THUNDERBIRD EPOXY
TECHNICAL DATA
Hardness (Sward-Rocker)....................................... 65
Impact Resistance (22 gauge steel)..........................173 inch-lbs.
Flexibility (1/2" mandrel)
a) at -60 degrees F. .......................................cracks
b) at room temperature....................................passes
c) at +180 degrees F. ....................................passes
Tabor Abrasion (gms. wt. loss after 1000 cycles) ...0.035
Color (clear mixes, Hellige Comparator) ..................4.5
Chalking (300 hrs. in weatherometer) ......heavy (surface only: removable)
Weathering and Waterproofing... Virtually a complete moisture vapor barrier. Surface exhibits moderate chalking after extensive exposure to ultraviolet (sun) light. Four years exposure shows that chalking, on surface only, may be easily removed by washing or wiping with the underlying coating still having good gloss without a film breakdown. The good film integrity indicates continued protection.
Corrosion Resistance ... Both vehicle and pigment contribute to the high degree of resistance to corrosion.
Gloss (Initial) ................................................................. 100
a) after 300 hrs. in weatherometer ............................... 75
b) after 600 hrs. in weatherometer ............................... 30
c) washing after 600 hrs in weatherometer ................... 90
Heat and Cold Resistance
Passes 25 cycle heat and cold test.
(-65 degrees to +200 degrees F.)
HEAT RESISTANCE
24 hrs. at 200 degrees F. ............................... No discoloration
8 hrs. at 250 degrees F. ............................... No discoloration
96 hrs. at 250 degrees F. ........................... Slight discoloration
8 hrs. at 275 degrees F. ........................... Slight discoloration
24 hrs. at 275 degrees F. ..................... Moderate discoloration
8 hrs. at 350 degrees F. ..................... Moderate discoloration
24 hrs. at 350 degrees F. ......................... Severe discoloration
8 hrs. at 400 degrees F. ........................ Severe discoloration
Temperatures to 500 degrees F. caused film to turn yellow and with continued exposures to brown, then black. There was no carbonization and no effect to gloss. Adhesion, chemical resistance and electrical properties are retained. At temperatures above 600 degrees F. film carbonized. It is important to note that the effect to heat in multiple exposures is cumulative. Therefore many short exposures to heat will have a similar effect to one long exposure.
Moisture Vapor Transmission Rate (0.025 gms./24 hrs.: 1.5 mil coating thickness - Payne Cup).
a) Theoretical - on 2 mil thickness or 0.0508 mm., 4.05 mg. of
moisture permeates through 100 square inches at 100 degrees
F. in 24 hours.
b) Actual Test - (24 hrs. at 100 degrees F.) 49 mg. loss
.0685 mm. coating thickness 10 square centimeter area.
On the basis of grams per 100 square inches the rate of
moisture vapor transmission is 3.16 grams per 24 hours at
100 degrees F.
Heat Reflectivity ......................................................... 81-83
Light Reflectivity (average)
a) white #200 - gloss................................................. 75%
b) white #200 - satin.................................................. 82%
c) white #200 - flat.................................................... 88%
Flash Point (Tag closed cup)...varies with formula 40-100 degrees F.

THUNDERBIRD EPOXY
CHEMICAL RESISTANCE
Film thickness 4-6 mils normal 3 coat application. Coatings post cured at 200 degrees F. for 30 minutes. Coatings cured 7 days at room temperature provide slightly less resistance to chemicals and solvents.
KEY: NC - No change; SS - Slightly softened;
S - Softened; F - Failed; E - Excellent.
