Plyophen 23-900 and 23-057, two phenolic adhesives widely used in self-lubricating bearing applications, are being replaced with Plyophen 23-900X and 23-057X. The proposed alternatives are supposedly no different from the original adhesives since the change was made in the choice of catalyst used and then later removed during processing. A program was developed in which the basic material characteristics such as the chemical, mechanical, physical and thermal properties of the original adhesives are evaluated and compared with those of the proposed alternatives. The study includes floating roller peel test, Fourier transform infrared analysis, single lap shear test, thermomechanical analysis and viscosity measurements. Although this is an interim report, results so far indicate that there are definite differences between the original adhesives and the proposed alternatives.
