Version #16 (0519) Approved by J. S.

LF3640G RAYZor™ Cast Gloss Overlaminating Film

The Permacolor system is a series of pressure sensitive products for mounting and protecting in the imaging industries. Pressure sensitive Permacolor provides fast, efficient processing through cold roll lamination techniques without the need for heat, drying or messy coating operations.

LF3640G is a 1.5-mil clear gloss; highly conformable cast PVC film. The product is coated on one side with a clear permanent, acrylic pressure sensitive adhesive and supplied with a smooth 60# glassine release liner. Additional UV protection is built into the overlaminating film to help extend the life of your graphic by resisting color fade caused by ultraviolet light. Can be used to laminate:

Photographic prints Solvent screen printed images HP Latex inkjet prints Water-based inkjet prints

Transparencies Solvent and eco-solvent inkjet prints Canon UVgel 356 prints

LF3640G is designed for use with GV729 and GVC929 in long-term outdoor, marine, fleet or vehicle markings on flat, curved, corrugated and riveted surfaces. Use LF3630G with RR100 in rough textured wall applications.

Additionally, this product has good resistance to detergents, alcohol and some aliphatic solvents for short periods of time. Not recommended for contact with ketones, esters, aromatic solvents and chlorinated hydrocarbons.

The outdoor durability is 5 years in outdoor vertical applications in the Central US and 7+ years indoors and up to one (1) year on indoor Floor Graphics. Horizontal application or in the Southwest regions will be 50% less. The durability of the image is mainly dependent upon the quality of the inks (see technical data sheets given by the ink manufacturers) and pressure sensitive media being used.

Two years when stored at 75°F (24°C) and 50% relative humidity or less. Note: Mactac recommends that rolls be stored on end or suspended from the core.

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.

1. We recommend you work in a controlled environment (> 72°F (23°C) and 50% RH), and condition the media in the printing room 24 hrs. before printing.
2. Ensure print is perfectly dry. Material should have 24 hrs. drying time, open to the air, and prior to lamination or transportation. Laminate through a professional laminator at 3 - 5 ft./min. Slight mottling may occur from being in the roll too long. This will go away with a little time (typically 24-hrs) in the sun. If this is not possible, simply heat the top roll on your laminator to a temperature of no more than 120°F (50°C) to remove. Caution: heating this film will allow it to stretch easier; special care with film tension will be required!
3. Since this is a very thin cast vinyl film, it is very easy to stretch, keep film face tension as low as possible to reduce this possibility.
4. Where exposure to harsh chemicals, solvents or high pressure wash is anticipated we recommend you seal the edges with varnish, heavy duty car wax or silicone in order to avoid penetration of these liquids into the adhesive.
5. To allow for easy transportation, IMAGin laminated with LF3600 Series can be rolled up, with the image out, with a minimum diameter of 7 inches (18cm). When an overlaminate does not protect the image, make sure the print is completely dry and protected in a plastic bag. During transportation or storage, avoid exposing them to extreme temperature and humidity changes.
6. Always test the combination of inks, media and laminating films prior to commercial use. Slight surface mottling may appear in this high gloss film while in the roll form due to the softness of the film itself. This will disappear after one to two days after lamination all by itself. However, if waiting is not an option, a small amount of heat (100° - 120°F) during the laminating process will remove the mottling immediately. Use care not to stretch the film during this process. Always maintain as little film tension as possible to minimize this possibility.
