5. PALGARD Enhanced Attributes (Compared with regular PALSUN):
a. Visible Light Transmission: Improved by PALGARD silica coat by approximately 1.5% (to 91%)
b. Yellowing Index: Improved by PALGARD silica coat to < 0.75.
c. Chemical Resistance: PALGARD coated side presents better resistance than the non-coated side, or
parallel PALSUN or PALTOUGH. It could be subjected, for limited periods, to harsher chemicals or more
effective cleaning agents during removal of persistent grime or occasional graffiti.
d. Cleaning Persistent Grime & Graffiti Removal: PALGARD coated side can withstand spray-paints,
motor oils, alcohol based markers & other relatively aggressive chemicals along with brisk use of alcohol,
kerosene and even gasoline as cleaning agents.
PALSUN or PALTOUGH are more vulnerable to these materials and might be harmed by contact with
them.. Damage scope depends on duration of exposure & type of chemical.
Resistance duration to each cleaning agent differs, so use it gradually, from the most gentle to the
harshest. Wash-off immediately as cleaning is completed, with lots of clean water and mild detergent.
e. Weather Resistance: PALGARD coated side(s) offers even better weathering durability, confirmed by
thousands of hours of accelerated exposure and years of field tests in harsh climate conditions.
f. Abrasion Resistance: PALGARD meets ASTM D-1044 & ANSI Z26.1 TEST #17 Taber Abrasion Test with
good results, displaying good resistance to friction & chaffing with people in crowds.
PALGARD can endure intentional abuse to a measure, however once gouged by sharp objects (knives,
screwdrivers etc), a deeply scratched surface could not be restored.
