A gunnable adhesive composition includes a silicone resin and an organopolysiloxane, or a reaction product thereof; as well as a filler and a solvent. The silicone resin and the organopolysiloxane are present in amounts to provide a resin/polymer ratio ranging from 58% to 64%. The gunnable adhesive composition may be applied to low surface energy substrates at ambient temperatures without primer or other surface treatment. The gunnable adhesive composition and adhesive product thereof are useful in weather barrier applications, such as building wraps.
