Effect of phenolic resin structure on the bonding properties of nitrile Rubber-Based Adhesives
Journal of Adhesion Science and Technology, 2020Co-Authors: P. Santhana Gopala Krishnan, N. Venkatesan, K. AdhinarayananAbstract:Three phenolic resins were used to study the effect of resin structure and its percentage content on the bonding properties of nitrile Rubber-Based Adhesives. The phenolic resins studied are derived from phenol, resorcinol and para-t-butyl phenol, and are of novalac type. These resins were characterized by infra-red and thermal studies. Several formulations were prepared by varying the phenolic resin/nitrile rubber ratio and these formulations were tested for viscosity and bonding properties. At a given resin-to-rubber ratio, the viscosity for resorcinol-formaldehyde resin was higher than phenol-formaldehyde resin followed by para-t-butyl phenol-formaldehyde resin. The peel strength of nitrile Rubber-Based Adhesive prepared from resorcinol-formaldehyde resin was higher than Adhesives that from para-t-butyl phenol-formaldehyde resin followed by phenol-formaldehyde resin. The lap shear strength of nitrile Rubber-Based Adhesive containing para-t-butyl phenol-formaldehyde resin was higher than of Adhesives co...

The Effect of Silica on the Peel Adhesion of Epoxidized Natural Rubber-Based Adhesive Containing Coumarone-Indene Resin
Polymer-plastics Technology and Engineering, 2010Co-Authors: Imran KhanAbstract:The peel strength of silica filled on two grades of epoxidized natural rubber (ENR), i.e., ENR 25 and ENR 50 Adhesive were investigated using coumarone-indene as the tackifying resin. Toluene was used as the solvent throughout the study. Result shows that peel strength increases with increase in silica loading due to the concentration effect of the filler. Peel strength, however, shows maximum value at 40 phr silica for both ENR 25 and ENR 50 an observation that is attributed to the maximum wettability and compatibility of Adhesive on the substrate.

Using FTIR spectral response signals to separate, characterize and quantify the effects of silicone or Rubber-Based Adhesive materials on microsphere lens enhanced MWIR SLS photo detectors
2017 IEEE National Aerospace and Electronics Conference (NAECON), 2017Co-Authors: D. B. Megherbi, P. Mack, J. Dizoglio, M. I. Vakil, N. Limberopoulos, A. UrbasAbstract:In our prior work we have analyzed, proposed global performance metrics, and shown how MWIR microsphere lens-enhanced single detectors have exhibited an increase in detector sensitivity and reduction in Noise to Signal Ratio (NSR). We have shown that, in general, the microsphere lens reduces the detector NSR independently of the increase in the enhanced detector sensitivity. We have also shown how microsphere lens material absorptions and misalignments can affect and reduce the microsphere lens-enhanced MWIR detector sensitivity. When placing a microsphere lens on a photo-detector, usually an optical silicone-or rubber Adhesive is used to adhere and hold the microsphere lens on the single photo-detector. In this paper, we present a novel hybrid model-based and experimental data driven-based technique for analysis and characterization of the effect of the Adhesive material on microsphere-lens-enhanced SLS single photo-detector sensitivity. In this work these Adhesive material characteristics are modeled and compared to experimental microsphere-enhanced single detector FTIR spectral data. As we demonstrate here, based on the data considered, the results show that the Adhesive material appears to adversely affect and decrease the detector overall sensitivity, and in some instances, by more than 40% depending on the Adhesive material index of refraction, even with a high Adhesive material transmittance/transparency.
