Surface Preparation for Dual-Lock Fastener Application

Application Techniques Surfaces must be smooth, thoroughly cleaned and free of oil, surface contamination, and dry. In some exceptional cases (contamination by mold release, rough or porous surfaces, etc.) it may be necessary to sand or lightly abrade the surface. It is recommended the substrate be cleaned with a solvent such as Isopropyl Alcohol/water solution (50/50) and allowed to dry before the application of fastener.

Note: When using solvents, be sure to follow the manufacturer's precautions and directions for use when handling such materials.

Apply when fastener and surface temperatures are above 68ºF (20ºC). Remove protective liner (avoid contamination of adhesive) and apply with uniform, firm pressure for intimate surface contact to the substrate. Allow 72 hours dwell for maximum bond strength prior to testing or stressing the adhesive bond. Improved resistance to edge peel can be provided by recessing the Dual-Lock or by rounding the corners.
