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
specifcations or standards. Unless stated differently, the typical system performance and product
properties were obtained using specific test methods under controlled laboratory conditions of 72°F ± 5°F
and 50% ± 10% relative humidity. The user is responsible for evaluating 3M reclosable fasteners under
expected use conditions to ensure suitable performance for the intended application.

Note: Long Term Performance: Conditions such as engagement area, supported weight, forces on the closure, vibrations or side to side movement, as well as
changes or prolonged exposure to environmental factors, such as temperature, ultraviolet light or humidity and other factors beyond the control of 3M can affect the
closure strength and long term performance. Reclosable fasteners may slip or creep in the direction of the static load forces when subjected to static loads at
temperatures, times or weights greater than indicated. The user is responsible for designing the amount of fastening area based upon the expected use conditions
for the intended application. Four square inches of engaged fastening area per pound of static load is suggested as a starting point for such evaluations.

System performance tests are determined by measuring the engaged system performance of the listed reclosable fasteners when used to join two 1/16" thick non-anodized aluminum
plates.
Dual Lock reclosable fastener type 250 (SJ3550) engaged to type 250 (SJ3550) and type 170 (SJ3552) engaged to type 400 (SJ3551) have approximately the same performance and
are approximately midway between the performance of type 170 engaged to type 250 (the lowest performance recommended) and type 250 engaged to type 400 (the highest
performance recommended). Type 170 engaged to type 170 as well as type 400 engaged to type 400 are not recommended as the former is too weak and the later may be too
strong potentially causing part damage or ergonomic issues.
3M? Scotchmate Reclosable Loop Fastener engaged to Dual Lock reclosable fastener may provide increased closure strength over standard Dual Lock reclosable fastener
combinations, especially after movement or vibration of the closure system. Due to this increased strength, extra care should be given to ensure the maximum bond strength is
obtained to the substrates being joined. Failure to obtain bond strengths to the substrate that are sufficiently high may cause the fastener to release from the substrate upon
disengagement.
The listed reclosable fastener combinations were engaged with firm pressure and disengaged at the rate of 12 inches (305 mm) per minute.
Maximum tensile disengagement strength is dependent upon all of the stems disengaging at the same time with the two substrates parallel to and moving away from each other.
If sections of the Dual Lock reclosable fastener lift during disengagement, the fastener will disengage in a peel or cleavage mode, reducing the observed strength.
System dynamic tensile engagement strength of Dual Lock reclosable fastener SJ3552 (Type 170) to Dual Lock reclosable fastener SJ3551 (Type 400) is 29 lbs F /sq inch
(397 kNewtons/m 2 ) and Dual Lock reclosable fastener SJ3550 (Type 250) to Dual Lock reclosable fastener SJ3550 (Type 250) is 29 lbs F /sq inch (397 kNewtons/m 2 ).
System dynamic tensile disengagement strength of Dual Lock reclosable fastener SJ3552 (Type 170) to Dual Lock reclosable fastener SJ3551 (Type 400) is 50 lbs F /sq inch
(346 kNewtons/m 2 ) and Dual Lock reclosable fastener SJ3550 (Type 250) to Dual Lock reclosable fastener SJ3550 (Type 250) is 44 lbs F /sq inch (304 kNewtons/m 2 ).
System dynamic shear strength of Dual Lock reclosable fastener SJ3552 (Type 170) to Dual Lock reclosable fastener SJ3551 (Type 400) is 20 lbs F /sq inch (138 kNewtons/m 2 )
and Dual Lock reclosable fastener SJ3550 (Type 250) to Dual Lock reclosable fastener SJ3550 (Type 250) is 36 lbs F /sq inch (249 kNewtons/m 2 ).
Engaged thickness is measured with a 1/2" diameter pressure foot with a 34 gram weight and will decrease if a load is applied or increase if a separation force is applied.
Cycle Life is the number of cycles (openings and closings) that the fastener is subjected to while maintaining 50% or greater of the original peel values.
Shelf life is from date of manufacture when stored in original packaging at 60° to 80°F (16° to 27°C) and 40 to 60% relative humidity.
