HW8Y2 Yellow and HW8W1 White

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.
