Calculation Examples
U.S. Non-vertical 50% (0.5) 0.5 x 5 years = 2.5 years
0.5 x 9 years = 4.5 years
Desert Southwest Vertical 70% (0.7) 0.7 x 5 years = 3.5years
0.7 x 9 years = 6.3 years
Desert Southwest Non-vertical 35% (0.35) 0.35 x 5 years = 1.65 years
0.35 x 9 years = 3.15 years
U.S. Horizontal 0% (0.0) 0 years (no Warranty Period)
(2) Abrasion and Loss of Gloss Abrasion damage and loss of gloss are not covered by any 3M Warranty. This is considered

9. Bulletin Change Summary Modified and new content is marked with a black bar in the margin. Diffuser films 3635-30,
3735-50, 3735-60 now can be used for first surface applications without being covered by
a UV-resistant 3M film. Updated Light Transmission values. Links to flammability reports are
included in Physical Characteristics. The Warranty Periods of film 3635-30 are now
consistent with 3735-50 and 3735-60; most non-vertical Warranty Periods equal one-half
of their corresponding vertical exposures. The 3M Related Literature section has been
replaced by direct links to the most current versions of Bulletins or warranty information you
may need to successfully use this product. All links are blue underlined text.
