Best Practices for 3M SJ3560
-
Design
As a general rule, four square inches of fastener area per pound 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.
-
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.
Note: Be sure to follow all government regulations and the manufacturer’s precautions and directions for use when using solvents or other cleaning methods.
-
Application
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. 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.
After the substrate has been cleaned and dried, the liner is removed from the fastener’s adhesive and without touching the adhesive, the fastener’s adhesive is applied to the surface using light finger pressure. The fastener is rolled down, to increase contact of the adhesive with the substrate’s surface, by one of two methods. Extra care must be exercised when rolling down 3M™Dual Lock™Reclosable Fasteners to prevent bending of the stems which can compromise the closure strength. The following methods allow adequate pressure to be applied to the Dual Lock without damaging the stems.
The first method uses a hand roller, with the wheel covered with a Type 170 Dual Lock reclosable fastener such as 3M™Dual Lock™Reclosable Fastener SJ3542. The Dual Lock covered roller is rolled, three times in each direction, over the Dual Lock attached to the substrate.
The second method consists of engaging a strip of plainback Dual Lock Type 170, such as 3M™Dual Lock™Reclosable Fasteners SJ3442 or SJ3742 to the previously attached adhesive backed Dual Lock. A rubber roller, with no Dual Lock on the roller is rolled over the backside of the plainback material. This will engage the two Dual Lock pieces. After rolling down three times in each direction, the strip of plainback Dual Lock can be removed and used to roll down the next piece of Dual Lock in a similar manner.
-
Curing
The pressure-sensitive adhesive bonds to the substrate on contact and parts can be handled immediately. Adhesive bond strength increases with time, pressure and temperature. A minimum of twenty four hours dwell time is recommended before applying a load or disengaging assembled parts. Recommended time to achieve maximum bond strength is 72 hours.
