#581 Foam & Fabric Spray Adhesive

#581 has been on the market for almost 20 years and has become the accepted standard for quality and performance when bonding polyethylene and other flexible foams to themselves or other substrates.  #581 offers a “controlled lace” spray pattern that helps eliminate overspray which occurs with most other aerosol adhesives.  This spray pattern allows the user to see exactly where the adhesive is going and how much is being applied.  #581 has relative good heat resistance – upwards of 175°F.  How long should I wait before making the bond?  Pretty simple test; after spraying the surface, wait a couple minutes.  Touch the sprayed surface.  If the adhesive transfers to your fingers – WAIT.  If it feels sticky, but doesn’t transfer to your fingers, MAKE THE BOND!  Be certain you’ve indexed (aligned) both pieces before making the bond.  Once the two pieces touch, they’re “forever”.  Trying to separate them will result in destruction of one or both substrates.
