Best Practices for 3M Dual Lock Reclosable Fastener SJ3542
-
Surface Preparation
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.
The substrate surface should be cleaned to remove any surface contaminants with an appropriate cleaning method for the customer’s substrate, type and quantity of surface contaminants that need to be removed.
-
Application
Ease of Assembly: Dual Lock fasteners can be used to attach components before they enter the final assembly plant, reducing the number of parts and the assembly time. No tools are required.
Attachment Methods: The wide varieties of Dual Lock fasteners allow a design engineer exibility to be able use and attach Dual Lock to just about any substrate or application. Peel and stick pressure sensitive adhesive backed is quick and easy yet strong and secure. Non-woven backed can be used with a variety of adhesive choices such as hot melt, liquid, epoxies, sealants, etc. We have parts that can be attached with a screw or rivet
rigid and plain backed for developing your own special device.
