Large surface lamination is an assembly where two substrates of similar size are bonded together over a large shared surface area. The large surface reduces the stress at any given point, which can be an important factor in adhesive selection. A common example of this assembly is a cloth-covered foam seat cushion. This type of seat often has a contoured shape, so the fabric must wrap evenly without wrinkles, which may require repositioning during the assembly process. It doesn’t necessarily need a strong bond, but the bond should be even everywhere to prevent any separation through repeated use. While a low-viscosity liquid adhesive applied in thin repeating lines or roll-coated could work for some types of assemblies, in this case the porous fabric means a spray adhesive with good hold-out would be a better option. The evenly distributed stress over a large surface area also allows a broad range of adhesive choices depending on the particular substrates. Spray adhesives generally have better hold-out and are flexible enough to prevent dimpling in the final product. For our seat cushion example the porous fabric means a water-based spray adhesive such as 3M™ Fastbond™ is a good choice to consider. The pebble spray allows for an even distribution of adhesive onto the shaped foam surface, the adhesive has good repositionability during assembly and results in a soft non-dimpling glue line.
