OlyBond500 is a two-component polyurethane adhesive used to adhere insulation board to insulation board. It is dispensed in 3/4 to 1-inch bands that spread to several inches while rising 3/4- to 1-inch above the substrate and can also be used to adhere a variety of board stocks to most roof substrates in both new and re-roof applications. Place the board stock into the adhesive and walk into place. A chemical cure takes place securing the board in approximately 4 to 8 minutes after application, depending on temperature and weather conditions.
