Abstract: Weldable adhesive compositions that dampen noise or vibration are described. In addition, various tape products that include the adhesive compositions are described. Also described are various methods of damping noise or vibration by use of the adhesive compositions and tapes. In addition, vibration damping assemblies utilizing the adhesives are described.

Abstract: A method of hydrogenating a halosilane comprises: contacting a halosilane having the formula HaSiX(4-a), wherein a has a value of 0 to 4, and each X is independently a halogen atom and wherein if a is 0, the halosilane further comprises a hydrogen source, with a catalyst composition comprising at least two different metals, wherein the at least two different metals are selected from Cu and one of Co, Fe, Ni, and Pd; wherein the ratio of Cu to the second metal in the catalyst composition is 90:10 to 10:90; wherein the contacting is conducted at a temperature sufficient to hydrogenate a halosilane; and wherein an increase in the amount of halosilane hydrogenated is observed as compared to a method with a catalyst composition comprising one metal at the same overall loading of metal in the catalyst composition.
