Main features
- Reclosable Loop Fastening
- Acrylic PSA Installation
- Configurable Roll Conversion
Product Description
3M Loop Fastener SJ3571 is an adhesive-backed woven nylon loop fastener for reclosable attachments used with a compatible 3M hook fastener. The soft napped loops engage the hook side for repeated opening and closing, while the acrylic pressure-sensitive adhesive mounts the loop to clean prepared surfaces without separate sewing or liquid adhesive. SJ3571 is commonly paired with 3M Hook Fastener SJ3572 and is available in multiple colors, widths, and roll lengths. Its preshrunk construction supports flat installation, and the adhesive is rated for long-term exposure to 93 deg C. The loop side is not a complete fastening system by itself.
Key features
- Reclosable loop function: Engages a compatible hook fastener for repeated access without screws, snaps, or zippers.
- Acrylic PSA attachment: Supports manual or automated mounting to clean, prepared surfaces.
- Configurable roll formats: Color, width, and roll-length options support conversion into application-specific pieces.
Applications
Applications include reclosable attachment of furniture cushions, signs, point-of-purchase displays, panels, and general industrial components.
