A Chromate Polyvinyl Butyral Two-Component Etching
Wash Primer. Widely used with aluminum roof coatings, metal roof
paint and infrastructure in harsh and marine environments. Promotes
adhesion on hard to paint substrates such as aluminum, galvanized
metals and magnesium prior to the application of aluminum roof paint
and primer systems. It is especially effective on hard-to-adhere to
surfaces such as aluminum and galvanized steel. It is not intended
as a permanent protective roof paint in itself although some
protection is afforded for short periods of time. To ensure best
results, the pre-treatment should be coated with metal roof paint as
soon as possible. Meets Federal Specification number MIL-P-15328.
Recommended application is by means of a light brush coat at a dry
film thickness of .00076 cm. to .00127 cm. Although, for best
adhesion results, this Primer should be applied by spray to no more
than a fog coat. It is not necessary to hide the substrate with the
primer. The major purpose of this primer is to provide an adhesion
surface for subsequent primers and protective roof paint. Color:
Green.
Stats: Covers 400-500 square feet per gallon. Dry to the touch in
5-10 minutes, tack free in 10 minutes, time to recoat 15-30 minutes.
Pot life: 2-3 hours. Low temperature curing (as low as 20 F.)
Catalyst Mixing Rate: 4: 1 Part A : B. Available in one gallon and
five gallon kits.
Recommended preparation: For best results remove old
metal roof paint, loose scale, grease, oil and contaminates. Sand,
grind, bead blast or power-wash prior to the application of any
cleaner or primer. Steel: TS-5679 Phos-Pro
Rust Converting Cleaner, etch concrete with
TS-695 Etching Cleaner. All surfaces must be thoroughly dry
before the application of any metal roof paint.
Thin
& clean up: Use only with factory recommended thinner, Thin with
Isopropyl Alcohol. Clean tools and equipment with alcohol,
TS-605 Synthetic Thinner or
TS-610 Lacquer Thinner.
