Characteristics
Physical & Application
For easier converting the films are delivered with a removable protective top film.
These special effect films are unique translucent films that reflect the light to produce a glossy chrome
appearance in a finished graphic.
This intermediate to long term film can be applied to any plastic sheet. Film SC7755 SE-520 can be
thermoformed on a high temperature Copolyester sheet.
It is designed for use on first or second surface signs in an internally illuminated sign box.

Shelf life Use within two years from the date of manufacture on the sealed original box.
Use within one year after opening the box.
Storage conditions +4°C to +40°C, out of sunlight, original container in clean and dry area.
The shelf life as defined above remains an indicative and maximum data, subject to many external and noncontrollable factors. It may never be interpreted as warranty.
Flammability standards are different from country to country. Ask your local 3M contact for details, please.
The durabilities mentioned in the table below are the results of illustrative lab tests. The values show the best
performance expected from these products, provided that the film will be processed and applied
professionally according to 3M’s recommendations.
The durability statements do not constitute warranties of quality, life and characteristics.
The durability of products is also influenced by:
the type of substrate and thorough preparation of the surface (with 3M™ Surface Preparation System)
application procedures
environmental factors
the method and the frequency of cleaning
Unprocessed film The following durability data are given for unprocessed film only!
Climatic zones Graphic durability is largely determined by the climate and the angle of exposure.
Find below a table showing the durability of a product according to the angle of
exposure and the geographical location of the application.
Northern Europe, Italy (north of Rome), Russia
Mediterranean area without North Africa, South Africa
Gulf area, Africa

Notice!
Flat, or rolled film side out on 130 mm (5 inch) or larger core. These methods help to prevent the liner from
wrinkling or application tape, if used, from popping off.
Non vertical applications are neither recommended nor warranted.
Thermoforming with high temperatures is not recommended!
Printing on film is not recommended.
The use of these films in multi-layer constructions is not recommended.
Do not apply any graphic protection to film surface.
Based upon cutting evaluations the minimum height for text is 25 mm using upper and lowercase Helvetica
Medium. The stroke width should not be lower than 1 mm.
The variable characteristics of electronically controlled cutting equipment require users to verify their specific
requirements.
Dull blades impart a serrated look to the edge of the cut film.
The ideal weight slightly scores the liner. Too little weight does not cut completely through the film and the
adhesive. Excessive weight cuts the liner and causes the blade to drag, accelerating wear and creating a
serrated cut edge on the film.
The excess film should be weed (removed) as soon after cutting as practical. This is to minimize the effect of
possible adhesive flow.
Temperature and relative humidity are minor considerations, but avoid extreme or rapid fluctuating
conditions.
There are unique health and safety considerations that must be understood prior to vacuum forming faces
using translucent films.
Refer to Instruction Bulletin 5.16 ‘Thermoforming’ for special recommendations, limitations and processing
requirements when forming with applied films.
>Instruction Bulletin 5.16 ‘Thermoforming'<
Store the film in the same environment as the cutting equipment.
For more details refer to our instruction bulletin 4.1 ‘Sheeting, Scoring, Film Cutting’, please.
>Instruction Bulletin 4.1’Sheeting, Scoring, Film cutting'<
Forming of applied film on sheets should not exceed 50% elongation.
Film temperatures of more than 165°C may cause the silver appearance to loose gloss and become dull as the
film is stretched. To low temperatures cause the film to wrinkle around the returns.
Without diffusion light sources will be seen through the translucent silver film when illuminated.
Do not forget to remove the clear protective top film from the mirror surface before drying/forming.

Refer to Instruction Bulletin 5.1 ‘select and prepare substrates for graphic application’, for general application
information.
See product bulletin ATR ‘application tape recommendations’ for information about selection and use of
suitable application tapes for this product, please.
The application of colored or printed film onto glass with sunlight exposure can lead to glass breakage
through thermal expansion of the glass. The local conditions must be examined for the danger of glass break
by uneven heat absorption through sun exposure. Type of glass (insulation glass, float glass, LSG, toughened
safety glass, semi-tempered glass, etc.), glass dimension, joint condition, flexibility of the sealant, quality of
the edge finishing, geographical orientation and partial shadow during sun exposure are the determining
factors. Light color designs and application on the outside of the window are to be preferred. A free nonapplied framework of 4 mm around the entire window front can help to dissipate the absorbed warmth.
According to common knowledge a thermal crack can occur at temperature differences of approx. 130°C
(toughened safety glass), approx. 40°C (float glass) or approx. 110°C (semi-tempered glass). Coldest place is
usually under the framework in the embedded joined window part, the warmest place is typically on the
darkest place in the format. Because of the many above mentioned factors, glass breakage cannot be fully
predicted, therefore 3M does not accept liability for glass breakage when using this film for window graphics.
This bulletin provides technical information only.
All questions of warranty and liability relating to this product are governed by the terms and conditions of the
sale, subject, where applicable, to the prevailing law.
Use a cleaner designed for high-quality painted surfaces. The cleaner must be wet, non-abrasive, without
strong solvents, and have a pH value between 3 and 11 (neither strongly acidic nor strongly alkaline).
Refer to Instruction Bulletin 6.5 ‘storage, handling, maintenance and removal of films and sheetings’, for
general maintenance and cleaning information.
Before using, the user must determine the suitability of the product for its required or intended use, and the
user assumes all risk and liability whatsoever in connection therewith.
As outdoor graphics age, natural weathering occurs causing a gradual reduction in gloss, slight color changes,
some lifting of the graphic at the edges or around rivets, and ultimately a minor amount of cracking.
These changes are not evidence of product failure and are not covered by a 3M warranty.
