GENERAL
DESCRIPTION Pruett-Schaffer’s
#18-2 Yellow Epoxy Lining is a high performance, two component epoxy for use
as a steel or concrete protective coating or lining. This coating is
formulated with state-of-the-art bisphenol F epoxy resins and a blend of
aliphatic and cycloaliphatic amine hardeners to provide maximum protection in
severe exposures. It exhibits good exterior durability (but will chalk), very
good adhesion over a variety of substrates, and exceptional corrosion and
chemical resistance. RECOMMENDED
USES This
material is designed as a flow coated or fill & drain direct-to-metal lining for pumps. Use to protect machinery, tanks, and
structures from corrosion in aggressive environments where chemicals, salt,
water, fuels, and oils are present.
Formulated with virtually no solvent, this coating will flow out
leaving a dry film build of 10-20 mils, providing excellent protection over
hard-to-cover sharp edges and complex geometric shapes. SURFACE
PREPARATION For
severe service, application over primer is recommended (Pruett-Schaffer
#18-13275 Yellow Oxide Epoxy Primer or equivalent). Metal substrates should
be blasted to an SSPC-SP-10 white metal blast with a 1.5 to 2.0 mil blast
profile. A 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
new or 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 or paint, weld
spatter, burning slag, dust, and chalk. MIXING
AND POT LIFE The
recommended minimum application temperature is 50 0F. Mix 4 parts by volume #18-2-A with
1 parts 18-2-B Hardener. May be used immediately, but a 5-15 minute induction
time will give "Blush Free" results. Because
of the relatively short pot-life this may not be practical. Pot life when mixed in 4-gallon lots: is
30-45 minutes at 77 0F. Store mixed material in a cool water bath
to prolong pot-life. Do not reuse previously used mixing containers;
partially cured material will greatly accelerate the cure of freshly mixed
paint resulting in dramatically reduced pot life THINNING
AND CLEANUP Thin
and cleanup equipment with xylol.
Thin only when necessary; add a little solvent at a time to the mixed
system with constant gentle agitation to a maximum of 5% by volume. APPLICATION
EQUIPMENT No
application equipment is required. This product is meant to be applied by
flow coating or filling reservoirs & subsequently draining them. |
CURE
TIMES & TEMPERATURES Cures
tack free in 4-6 hours at 77 0F.
Will cure down to 50 0F, but curing time will appreciably
lengthen below 60 0F. Allow 3-7 days cure at 70 0F before placing into severe service,
longer if the ambient temperature is lower than 60 0F. ENVIRONMENTAL This
product meets current air pollution regulations regarding hydrocarbon and
ozone reactive emissions. It is VOC
compliant for the architectural maintenance industry, contains no chromate or
zinc, and complies with current federal regulations regarding the use of lead
in paint. PHYSICAL
