A pplication Techniques Bond strength is dependent upon the amount of adhesi ve-to-surface contact
de veloped. Firm application pressure helps develop better adhesive contact and
improves bond strength.
To obtain optimum adhesion, the bonding surf aces must be clean, dry and well
unified. Some typical surface cleaning solvents are isopropyl alcohol or heptane.
Note: Carefully read and follo w the manufacturer’s precautions and directions for
use when working with solv ents. These cleaning recommendations may not be in
compliance with the rules of certain Air Quality Management Districts in California;
consult applicable rules before use.
IMPORTANT: For optimum liner clarity on 3M™ Double Coated Polyester Tape
442F and 442DL products, it is recommended the tape product be processed from
supplied roll format into converted product with-in six months of the manufacturing
date. After six months the liner clarity may be reduced due to a haze effect. This
liner clarity does not impact adhesive or liner performance over the shelf life of the
product.
Ideal tape application temperature range is 70°F to 100°F (21°C to 38°C). Initial
tape application to surfaces at temperatures below 50°F (10°C) is not recommended
because the adhesi ve becomes too f irm to adhere readily. Howeve r, once properly
applied, lo w temperature holding is generally satisfactory.
Features • Polycoated paper liners and the polyester liners of fer moisture stability
• 3M™ Double Coated Polyester Tapes 442F and 442DL (double linered) also offer
an extended shelf life of an additional six months.
• Polyester film carrier at its center core which enhances the workability when
laminating to v arious types of surfaces.
• Film also enhances the die cutability of the finished product.
• Provides clean removability from many surfaces.
A pplication Ideas These tapes are ideal for bonding together a wide v ariety of similar and dissimilar
materials such as rubbers, metals, glass, papers, paints and many plastics. Some
application ideas include:
– Splicing of films, foils, papers, f abrics.
– Holding objects where high shear forces are encountered.
– Holding grinding and polishing pads.
– Miscellaneous joining and holding uses.

A pplication Equipment Wide web lamination
To apply adhesives in a wide web format, lamination equipment is required to
ensure acceptable quality. To learn more about working with pressure-sensitive
adhesives please refer to technical bulletin, Lamination Techniques for Converters
of Laminating Adhesives (70-0704-1430-8).
