not be VOC-compliant in some regions of the country.
The use of metallizing system 6-Z-A is advocated for
use on steel immersed in very turbulent, ice- and
debris-laden fresh waters. Exposures such as this
may erode and cause total failure of the standard
abrasion-resistant paint systems found in Section
09964 in as little as 1 year. System 6-Z-A, with
appropriate sealing and top coating, will provide
superior protection for this type of severe service.
The use of metallizing system 8-A is endorsed for
high temperature atmospheric exposures. Paint
coatings do not generally perform as well as thermal
spray coatings of aluminum for high temperature
exposures such as stacks. The use of metallizing
system 6-Z-A is recommended for use as a zebra
mussel repellent coating where the use of such a
coating is deemed necessary. System 6-Z-A is longer
lived and has a lesser environmental impact than
conventional copper-containing antifouling coatings.
The use of this guide specification should be
limited to work described in this note.
The metallizing systems described in this document
are intended for corrosion protection of cold and
hot rolled steel. Metallizing systems described
herein are not intended for use on stainless steel,
aluminum, bronze, copper, plastic, rubber, wood,
masonry, and painted surfaces. Coating systems
contained herein should not be specified for potable
water tank interiors, moving parts or wear surfaces
of machinery, or for surfaces subject to strong
acids or bases.
