3M ? Reclosable Fastener SJ3000
Thin Hook and Loop Back to Back
Typical Performance
Properties and
Characteristics
Unless stated, typical system performance characteristics were measured under controlled laboratory
conditions of 72°F ± 5°F (22°C ± 2.7°C) and 50% ± 10% relative humidity. The user should evaluate
products in the actual application to ensure suitable performance for the intended use.
Fastener Product
3M? Reclosable Fastener SJ3000
Performance tests are determined by measuring the performance of the entire reclosable fastener when
the hook on one side is engaged to the loop on the other side of the fastener.

Cycle life is the number of cycles (openings and closings) that the fastener is subjected to while maintaining
50% or greater of the 2nd closure peel values. Initial peels are slightly higher
SHELF LIFE
Twenty four months from date of manufacturing
when stored in original packaging at 70°F ± 10°F
(21°C ± 5.5°C) and 50% ± 10% relative humidity.
Note: Long Term Static Load: Conditions such as temperature variations, engagement area, closure pressure
and vibrations or side to side movement after engagement or exposure to prolonged periods of moisture,
ultraviolet or other environmental factors can affect the closure strength and long term static load performance.
Reclosable fasteners may slip or creep in the direction of the static load forces when subjected to static loads at
temperatures or weights greater than indicated. The user is responsible for designing the amount of fastening
area based upon the specific conditions for the application. Four square inches of fastening area per pound
(57.3 sq. cm/kilogram) of static load is suggested as a starting point for such evaluations.
Additional
Performance
Characteristics
Chemical Resistance: The polypropylene hook and polyester loop resist incidental attack
by most common solvents and alkaline solutions. Acid solutions may cause deterioration
of the loop. Small amounts of oils, mold release agents would not be expected to cause
performance issues when in contact with 3M? Reclosable Fastener SJ3000, except for
the possible difficulty in starting a wrap.
Plasticizer Resistance: The polypropylene hook and polyester loop should have good
resistance to direct contact with most plasticized materials.
Flammability Resistance: Reclosable Fastener SJ3000 will not pass common
flammability tests when tested unattached to an substrate. If you need reclosable
fasteners to meet many of the standard flammability tests (such as FAR 25.853,
FMVSS-302), you may want to consider using 3M? Reclosable Fasteners
SJ3418FR/19FR, SJ3518FR/19FR and SJ3486FR/87FR.
Water (Humidity) Resistance: Closure strength should be minimally affected by high
humidity conditions.
