part 16-FDA Hardener. Mix at
slow speed to avoid entraining air into the paint. Do not reuse previously used mixing
containers; partially cured material will greatly accelerate the cure of the
freshly mixed paint resulting in dramatically reduced pot life. THINNING Thin
if necessary for spraying with xylol (or Acetone to maintain VOC). Add a little solvent at a time to the
mixed system with constant gentle agitation to a maximum of 5% by volume. APPLICATION
EQUIPMENT May
be applied by air-assisted or airless spray.
Airless spray gives the best results, use .015-.020 inch tip
size. Apply 5.5 to 7.5 mils wet film
thickness to yield 3-4 mils dry film thickness. Brushes should be of polyester or nylon construction if used. CURE
TIMES & TEMPERATURES Cures
set-to-touch in 1 hours at 77 0F, approximately 2 hours at 70 0F.
If thicker films are desired retopcoat within 8-48 hours or reduced
adhesion of the second coat may result.
Allow 7-10 days cure at 70 0F before placing into severe service,
longer if ambient temperature is lower. |
CLEANUP Clean
equipment with xylol or toluol before the film cures. ENVIRONMENTAL This
product meets current air pollution regulations regarding hydrocarbon and
ozone reactive emissions. It is VOC
compliant for the architectural maintenance industry, and contains no lead,
chromate, or zinc. PHYSICAL
