release fertilizers in China, has completed commissioning of the second
phase of its 100,000 ton per annum
(tpa) expansion of the Heilongjiang
facility in China. The 50,000 tpa
polymer/sulfur coated compound
(PSCF) plant was completed on
budget and ahead of schedule.
Hanfeng announced the completion
of the first 50,000 tpa sulfur coated
NPK (nitrogen, phosphate, potash)
compound fertilizer plant (SCF) in
November 2007.
Both coating technologies, developed by Hanfeng’s own R& D team in
Shanghai, allow the custom designing of various multiple nutrient
blends, including micronutrients.
The PSCF product, using Hanfeng’s
polymer coating, provides more precise control of the releasing period
for the nutrients. Although traditionally more expensive to manufacture, Hanfeng’s polymer coating
process allows the company to produce and sell the PSCF at very competitive levels.
The existing Heilongjiang tower
granulation plant will supply the
compound NPK granules for the
high-margin specialty coating
plants. With the completion of the
50,000 tpa second phase, the
Heilongjiang facility has 450,000 tpa
of design capacity, with a full product offering that includes homogeneous granules, blended products,
compound fertilizers and specialty
coating products. Combined with the
Jiangsu facility, Hanfeng now has
700,000 tpa of design capacity from
seven plants in China.

CLIFFORD K SCHOFF NAMED WINNER OF ROY W. TESS AWARD
Dr. Clifford K. Schoff formerly of PPG Industries and now a private consultant will receive the Roy W. Tess Award in Coatings for 2008. The
announcement was made by the Officers and the Award Committee of the
Division of Polymeric Materials: Science and Engineering (PMSE) of the
American Chemical Society.
Dr. Schoff is recognized as one of the world's leading experts in the area of
coatings defects, electropaint-substrate interactions, paint flow and rheological measurements, mechanical properties and cure of coatings. He has
contributed more than 40 papers,
articles and chapters to the coatings
literature and recently published his
40th one-page “Coatings Clinic” in
JCT Coatings Tech. Dr. Schoff has led
ASTM Subcommittee D.01.24 on
Physical Properties of Liquid Paints
for more than 20 years, has written
numerous ASTM test procedures and
has championed the use of ASTM
standards. He currently is Secretary
of ASTM Committee D01 on Paints
and Related Coatings, Materials and
Applications. Dr. Schoff is Chair of
the Federation of Societies for
Coatings Technology (FSCT)
Dr. Clifford K. Schoff Publications Committee, a member
of the Editorial Review Board, one of
the technical editors of the Journal of Coatings Technology and Research and
is active in the Pittsburgh Society for Coatings Technology.
Dr. Schoff’s main research interests have involved physical testing and measurement and their application to solving product and process problems and to
developing new products, primarily in industrial and automotive coatings. Late
in his career at PPG, he gained valuable practical experience in working to
improve appearance and reduce dirt and other defects at automobile and
motorcycle plants. He has developed lectures on surface defects, failure analysis, cure, rheological measurements, corrosion, pigment dispersion, surface
preparation, optical microscopy and other related topics and presented these
lectures world-wide (North America, South America, Europe, Asia) for PPG
Industries Inc., FSCT and privately.
