Publication number: 20200354522Abstract: An imide composition obtainable by providing (a) reacting a dianhydride with a diamine in the presence of a solvent at a temperature in the range of from 20-80° C. The molar ratio of the dianhydride to the diamine is from 0.25-4, forming an imide precursor; and (b) subjecting the imide precursor as formed in step (a) in the presence of a solvent to a heat treatment carried out at a temperature from 80-150° C. to convert the imide precursor into an imide, thereby forming the imide composition. Also, a preservative composition including the present imide composition; a metal article having a coating that provides the present preservative composition; a process for preparing the imide composition; the use of the present imide composition to prevent and/or reduce false brinelling in a roll bearing system; and the use of the present preservative composition to prevent and/or reduce false brinelling in a roll bearing system.Type: ApplicationFiled: March 18, 2020Publication date: November 12, 2020Inventors: Amra Cenanovic, Frank Fiddelaers, Remko Thijssen, Albert van den Kommer, Roel van der Zwaan

Publication number: 20200354525Abstract: A liquid curable silicone elastomer composition is disclosed. The liquid curable silicone elastomer composition comprises an organopolysiloxane (A) containing at least two silicon-bonded alkenyl groups per molecule, an organopolysiloxane (B) containing at least three silicon-bonded hydrogen atoms per molecule, a platinum based catalyst (C), an inhibitor (D), and a silica filler (E). The organopolysiloxane (B) is a branched (or resinous) polymer, contains M siloxy units, and the at least three silicon-bonded hydrogen atoms are present on the M siloxy units. The inhibitor (D) is selected from the group consisting of acetylenic alcohols and their derivatives. The inhibitor (D) is present in the liquid curable silicone elastomer composition in an amount to provide a molar ratio—of the inhibitor (D) to platinum in the catalyst (C)—of from 150 to 900 (150:1 to 900:1).Type: ApplicationFiled: July 30, 2020Publication date: November 12, 2020Inventors: Patrick BEYER, Ivonne HANKAMMER, Hans Peter WOLF
