WHITENESS: The draw-downs measured were produced by Southern Exposures using the exact same paint formulas with the only variable being the pigment used (same volume of each pigment in each formula), in this case NCS-12, NCS-15, and Minex 4.
DRAWDOWN #1 MINEX HESS NCS-15 DELTA
Berger Whiteness 84.11 83.50 -0.61
CIE Whiteness 83.67 82.93 -0.74

Crystalline Silica• Crystalline Silica (respirable) has been identified by the International Agency for
Research on Cancer (IARC) as a “Group 1” carcinogen. OSHA therefore requires all products containing more than 0.1% crystalline silica to be labeled as a cancer hazard.
• Crystalline Silica is the principal cause of the silicosis and related lung diseases and is responsible for approximately 300 deaths in the US each year.
• Respirable Crystalline Silica is federally regulated by the EPA, FDA, & OSHA. NIOSH also considers crystalline silica to be a carcinogen.
