3M™ Scotchcal™ Overlaminate 8580
Long-term Overlaminate - 3-D vehicle wrap, transparent gloss
3MTM ScotchcalTM Overlaminate 8580 is a thin, extremely flexible, cast film providing high conformability for applications into recesses and deep channels.
This material provides additional ultraviolet and durable physical protection for selected graphic constructions. It is intended for providing graphic protection to digitally imaged graphics.
The cold roll lamination method must be used when applying Overlaminate 8580 to Graphic Film IJ380.
Important Note: Care must be taken not to create tension in the overlaminate during the laminating process. Tension will cause the flexible 8580 to stretch, especially at higher ambient temperatures. This could result in the graphic construction lifting when applied into deep recesses.

Suitable for cold lamination only.
It is recommended to allow a minimum of 24 hours after printing of 3M Controltac Graphic Film IJ380 before laminating the graphics using 8580 overlaminate.
Inadequate drying can result in graphic failure including curling, increased outgassing, increased shrinkage and adhesion failure, which are not covered under warranty.
Always build enough time into your process to ensure adequate drying of the graphic. Poorly dried film may become soft and stretchy, and the adhesive may become too aggressive. This can cause difficulty when applying an overlaminate, rolling the graphic, and applying the film.
