3 Scotchmate™ Reclosable Fasteners SJ3530 and SJ3531 Nylon Hook and Loop Technical Data Product Description March, 2008 3M™ Scotchmate™ Reclosable Fasteners offer advanced closure alternatives to zippers, screws, snaps, hooks, bolts and more. They offer greater design flexibility, faster product assembly, smoother and cleaner exterior surfaces and improved product performance in many applications. The hook and loop fasteners consist of two strips of nylon fabric which engage to form a quick fastening attachment. Simply pull the strips apart by hand to disengage. The woven hook is covered with tiny, stiff hooks, about 300 hooks per square inch (46/sq. cm.). The woven loop is covered with thousands of soft, pliable napped loops, providing for thousands of openings and closings (cycles). The hook and loop are preshrunk to ensure maximum dimensional stability and flatness. These hook and loop fasteners are coated on the backside with an aggressive and tacky rubber based pressure sensitive adhesive designed to function over a range of temperatures and humidity. This permits these fasteners to be easily and conveniently attached to a variety of substrates.

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 of static load is suggested as a starting point for such evaluations. a) 3M™ Scotchmate™ Loop engaged to 3M™ Dual Lock™ Reclosable Fastener provides increased strength over standard reclosable fasteners. 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 sufficiently high to the substrate may cause the fastener to release from the substrate. b) 3M™ Scotchmate™ Reclosable Fasteners SJ3530, SJ3531 and 3M™ Dual Lock™ Reclosable Fastener SJ3540 are engaged with firm pressure and disengaged, peeled or cleaved at the rate of 12 inches (305 mm) per minute. The engaged thickness is dependent upon the direction and amount of applied load. c) Cycle Life is the number of cycles (openings and closings) that the fastener is subjected to while maintaining 50% or greater of the original tensile value. d) Shelf life is from date of manufacture when stored in original packaging at 72°F (21°C) and 50% relative humidity. e) Typical performance characteristics were measured under controlled laboratory conditions of 72°F (22°C) and 50% Relative Humidity. The user should evaluate products in the actual application to ensure suitable performance for the intended use before producing production quantities of materials. -2- 3M™ Scotchmate™ Reclosable Fasteners SJ3530 and SJ3531 Nylon Hook and Loop Additional Performance Characteristics Note: The following information is not product release requirements, nor product specifications. Rather this data represent typical performance using standard test methods. This is intended for use as a guide to assist in selection of 3M™ Scotchmate™ Reclosable Fasteners for further evaluation. Customer specifications should not be based solely on the data presented in this document. Solvent Resistance: The nylon components resist attack by most common solvents and alkaline solutions. Acid solutions may cause deterioration of the fastener. The adhesive on 3M™ Scotchmate™ Reclosable Fasteners SJ3530 and SJ3531 may be affected by many common laboratory solvents and transportation fluids (gasoline, motor oil, etc.). If solvent resistance is desired, it is suggested that the customer evaluate 3M™ Scotchmate™ Reclosable Fasteners SJ3571, SJ3572 or many of our 3M™ Dual Lock™ Reclosable Fastener products. Plasticizer Resistance: The adhesive on Scotchmate reclosable fasteners SJ3530 and SJ3531 may be affected by plasticizers found in many common flexible vinyls or other materials containing high levels of plasticizing materials. This may result in softening or loss of adhesion indicative of plasticizer migration. If plasticizer resistance is desired Scotchmate reclosable fasteners SJ3522 and SJ3523 or many of our reclosable fastener products can be evaluated. Flammability Resistance: If you need 3M™ Reclosable Fasteners to meet standard flammability tests (such as FAR 25.853, FMVSS-302, ASTM E-162, ASTM E-662, BSS-7239 and others), it is suggested that you refer to the publication 3M™ Scotchmate™ Reclosable Fasteners Flame Resistant Products Product Selection Guide (70-0707-3992-8). Resistance to Environmental Exposure: Temperature down to -20°F (-29°C) increases the typical closure strength. If products will be exposed to outdoor weathering or ultraviolet exposure then black is suggested and preferably 3M™ Scotchmate™ Reclosable Fasteners SJ3571, SJ3572, SJ3576, SJ3577 or many of our Dual Lock reclosable fastener products. Water (Humidity) Resistance: Closure strength of nylon hook and loop fasteners decreases after prolonged exposure to water due mainly to water absorption by the cut nylon ends for hook products. Closure strength is regained when dried. Improved water resistance of the closure can be obtained by using polyester hook and loop (3M™ Scotchmate™ Reclosable Fasteners SJ3576, SJ3577, SJ3586 or SJ3587) or our polyolefin based Dual Lock reclosable fasteners. Once bonded the adhesive has high resistance to moisture under typical use conditions. Volatile Outgassing: Volatile outgassing, as per ASTM E595, is one important test in determining the suitability of materials for spacecraft. Generally 3M reclosable fasteners with acrylic or no adhesive have lower volatile outgassing values. Scotchmate reclosable fastener SJ3530 and SJ3531 have not been tested for outgassing. Products tested at the Goddard Space Flight Center can be found at the following web site: http://outgassing.nasa.gov/ Sterilization/Autoclaving: Typically plainback 3M™ Scotchmate™ Reclosable Fasteners SJ3401 or SJ3402 can be gas or steam sterilized, or autoclaved with most common systems. Washing and Dry Cleaning: Plainback products sewn to fabrics will typically shrink less than 4% after washing or dry cleaning, unless the fabric has greater shrinkage amounts. -3- 3M™ Scotchmate™ Reclosable Fasteners SJ3530 and SJ3531 Nylon Hook and Loop Available Sizesa 3M™ Scotchmate™ Reclosable Fasteners SJ3530 (Hook) and SJ3531 (Loop) Standard Roll Selvedge Extended Widthsa Length Edgeb Linerb in. ± 1/16" (mm) ± 1.6 Yards (Meters) SJ 3530P (Hook) SJ 3531P (Loop) 1/2" (12.7 mm) 50 yds.

Attachment Techniques The following information is intended to assist the designer considering the use of 3M™ Scotchmate™ Reclosable Fasteners. Final product performance depends on actual conditions, including the fastener selected, the conditions in which the fastener is applied and the time and environmental conditions in which it is expected to perform. Because many of these factors are uniquely within the user’s knowledge and control, it is required that the user evaluate the 3M product to determine whether it is fit for a particular purpose and suitable for the user’s method of application and desired end use. As a general rule, four square inches of fastener area per pound of static load to be supported is suggested as a starting point for evaluation. More or less area may be needed depending on specific conditions or end use applications. The most important techniques for attaching Scotchmate reclosable fasteners SJ3530 and SJ3531 are summarized below. For complete details on techniques and options for attaching reclosable fasteners please see the technical bulletin Attachment of 3M™ Scotchmate™ and Dual Lock™ Reclosable Fasteners. Pressure Sensitive Adhesive attachment: The fasteners and surfaces should have equilibrated for a minimum of 1 hour at temperatures of 68°F (20°C) or greater before application. Generally these adhesive backed fasteners should be applied to surfaces that are smooth, dry and free of oils, mold release agents or other surface contaminants. -4- 3M™ Scotchmate™ Reclosable Fasteners SJ3530 and SJ3531 Nylon Hook and Loop Attachment Techniques (continued) It is recommended to wipe the surface with a solvent such as isopropanol/water solution (50:50) and allow to dry. NOTE: Be sure to follow the manufacturer’s precautions and directions for use when using solvents. The liner is removed and without touching the adhesive, the fastener is applied to the surface using firm roller pressure to help ensure complete adhesive contact to the substrate. The pressure-sensitive adhesive bonds on contact and parts can be handled immediately. Adhesive bond strength increases with time, pressure and temperature. A minimum of one hour dwell is recommended before applying a load or disengaging. Recommended time to achieve maximum bond strength is 24 hours. Heat (Press) Bonding: 3M™ Scotchmate™ Reclosable Fasteners SJ3530 (Hook) and SJ3531 (Loop) can be attached to many fabric and foam articles by press bonding. The fastener is adhered to the article and bond strength is increased by applying heat and pressure for a given time period. Mechanical Attachment: The bond strength of Scotchmate reclosable fasteners SJ3530 and SJ3531 can be increased by mechanically attaching it to difficult to adhere to surfaces such as textured plastics and wood by using staples. Application Ideas Scotchmate reclosable fasteners SJ3530 and SJ3531 can provide a firm adhesive bond to a wide variety of surfaces, including, but not limited to those listed below. Because product performance will depend on actual conditions within any specific application, it is essential that the user evaluate the 3M product to determine whether it is fit for a particular material purpose and suitable for the user’s method of application.
