MODERN MASTERS MASTERCLEAR SEMIGLOSS CLEAR TOPCOATS are especially formulated as non-yellowing topcoats for Modern Masters Metallic Paint Collection paints to help protect and preserve the color and shimmer of the Metallic Paints when applied to either interior or exterior surfaces. The aliphatic nature of the polyurethane-acrylic copolymer when combined with the UV absorbers and inhibitors provides the highest resistance possible to damaging ultra-violet radiation. The inherent high abrasion resistance of the aliphatic polyurethane-acrylic copolymer also extends the service life of MasterClear Clear Topcoats. MasterClear Semigloss (ME662) is particularly
suited for the higher-gloss colors of the Metallic Paint Collection paints.

PRODUCT DESCRIPTION:
Modern Masters MasterClear Semigloss Interior/Exterior Clear Topcoats are
translucent water-based liquid dispersions of a self-crosslinking (no activator needed) aliphatic (non-yellowing) polyurethane-acrylic copolymer. MasterClear Clear Topcoats are formulated with UV absorbers and inhibitors, mar and slip aids, wetting and rheology modifying agents to create the best possible protection for Metallic Paint Collection paints.

SURFACE PREPARATION:
Before applying MasterClear Clear Topcoats, the previously coated surface must be completely clean, dry, and fully cured. Remember that MasterClear Clear Topcoats will not conceal any surface blemishes or imperfections, so carefully prepare the surface beforehand. If applying MasterClear Clear Topcoats over something other than Metallic Paint Collection paints, test a small sample area to ensure the desired results.

APPLICATION:
Modern Masters MasterClear Clear Topcoats can be brush, roll, or spray applied. For best protection, apply a minimum of two coats for interior applications and a minimum of three coats for exterior applications. Allow two hours between coats and a minimum of 24 hours for full cure before use. For best results, do not apply in temperatures below 50°F (10°C) or in humidities above 50%RH. Lower temperatures and higher humidities will lengthen the dry and cure times. Stir before use; do not shake.

Brushing: Use a use a high-quality synthetic bristle brush recommended for water-based semigloss paints.

Rolling: Use a high-quality short nap varnish roller.

Spraying: Use an HVLP spray gun in combination with an air compressor. Important.Note: Do not use turbine-type “air compressors” to power the HVLP spray gun; do not use other types of spray guns (e.g. airless spray guns). Air pressure at the HVLP spray gun needs to be approximately 65 psi, with greater pressures in the tank. Thinning is not usually required; however, MasterClear Clear Topcoats may be thinned for spraying by adding up to 10% water by volume. Thin carefully, as over thinning of the paint may result in a loss of rheology and a reduction of the desired protection. When spraying, be sure to use a properly fitting NIOSH approved breathing mask.

Coverage: One gallon will cover approximately 300 to 400 square feet.

FILM PROPERTIES:

Dry film: Non-yellowing, semi-gloss or satin finishes.

Scrub Resistance: Passes approximately 3000 cycles per ASTM D4213.

Gloss Levels: ME662, MasterClear Semigloss, approximately 65 at 60°.

Drying time at 70°F and 50%RH: Dry-to-touch is in approximately ½ hour. Re-coat time is in approximately two hours. Full cure is in approximately 24 hours. Lower temperature and higher humidity will lengthen the dry and cure times.
