Dry Erase Specialty PSA Overlaminate films
Special use films for indoor or short -term outdoor graphics for up to 2 years durability with vertical exposure under normal conditions. Each substrate is coated with 1 mil (25 µ) permanent solvent acrylic adhesive. The adhesive is protected by a 70# (105 gsm) white paper release liner coated both sides with PE and siliconized on the release side.
Dry Erase - 2.0 mil (50µ) Gloss clear Polypropylene, suitable as a write / erase surface. (Gloss level 90 @ 60° reflection) Dry erase markers wibe clean for calendars, planners, maps, displays, courtroom graphics, and menu boards.
Product Data Sheet
Polypropylene laminating film is suitable for short-term indoor signage on flat or slightly curved surfaces with vertical exposure and application temperatures of 40° F to 176° F. Durability of the laminate depends on proper drying/curing/ outgassing of the ink. Printed PVC must be allowed to dry for 24-48 hours at 70° F prior to lamination to allow residual solvent to evaporate. Failure to do so may result in delamination, tunneling and shrinkage of the PVC and or adhesive failure.
The amount of dry time required is a function of the amount of ink applied, the image printed, relative humidity, printing conditions, etc. and all prints are not the same nor dry at the same rate. There may still be solvent in the ink that has not completely dried at the time of lamination. Although all PVC outgases, in some cases this process is accelerated by the presence of excess solvent in the ink and heat from high UV exposure.
These Durability estimates apply only to the laminating film not to the printed image. They are based on accelerated aging tests and outdoor exposure, under conditions experienced in vertical exposure and in “normal” temperate climates. Exposure to severe humidity and ultraviolet light as in Southern States or desert regions will cause rapid deterioration. This also applies to polluted areas, high altitude, horizontal and/ or south-facing exposure. Because of these varying climate conditions there is no standard outdoor life durability; it is only a reference for choosing the proper product.
