Note: The following technical information and data is intended as a guideline to assist customers in

selecting 3M? Reclosable Fasteners for further evaluation. This technical information is not

product release specifications or standards.

Solvent Resistance: The polypropylene backing, stems with mushroom top should

resist attack by most common solvents and alkaline solutions. The adhesive on 3M?

Dual Lock? Reclosable Fasteners SJ3551, SJ3552 and SJ3550 may be affected by

some common laboratory solvents and transportation fluids (gasoline, motor oil, etc.)

Tests should be conducted by the user to evaluate the solvents and exposure time

expected for the actual application.

Plasticizer Resistance: The adhesive on Dual Lock reclosable fasteners SJ3551,

SJ3552 and SJ3550 has reasonable resistance to plasticizers found in many common

flexible vinyls or other materials containing high levels of plasticizing materials.

Tests should be conducted by the user to evaluate the plasticizer resistance for the

chosen application, environmental exposure and duration for the actual application.

Other products to evaluate for plasticizer resistance is the family of 3M? Dual

Lock? Reclosable Fasteners SJ3560, SJ3550CF or 3M? Scotchmate? Reclosable

Fasteners SJ3522 and SJ3523.

Flammability Resistance: Dual Lock reclosable fasteners SJ3551, SJ3552 and

SJ3550 pass FMVSS 302 flammability tests when attached to a thin metal panel. If

you need reclosable fasteners that pass many of the other standard flammability tests

(such as FAR 25.853, ASTM E-162, ASTM E-662, BSS-7239, etc.), it is suggested

that you refer to 3M Scotchmate Flame Resistant Reclosable Fasteners Data Pages

(70-0709-3976-7 and 70-0709-3978-3).

Environmental Effects: Temperatures between -20°F (-29°C) and 200°F (93°C)

should have minimal affect on closure strength. To maintain performance when

exposed for extended periods to sunlight or ultraviolet radiation these products

should be placed between two opaque or UV resistant surfaces. Specific testing

under the expected environmental conditions is recommended.

Water (Humidity) Resistance: Closure strength should not be affected by

prolonged exposure to water or humidity. Once bonded to the substrate the adhesive

has high resistance to moisture under typical use conditions. Exposure to elevated

heat and chlorine or bromine may compromise the adhesive performance to the Dual

Lock reclosable fastener backing.

Volatile Outgassing: Volatile outgassing, as per ASTM E595, is one important test

in determining the suitability of materials for spacecraft. Generally products with

acrylic or no adhesive have lower volatile outgassing values. Products tested

at the Goddard Space Flight Center can be found at the following web site:

http://epims.gsfc.nasa.gov/og-cgi/sectionb/sectionb html.sh.

Sterilization/Autoclaving: These Dual Lock reclosable fastener products have not

been tested for performance after sterilization or autoclaving processes. It is

recommended that the customer evaluate the suitability of the Dual Lock reclosable

fastener product for these characteristics typical of what is expected for normal usage.

Washing and Dry Cleaning: The adhesive present on these Dual Lock reclosable

fastener products may make them unsuitable to washing or dry cleaning processes.
