3M 7010382221 Loop Fastener 1 Inch X 50 Yd White SJ3523

Product Description

The 3M 7010382221 is a plasticizer resistant nylon loop fastener supplied on a 1 inch wide by 50 yard roll, designed for demanding indoor fastening applications where standard hook-and-loop systems break down due to plasticizer migration. The loop material is backed with a plasticizer resistant PSA acrylic adhesive on a clear 3.5 mil polyethylene film liner. Engaged thickness is 3.1 mm. The adhesive system delivers high surface energy (HSE) and low surface energy (LSE) performance, bonding reliably to paint, bare and painted metal, glass, sealed wood, and many plastics. Licensed tradespeople and production technicians who need a clean, reliable peel-and-stick loop fastener for plasticizer-rich environments will find this format practical for high-volume use.

This fastener is designed for indoor use across a wide range of light industrial, commercial, and specialty assembly applications. It performs in environments where conventional acrylic adhesives fail due to plasticizer migration from flexible vinyl, foam, or similar substrates. The roll format suits both bench-cut and automated tape application workflows. Typical install scenarios include panel attachment, signage, interior trim fastening, and equipment mounting where a removable or repositionable connection is needed. Medium temperature performance makes it suitable for climate-controlled interiors.

Key Features

• Plasticizer resistant nylon loop construction prevents adhesive breakdown in vinyl-rich or plasticizer-heavy environments
• Plasticizer resistant PSA acrylic adhesive on a 3.5 mil clear polyethylene film liner
• 3.1 mm engaged thickness when mated with compatible hook fastener
• Bonds to high and low surface energy substrates including painted metal, glass, sealed wood, and many plastics
• Medium temperature performance rated for indoor climate-controlled environments
• Roll format: 1 inch wide by 50 yards, minimizing splice points and waste in production settings

Compatibility

Designed to mate with 3M SJ3522 hook fastener. This loop fastener (SJ3523) is intended for indoor fastening systems requiring plasticizer resistance and is sold as part of the 3M Scotchmate and SJ-series reclosable fastener family.

Installation Notes

Surface preparation is critical before application: clean bonding surfaces with an appropriate solvent to remove oils, dust, and contaminants, then allow to dry completely before peeling the liner and applying the fastener strip. Apply firm pressure across the full length of the strip to ensure full adhesive contact. This product is rated for indoor use only — do not install in wet, submerged, or high-humidity exterior environments. Allow adequate dwell time after application before loading the fastener joint.
