One of 3 options for the finishing colour coats of the Poly-Fiber system.
A durable, one-part, air-drying, flexible coating available in 50 popular aircraft colors. Poly-Tone is considered to be our “standard” pigmented finish for the Poly-Fiber covering process.
Poly-Tone is non shrinking, non bleeding, fire retardant, chemical resistant, and is used mostly on fabric but can be applied to metal and fibreglass using certain processes.
Poly-Tone generally has a satin (silk) finish in appearance once applied and fully dry. However there are methods to improve the gloss level of the final finish. It can be polished to a high luster equal in appearance to any cellulose dope, lacquer, or synthetic enamel finish.
Out of our 3 options, Poly-Tone is the most compatible with the previous coats in terms of a physical and chemical bond. The thermo-expansion and elasticity is the same as all of the sub-coats.
It is the most flexible top coat, the easiest to repair (by far), the easiest to apply, and for those who are weight-critical, it’s the lightest.
PolyTone may be sprayed with any equipment rated for lacquer and enamel. Clean the equipment with Poly-Fiber Reducer or Methyl Ethyl Ketone.
One gallon of PolyTone will cover approximately 200 sq. ft. with one coat.
Dust free in 20 minutes. Allow 12 hours drying before using masking tape. All drying times are given at 70° F and 50% relative humidity. Adding Blush Retarder will slow drying time and improve the gloss.
Poly-Tone is always thinned 4 to 1 with Poly-Fiber Reducer R 65-75 in normal 65°-75° weather, or RR 8500 Retarder Reducer in temperatures of 85° and up. Add Blush Retarder BR-8600 as needed in hot humid weather. Using any other reducer or retarder may cause adverse characteristics.
Finishing Metal Surfaces
We recommend stripping any old finish and re-priming with EP-420 Epoxy Primer. Epoxy primer must be scuff sanded to provide tooth adhesion before re-coating with Poly-Tone. regardless of the cure time. Refer to Poly-Fiber Metal Finishing literature for information on preparation and corrosion protection.
Pigments may hard settle after 3 months storage. We recommend inverting the can every 30 days to avoid pigment compaction. Pigments hard settled in extended storage should be dislodged from the bottom with a clean tool, then dispersed thoroughly by agitating with a double-action paint shaker for 5 minutes minimum. Filter thru 60×48 or finer mesh paint filter before using.
