EPOXY VARNISH


EV-400 EPOXY VARNISH

Use:

EV-400 Epoxy Varnish is a two-part varnish that gives superior protection and performance over older one-part "spar" varnishes. EV-400 is completely impervious to fabric cements and dope when cured, so there is no need to use a dope proof paint over it. Epoxy varnish may be used on either old or new wood. It can be brushed or sprayed and is applied without harm directly over old varnishes to provide superior solvent resistance and protection from fabric cements and dopes.

Packaging:

Each component (Varnish, EV-410 Catalyst, and E-500 Thinner) is sold individually or as a kit.

Gallon Kit: 1 gallon EV-400 Varnish, two quarts EV-410 Catalyst, one gallon E-500 Epoxy Reducer. Yield: 2 gallons when all components are mixed.

Quart Kit: 1 quart EV-400 Varnish, one pint EV-410 Catalyst, one quart E-500 Epoxy Reducer. Yield: 2 quarts when all components are mixed.

Coverage: One gallon of catalyzed and reduced varnish will cover 600 sq. feet with one coat.

Mixing and Thinning:

Add exactly one part EV-410 catalyst to two parts EV-400 Varnish. Measuring must be accurate for proper drying. Stir thoroughly and wait 20 minutes induction time before using.

  • Thin two parts catalyzed varnish with one part E-500 Epoxy Thinner.
  • Application:

    EV-400 Epoxy Varnish may be brushed or sprayed. The first coat on new wood should be brushed; the remaining coats should be sprayed. Spray with equipment rated for lacquers or enamels. Spray three coats, at least 20 minutes apart allowing the surface to become tacky between coats. Final film thickness should be 1 to 2 mils when dried. Flooding on coats will result in crawling or cratering.

    Dry/Cure Time:

    Epoxy Primer will dry to the touch in 30 to 60 minutes in most conditions. However, it takes a full seven days at 70 degrees to chemically cross-link to a full solvent resistance. So in simplest terms, if you rush applying fabric cement or dopes over the top of varnish that has not cured for seven days, you risk wrinkling the varnish. This is most probable in the early hours following varnish application. As time passes in the seven-day cross linking period, the primer gets more solvent resistant and the possibility of wrinkling decreases.

    Pot life:

    The sooner applied after induction, the better the service life durability. Maximum pot life seven hours at 70 degrees. Discard mixed primer when it increases viscosity or becomes stringy. Do not add reducer to "save" varnish that has become viscous or is beginning to harden.

    Clean up:

    Use E-500. MEK may be substituted but may not clean tools and spray guns as well as E-500. Do not allow varnish to dry in the gun, it will be almost impossible to remove.

    Shelf life:

    Guaranteed shelf life unopened is four years from date of manufacture. Avoid storage above 100 degrees F.
