Silicone Splicing Tape

253

Product Description

3M™ Silicone Splicing Tape 253 is a single-coated paper tape with a modified poly

liner implemented as a second liner on the FACE SIDE of the tape. This second liner

is added to help ensure roll quality, ease of unwind and protection of the adhesive

against contamination until the splice is ready to be made.

Features

• Special silicone adhesive that exhibits excellent “web-grab” and peel adhesion to

many silicone treated materials.

• Silicone-coated backing enables the splice to be functional.

• Materials will release from the tape backing as easily as from the material itself.

Typical Physical

Properties

Note: The following technical information and data should be considered representative

or typical only and should not be used for specification purposes.

Application Techniques

• Bond strength is dependent upon the amount of adhesive-to-surface contact that

is developed. Firm application pressure and proper rub-down techniques help

develop better adhesive-to-surface contact and improve the bond strength.

• The face-side poly liner should be removed right before the butt splice is made.

This will help prevent the adhesive from becoming contaminated and help in

tape handling.
