CARB POSTS FINAL REPORT ON Relationship between

Published August 11, 2005
“Correlation Between Solids Content and Hiding as it Relates to the Calculation of VOC Content in Architectural Coatings,” the final report for a research project conducted for California’s Air Resources Board (CARB) by Cal Poly, San Luis Obispo, has been posted at CARB’s web site.
The project’s goal was to determine the relationship between the volume percent of solids in coatings and the hiding of the coatings. The basis for the calculation of VOC content in paint rules (“VOC, less water and less exempts”) is that there is a consistent relationship between solids and coverage, or hiding, especially in typical flat and non-flat house paints.
The researchers determined that although for a particular coating the hiding improves as the solids content increases, across different coatings, higher solids content does not necessarily equate to better hiding. In many cases, a 35% solids by volume water-based coating hides as well as a
60% solids by volume solvent-based coating. Accordingly, since the basis for using “VOC, less water and less exempts” was not supported by this study, this standard for the VOC content for house paints does not appear to be the ideal standard.
The researchers developed a different standard, termed “hiding VOC,” which is defined as the amount of VOCs emitted by hiding (as opposed to simply covering) one square meter with a paint. Using this measure, among the flat and non-flat paints tested, solventborne coatings on average emitted over ten times as much VOC to hide the same area as the waterborne paints did, according to CARB.

BASF Takes Complete Ownership of JV with NOF
BASF is taking complete control of BASF NOF Coatings Co. Ltd. (BNC), its joint venture with NOF Corp. BASF will operate the company under the name of BASF Coatings Japan Ltd.
Financial details of the accord were not disclosed. The joint venture was formed in October 2000.
The acquisition encompass all of BNC’s assets, including the production sites in Totsuka, Kanagawa and Ako, Hyogo prefectures.
Effective April 1, more than 530 employees began working for BASF Coatings Japan Ltd., including current delegates from NOF. “This transaction underlines BASF’s clear commitment to Japan as an important coatings market,” said Klaus-Peter Löbbe, member of BASF’s board of executive directors and responsible for the coatings business. “The integration into BASF’s global organization will enable us to enhance the value of our services and products to customers in Japan.”
