A continuous method for producing moisture curable hot melt adhesive compositions includes feeding a molten mixture of an organopolysiloxane, silicone resin, silane crosslinker, catalyst and solvent into an extruder and removing the volatiles. By using a continuous process it is possible to control the non-volatile content and produce a consistent product. Upon exposure to moisture the holt melt adhesive composition cures resulting in adhesion between two substrates.
