Abstract: A dynamic mixer (40) comprising a rotatable structure (10, 111, 11, 1, 2, 3, 4, 5) having a cylindrical base (14) having a connector disposed at one end, an opposing thinned end, flights of 3 to 6 blades (11, 12, 151, 61), separated by a notches (13, 18) the blades (11, 12, 151, 61) have an inlet face facing the connector end, an outlet (30) face facing the thinned end, a leading edge (21) facing the direction of rotation, a trailing edge (20) opposite the leading edge (21), a standard leading face (154, 65) which tapers from the leading edge (21) to the outlet (30) face and a standard trailing face (166) which tapers from the trailing edge (20) to the inlet face, or a reverse leading face (154, 65) which tapers from the leading edge (21) to the inlet face and a reverse trailing face (155, 66) which tapers from the trailing edge (20) to the outlet (30) face, the notches (13, 18) are offset from one another and the article is adapted for use in a dynamic mixer (40) to mix viscous material when rotated in the m

Abstract: A one part moisture curable adhesive composition having improved heat stability is comprised of a silyl terminated polymer, a catalyst and a particular phosphite compound. The phosphite compound has three groups wherein at least two of the groups are aryl groups, but preferably all three of the groups are aryl groups. The one part moisture curable adhesive composition is useful in severe applications such as solar panels and automotive and building window glass.
