DESCRIPTION
KLASS KOTE is a series of two-component epoxy coatings available in a
variety of colors, primers, and clear. It is quick air-drying, chemical
hardening, and thermosetting. It can be forced dried to accelerate
cure. The dried film is very attractive, tough, durable, as well as
flexible. It provides excellent adhesion on a wide variety of substrate.
BASIC USES
KLASS KOTE has been field tested since 1964 on many different substrates
including steel, aluminum, masonry, wood, wood composition boards and
several other substrates.
PHYSICAL DATA
Note *** (based on White #100 with Gloss Catalyst #405)
SOLIDS BY WEIGHT 56.23%
SOLIDS BY VOLUME 44.94%
SURFACE PREPARATION
The surface must be clean and free from dirt, dust, grease, rust, and
scale, or anything that will otherwise impede adhesion. Whenever
possible, solvent wash with KLASS KOTE EPOXY REDUCER #500. If the
recommended reducer is not available, use a high-grade lacquer thinner.
APPLICATION
KLASS KOTE products work ideally with conventional air-atomizing spray
equipment, as well as HVLP and airless equipment, and can also be
applied with a brush or roller. If you choose to apply Klass Kote Epoxy
with a brush - choose a high-quality, natural bristle brush. Once the
components are mixed and reduced, KLASS KOTE covers like most
conventional finish coats. Film thickness should be built up by applying
successive thin coats of paint and allowing about 20 minutes "flash
off" time between coats.
For electrostatic application, if conductivity does not fall within the
prescribed range for a given application the conductivity can be raised
by adding a polar solvent, such as PPG DTL 16 or Klean-Strip L-27. The
polar solvent may have to be added a number of different times in a
number of different quantities before desired conductivity is reached,
so be sure to record the amount added to each test batch before
application.
MIXING INSTRUCTIONS
Thoroughly mix equal parts by volume of components A & B. Allow
mixture to induct/react for 30 to 40 minutes, (with occasional stirring)
prior to application. Always mix equal parts by volume of epoxy and
catalyst components together first --before reducing the mixture. The
amount of reducer needed depends upon ambient temperature and type of
spray equipment used. For finish coat, start with 6 parts paint to 1
part KLASS KOTE EPOXY REDUCER #500. If KLASS KOTE REDUCER is
unavailable, use a high-grade lacquer thinner formulated to reduce
epoxies. Reduction up to 1-to-1-to-1 (1-part A, 1-part-B, & 1-part
Reducer) may be necessary to achieve the proper viscosity -- especially
when working with smaller guns and air brushes. Do NOT over-reduce!
CURE SCHEDULE
For best results paint and surface should be over 70° F. Klass Kote
Epoxy can be force dried after the solvent has been flashed off. Suggest
120°F for 15 minutes to speed cure time.
At 70°F (air & substrate temperatures):
TACK FREE TIME: 20-30 MINUTES
PRINT FREE TIME: 4 HOURS
PACKAGING TIME: 24 HOURS
RECOAT WINDOW: 1 – 24 HOURS (DEPENDING ON SHOP
CONDITIONS)
SWARD HARDNESS: 4 DAYS - 1 WEEK
COVERAGE
Using conventional air atomizing spray equipment on a non-porous
substrate, 1 quart of reduced KLASS KOTE will cover approximately 75-100
square feet. On more porous substrates, 1 quart will cover
approximately 60 square feet.
Note this paint must go UPS ground.
