Product Description
Theses paints meet the Washington State specification for Instant Dry Highway Marking Paint.
These are extremely fast drying paints, less than 60 seconds dry to no-pick up and designed for no heat application. They may be applied by air or airless equipment withouth the need for coning and with a minimum of traffic control.
APPLICATION DATA:
1. Coverage:93 sq ft. per gallon @ 15 mils wet film thickness, yields 8-10 mils dry film.
2. Reflective glass media: Type A drop on beads at 6-8 lbs/gallon dispensed with pressurized bead gun system.
3. Storage stability: 6 months with a viscosity increase of less than 10 KU (krebs Units) measure of viscosity at a temperature of 50 degrees F and above.
4. Minimum application: Should not be applied below 50 degrees F.
PHYSICAL PROPERTIES OF THE COATING:
1. ASTM D562: Viscosity (in krebs units):
A. At 70 degrees F – 70-75 KU
B. At 50 degrees F – 86 KU max.
C. At 122 degrees F – 66 Ku min.
2. ASTM D1475: Weight per gallon at 70 degrees F:
White – 12.00 lbs min.
Yellow – 12.00 lbs min.
3. ASTM D2805: Contrast ratio at spread rate of 320 sq ft per gallon:
White – .92 min % of complete hiding over black and white.
Yellow – .92 min % of complete hiding over black and white
4. ASTM E1347 Daylight reflectance (at 10 mils wet film thickness)
White – 86 min of 100% standard
Yellow – 64 min of 100% standard
5. ASTM D1644 Non-volatile content 65% – 68% solids. Measure of binder plus pigments weight total.
6. ASTM D2371 Pigment content of total weight:
53% measure of dry ingredients
7. ASTM D1210 Dispersion, Hegman standard gauge: 2 min fineness
8. ASTM D522 Flexibility: Pass 1/2 in mandrel bend of paint film cast on a test panel.
9. Dry to no-pick-up (beaded): 15-35 seconds based on a road cry test.
10. ASTM D969 & D868 Bleeding over asphalt: 90% min brightness maintained.
The material shall not show evidence of heavy caking or settling which requires mechanical means to return the product to useable condition for a period of one year from the date of manufacture or date first shipped. These paints do not form a dried surface layer or skin. They re-dissolve in their own solvents preventing a thick build up in drums or on tank walls.
PACKAGING:
These paints are available in 50 gallon steel drums, 5 gallon pails, and 340 portable tanks.
