Technical Data February, 2006

Product Description

3M™ Cleanroom Vinyl Tape 1251 is a various colored (5 colors and transparent)
vinyl plastic film tape with a rubber adhesive ideal for many color coding, sealing,
abrasion protection, wrapping, lane marking, construction, and in-process applications.

Construction

Backing Adhesive Color Standard Roll Sizes

Pigmented and Rubber Yellow, red, blue, 1/2 in., 3/4 in., 1 in., 2 in. x 36 yds.
transparent green, white, and (13 mm, 19 mm, 25 mm, 50 mm x 33 m)
vinyl plastic transparent

General Information

• Product is cleaned and packaged in cleanroom.

• Rolls are wound onto plastic cores and bagged with Class 100 clean film.

• Best results are attained when applied to clean, dry surfaces between 60° to 85°F
(15° to 27°C).

• Conformability and dead stretch properties are ideal for taping, wrapping or
sealing many curved or irregular surfaces.

• Pigmented backings maintain their vivid colors even when exposed to heavy
abrasion.

Note: While 3M tape 1251 resists many common solvents, it should not be exposed

to ketones, chlorinated hydrocarbons, and esters, which may cause the
backing to swell or curl.
