3M Dual Lock SJ3560 1in x 6ft Clear Reclosable Fastener - Strong Hold

In this review the 3M Dual Lock SJ3560 1in x 6ft clear reclosable fastener is evaluated as a practical alternative to mechanical fasteners for both workshop and home use. The bottom line: it is best for anyone who needs a strong, reclosable mounting solution that bonds to metals, plastics and glass without screws or rivets. The single biggest reason to buy is the dependable interlocking mushroom heads and acrylic adhesive that create a secure, audible snap and allow items to be opened and closed multiple times.

Key Features

• Reclosable interlock: Mushroom-shaped heads with about 250 stems per square inch provide a reliable interlocking connection that can be opened and closed repeatedly.
• Clear acrylic tape: The transparent conformable foam tape adheres cleanly to visible surfaces such as acrylic, polycarbonate and glass without obvious visual intrusion.
• Strong adhesive bond: The acrylic adhesive bonds well to painted metal, plastics and glass, reducing the need for mechanical mounting in many installations.
• Temperature resistance: The fastener maintains performance at elevated temperatures up to about 220F (104C), making it suitable for many indoor and some outdoor uses.
• Progressive strength build: Bonding attains roughly 50% strength at 20 minutes, about 90% at 24 hours and full strength after 72 hours, allowing staged handling after installation.
• Easy removal technique: Spraying alcohol on the tape softens the adhesive and makes clean removal simpler without aggressive scraping.

Who It's For

This product is ideal for hobbyists, installers and light industrial users who need a neat, removable attachment for panels, signs, trim pieces and display items where visible fasteners would be undesirable. It fits projects that require repeated access or repositioning because the Dual Lock can be opened and closed many times while holding firmly when mated.

Those who should look elsewhere include applications requiring structural load bearing for long spans or heavy suspended loads, and surfaces with very low surface energy where acrylic adhesives do not bond well. Also avoid using it where immediate full strength is required the moment of installation, since full bond develops over 72 hours.

Pros & Cons

Pros

• Durable interlocking mechanism provides a secure, audible snap verifying closure.
• Clear, conformable foam tape bonds cleanly to plastics, metals and glass with minimal visual impact.
• High quality adhesive and good temperature tolerance make it usable in a range of indoor and many outdoor situations.
• Removable with alcohol spray for cleaner peel-off compared with aggressive adhesives.

Cons

• Does not reach full adhesive strength instantly; requires up to 72 hours to achieve maximum bond.
• Not intended for heavy structural loads where mechanical fasteners are required.

Frequently Asked Questions

Can this tape be used outdoors?
Yes, it tolerates elevated temperatures and can be used outdoors in many situations, but exposure conditions vary so test for long-term outdoor exposure.

How soon can the bonded parts be handled?
Handle gently after initial bonding; about 50% strength is reached at 20 minutes, 90% at 24 hours and full strength after 72 hours.

How do you remove the tape cleanly?
Spraying alcohol on the tape softens the adhesive and makes peeling off much easier; clean the surface first before applying.
