  • Best Practices for 3M SJ4570

    *See Terms of Use Below

    1. Design

      As a general rule, four square inches of fastener area per pound (57.3 square centimeters per kilogram) 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

    2. Surface Preparation

      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 should be cleaned with an appropriate cleaning method for the customers substrate(s) and surface contaminant(s) and amount that need to be removed.

      NOTE: Be sure to follow the manufacturer’s precautions and directions for use when using solvents, or other cleaning method

    3. Application

      There are typically 6 different methods for attaching Dual Lock low profile reclosable fasteners to various surfaces. The most important technique for Dual Lock low profile reclosable fastener SJ4570 is summarized below. For complete details on techniques and options for attaching 3M™ Scotchmate™ or 3M™ Dual Lock™ Reclosable Fasteners please see the technical bulletin “Attachment of 3M™ Scotchmate™ and 3M™ Dual Lock™ Reclosable Fasteners.”

      Pressure Sensitive Adhesive attachment: The fasteners and substrate surfaces should have equilibrated for a minimum of 1 hour at temperatures of 68°F (20°C) or greater before application.

      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.

    4. Curing

      A minimum of twenty four (24) hours dwell is recommended before applying a load or disengaging. Recommended time to achieve maximum bond strength is 72 hours (3 days)

    5. Clean-Up

      The substrate should be cleaned with an appropriate cleaning method for the customers substrate(s) and surface contaminant(s) and amount that need to be removed.

      NOTE: Be sure to follow the manufacturer’s precautions and directions for use when using solvents, or other cleaning method.
