screen dimensions) and providing a
light output of 3,300 lumens, the new
Eidophor Model 5177 Multi-Standard
HDTV projection system projects up
to 40-foot-wide images on regular motion picture screens.
HDTV sources include: cameral

HIGH PERFORMANCE
EPOXY MASTIC COATING

The Du Pont Company has introduced a high solids epoxy mastic coating called Du Pont 25P for industrial
maintenance and new construction
applications. The new multiple-use
coating provides effective corrosion
protection along with significant time
and cost benefits.
The new product provides a tough,
durable coating with outstanding adhesion for use on steel, galvanized
steel, masonry, concrete, and wood in
both corrosive and non-corrosive environments. It is recommended for industrial, commercial, institutional,
and architectural applications where a
long-lasting epoxy coating is desired.
It can be applied easily by brush,
roll, or spray and requires no induction
time. It has a long usable pot life and
dries quickly and recoats easily. Based
on its high solids formulation, 25P
meets all air pollution regulations.
Du Pont 25P is available as a satin
finish in a wide range of color plus
aluminum, all with hiding power. *

SILICONE FOAM SHEET

CHR Industries, Inc., has introduced a
new low density, flame retardant silicone foam sheet which provides outstanding performance for applications
in construction and furnishings.
COHRlastic"' silicone foam is manufactured by CHR Industries from
GE's two-component RTF 762 silicone
system. RTF 762 is u.L. rated 94 V-O,
and COHRlastic foam has been shown
to wi thstand a 2100°F flame for more
than ten minutes without burnthrough in thicknesses down to V,ths
of an inch. With a density of 11
pounds/cu. ft., the new material is also
an economical choice.
According to CHR, it generates very
little smoke and unlike urethane
foam, it does not release cyanide ga
when burned. The material offers excellent thermal and acoustical insulating values, as well as resistance to
a broad range of chemicals and thermal conditions. Additionally, it resists

softening and outgassing in demanding applications.
COHRlastic silicone foam is noncorrosive, for use with metals and in
hostile enviromnents, has low moisture absorption and low compression
set. With these characteristics, CHR
may be used in a wide variety of applications, such as fireblocks, thennal
barriers, noise and vibration dampeners, insulation, and high performance gaskets or seals.
COHRlastic silicone foam is available for worldwide distribution from
CHR distributors. Colored gray, it is
supplied in 36-inch wide roll stock in
thicknesses ranging from '116 to 1/2inch and i available plain or laminated to any of a wide range of
substrates.
