GENERAL
DESCRIPTION Pruett-Schaffer’s
#13-4 Gray Epoxy is a two component, polyamidoamine –cycloaliphaticamine
cured epoxy for use as a heavy duty maintenance top coat. It is designed as a gloss, brush or spray applied, corrosion
resistant, ferrous metal coating. It exhibits excellent adhesion over a wide
variety of substrates, and exceptional corrosion and chemical resistance. 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.
Suitable for topcoating with a wide variety of epoxy, urethane, vinyl,
or acrylic emulsion topcoats.
May also be used as
an encapsulation coating. This epoxy
will chalk, topcoating is necessary for long term weathering exposure. 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 #13-5-A with 1 part 13-B Hardener. Mix at slow speed to avoid entraining air
into the paint. Use at once, there is
no induction time. THINNING Thin
if necessary for spraying with xylol or toluol. 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 4.5-7 mils wet film
thickness to yield 3-5 mils dry film thickness. Application with a cup type spray gun is not recommended. CURE
TIMES & TEMPERATURES Cures
set-to-touch in 1-1.5 hours at 77 0F, and dry to handle in 2-4
hours. Topcoat within 3-48 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.
Recommended minimum application temperature is 40 0F.
Below 40 0F
use 13-W winter cure hardener. |
