Mactac 6600 MACmark Cast Marking Film Light Grey
Product
MACcast 6600 High Performance Cast Vinyl Series
Product Description
MACcast 6600 is a premium Mactac film designed for applications over complex curves like rivets,
corrugations and other irregular surfaces. The face is a 2.0-mil cadmium-free cast vinyl, durable yet,
highly flexible for conformability over difficult surfaces with a high gloss finish and designed for superior
cutting and weed ability. The product is coated with a high performance, permanent, clear solvent
acrylic adhesive protected with 78# bleached white kraft liner or 90# Polycoated for stability and layflat.
The products exhibit excellent dimensional stability in high performance permanent marking
applications that require up to 8 years outdoor durability. Mactac offers a wide variety of standard,
opaque, high gloss colors with an additional twenty metallic-flake films.

Durability
Black, White and all opaque colors 8 year, all metallic films have a 5-year outdoor durability. This use-life
estimate is based upon accelerated age studies based on vertical applications under “normal” temperate
climates. Exposure to severe temperatures, ultra-violet light and tropical, sub-tropical or desert regions
will cause more rapid deterioration. This also applies to polluted areas, high altitude and south facing
exposure. This also applies to polluted areas, high MACmark films are not specifically intended for
printing.
Printability
Printability is not warranted. However, we have created the following guidelines if printing is desired:
1) For screen printing: Limit the screen ink to two or three colors. While the liner is an excellent liner,
it is designed for plotter cutting. Sometimes too much heat may result in the liner ‘waving’ a little
which can cause registration issues when additional colors are used. Mactac recommends Nazdar
3500 series UV cured screen inks.
2) If printing UV inkjet; make sure the vacuum (if flatbed) is strong enough to hold the liner down
tight. Typically it is, but vacuums are notoriously weak, especially as they age.
3) If printing with solvent inks; limit the inks to a total of 270% saturation. Use a generic ICC profile for
either 2 mil cast of 3.5 mil calendared vinyl films as a starting point.
4) Thermal transfer printing: all MACmark gloss films are thermal transfer printable. We strongly
recommend the use of a web cleaner prior to printing due to the potential presence of paper dust
from the white kraft paper liner.
Shelf Life
Two years when stored between at 60- 80°F (15 – 25°C) and 50% relative humidity or less.
Gasoline Resistance
A sample is prepared in the same manner as for the Chemical Resistance Test and is sprayed several
times with gasoline followed by drying at each stage. Low and high octane gasoline test ‘good’.
Limitations
1) The user is responsible for determining the product’s suitability, including adhesion and if needed,
removal characteristics when used in applications other than listed specifically in this Performance
Guide.
2) If there are any questions about applications, please contact your Mactac sales representative to
discuss your requirements for recommendations.
3) If this is a printed Performance Guide it is an uncontrolled document. Please check the Mactac
website for the latest, most up-to-date version.
Recommendations
1) Application of MACcast 6600 is made easier if Mactac pre-spacing tape is used.
2) Where exposures to chemical and solvent spills are likely to occur, edge sealing of decals with a
varnish or clear coat will prevent edge lift. Correct varnishing of decals gives greater protection and
longer end-use life against any prolonged effect of weathering, abrasion and other erosive effects such
as frequent cleaning. 6689-03 Light Grey
