Series 3420

Calendered Overlaminate

Series 3420 is constructed of a 75 micron calendered vinyl film with clear, permanent pressure-sensitive adhesive. Designed to protect and prolong the life of printed images, Series 3420 is made of a polymeric facestock and available in gloss, satin and matte finishes. Series 3420 is rated for outdoor durability up to 5 years. See Arlon’s Print Media Total System Warranty, which is available at

Optimum Performance

Actual weathering durability depends on surface preparation, surface maintenance and exposure conditions. Successful weather resistance is characterized by the retention of legibility.

Series 3420 will resist weathering best when applied to vertical or upper outboard angles. Horizontal angles, such as hood and auto roof surfaces, will deteriorate more quickly than vertical. This is due to increased exposure to sun and moisture, as well as continued high deposition of dirt and atmospheric contaminants. Arlon does not recommend its film for horizontal or close horizontal applications.

Floor Application

Series 3420 Gloss and Matte are approved under the UL 410 regulation for slip-resistance as a floor graphic material. Arlon recommends DPF 4600GLX/MLX, DPF 8200 High Tack, DPF 8000 Ultra Tack, DPF 510 GTR/MTR or DPF 510GT/MT as the compatible media. These product combinations are recommended for short-term interior floor applications for an expected life of up to 6 months. To determine the best product for the application Arlon always recommends testing on the surface prior to using the above products. Product performance can vary greatly depending on the surface type, level of foot traffic, elemental exposure, carpet type, and floor condition. Due to these variables, Arlon is unable to offer a warranty for the performance, expected life, or clean removability of these products for floor graphic applications.
