Klass Kote - epoxy paint data sheet

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

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 Reducer. If the recommended reducer is not available, use a high-grade lacquer thinner.

Application
Klass Kote products work ideally with conventional air-atomising spray equipment, as well as HVLP and airless equipment. (Can also be applied with a brush or roller). 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 inducted/react for 30 to 40 minutes, (with occasional stirring) prior to application Always mix equal parts 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 Reducer. If Klass Kote Reducer is unavailable, use a high-grade lacquer thinner formulated to reduce epoxies.

Cure schedule
For best results paint and surface should be over 70 degrees F. Klass Kote can be force dried after solvent has been flashed off. Suggest 12 to 15 minutes to speed cure time.
At 70 degrees F (air & substrate temperatures):

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.

Packaging
Available in pint (473ml) kits (2 x ½ pints (237ml)), quart (946ml) kits, (2 x pints) & ½ gallon (1893ml) kits, (2 x quarts). All applications require equal parts of epoxy (part-A) and catalyst (part-B).

Durability
Continued, prolonged, outside exposures to ultra-violet light may cause some degree of oxidisation (chalking) and/or induce slight color fading. Normal periods of exposure will not affect the film. In most conditions, Klass Kote will retain its outstanding protective integrity.

 

Klass Kote - epoxy primer data sheet

Description
Klass Kote Grey Primer #50 & White Primer #55 are high solids, catalysed, sand-able primers with excellent filling and rust-inhibiting capabilities. They have been extensively field tested since 1964. Grey Primer #50 contains Zinc Chromate pigment as the anti-corrosive agent, while White Primer #55 contains Zinc Phosphate. On the ASTM B-117 test for rust creepage away from x-scribe on steel panel, Grey Primer #50 rated 10 on a scale of 0-10. (0-worst, 10-best), while White Primer #55 rated a 9.
These products are designed to be the first primer applied to bare substrates. White Primer #55 must be catalysed with Klass Kote Primer Catalyst White Fast #420, while Grey Primer #50 can be catalysed with either Primer Catalyst White Fast #420, or Primer Catalyst #415 – based on cure schedule requirements and shop conditions.

Basic uses
Rust-inhibiting, sand-able protective primer.

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 Reducer #500. If the recommended reducer is not available, use a high-grade lacquer thinner. For rusted, heavily scaled or previously painted surfaces, sanding to bare surface or media blasting is recommended. If this is not practical, use other conventional methods to remove scale and old paint/primer. IT IS NOT RECOMMENDED TO USE Klass Kote EPOXY PRIMERS OVER OLD PAINT OR UNCATALYSED PRIMERS!

Application
Klass Kote products work ideally with conventional air-atomising spray equipment, as well as HVLP and airless equipment. (Can also be applied with a brush or roller.) Once the components are mixed and reduced, Klass Kote covers like most conventional primer coats. For best results while using conventional spray equipment with Grey Primer #50 & Primer Catalyst #415, components parts A & B should be inducted or reacted for 30 to 40 minutes (with occasional stirring) prior to application. No induction is necessary when using Primer Catalyst White Fast #420. Film thickness should be built up by applying successive thin coats of primer 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. If using Grey Primer #50 with Primer Catalyst #415 allow mixture to inducted/react for 30 to 40 minutes, (with occasional stirring) prior to thinning and application. Always mix equal parts 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. Start with 6 parts paint to 1 part reducer. If Klass Kote Reducer #500 is unavailable, use a high grade lacquer thinner formulated to reduce epoxies. Do NOT over-reduce.

Technique
A film of the combined components A & B would yield a dry film by volume of (40.33 + 41.28) / 2 = 40.80. In other words, a wet film of 3 mils (.003) would yield a dry film of 3 x .048 = 1.22 mils.
Care must be taken in finish coating over epoxy primers. If film has not cured sufficiently, the catalyst component may migrate into the finish coat producing a cheese-like result. For rush jobs, induct parts A & B for 2-3 hours before applying, and/or use Primer Catalyst White Fast #420, with no induction necessary. This will cut the cure rate to approximately half the time.
Top coats must be applied no sooner than 12 hours after last prime coat, and no later than 36 hours, otherwise primer coat must be scuffed prior to top coating - (when using Primer Catalyst #415) With Primer Catalyst White Fast #420, top coating can occur in the range of 6-18 hours.

Cure schedule
For best results paint and surface should be over 70 degrees F. Can be force dried after solvent has been flashed off. Suggest 120°F for 15 minutes to speed cure time. At 70 degrees F (air & substrate temperatures):

Coverage
Using conventional air atomising spray equipment on a non-porous substrate, 1 quart of reduced Klass Kote will cover approximately 50-75 square feet. On more porous substrates, 1 quart will cover approximately 40-50 square feet.

Packaging
Available in pint kits (2 x ½ pints), quart kits, (2 x pints) & ½ gallon kits, (2 x quarts). All applications require equal parts of epoxy (part-A) and catalyst (part-B). For industrial customers, or jobs that require larger quantities, please email admin@baronpaints.co.uk.
