Abstract: A fastening element (11) for hard constructional components such as, e.g., concrete, includes a cylindrical base body (12) having opposite first (14) and second (15) ends, a self-tapping thread (17) provided on the outer surface (16) of the base body (12), an inwardly located engagement element (18) for a setting bit, a receptacle opening (19) that opens toward the second end (15) facing in a direction opposite the setting direction of the fastening element (11) and that is provided with a load application, and a collar (21) provided at the second end (15) and extending radially outwardly.

Abstract: The invention is directed to a thermal addition curable solventless silicone release composition having a reduced coefficient of friction and improved slip characteristics. The invention is also directed to a method for producing a thermal addition curable solventless silicone release composition on a substrate by applying the thermal addition curable solventless release composition of the invention to a substrate and curing the coating on the substrate using heat. The invention is further directed to a thermal addition curable solventless silicone release coated article having a reduced coefficient of friction and improved slip characteristics.

Abstract: The invention is directed to a polymeric microparticle containing silicone release composition having improved slip/shear, anti-block, transfer, and lower release properties. The silicone release composition may be formed of thermal or radiation cured solventless silicone release compositions. The silicone release composition may also be formed of a UV-cationic silicone release composition. The polymeric microparticles are preferably polymeric microspheres. The invention is further directed to the use of such microparticle containing silicone release compositions to coat a substrate, and release coated substrates formed thereof.
