Summary
Table of Contents

This review has been written as a practical approach to bonding various kinds of elastomers to substrates such as steel and plastics, as used in the manufacture of diverse products such as rubber covered rolls, urethane fork lift wheels, rubber lining for chemical storage or solid rocket motors, engine bushes and mounts, seals for transmissions, electrical power connectors and military tank track pads.

There are over 20 kinds of elastomeric polymer each having unique physical and chemical resistance characteristics. Through compounding, a given elastomer’s performance can be enhanced but no single elastomer can be compounded to meet all applications. In the same manner, no single adhesive can provide the needed levels of adhesion and environmental resistance to all polymers. Even when bonding a particular elastomer, the adhesive of choice can vary depending upon the compounding of the rubber including the cure system, the environmental application of the bonded assembly, the substrate to which the rubber is going to be bonded, the moulding method and the geometry of the part. Other factors affecting adhesive selection might include colour, conductivity, and means of application.

This review is based on the authors' years of experience working closely with end-use customers and offers a thorough overview of how to successfully bond rubber to a given substrate in the manufacture of quality rubber engineered components:

He holds a BS in Chemistry from Fordham University and a Ph.D. in Chemistry from Princeton University, where he was a DuPont Senior Fellow. His areas of expertise include materials and processes for electronic applications, primarily for high-reliability systems, hybrid microcircuits, printed wiring circuits, and other interconnect packaging technologies. He is an expert on polymeric materials including adhesives, coatings, encapsulants, insulation, reliability based on failure modes and mechanisms. Dr. Licari has had a forty-year career dedicated to the study and advancement of microelectronic materials and processes. Notable achievements throughout this career include conducting the first studies on the reliability and use of die-attach adhesives for microcircuits, which he did in the mid-1970s through the early 1980s, making industry and the government aware of the degrading effects of trace amounts of ionic contaminants in epoxy resins. He conducted early exploratory development on the use of non-noble metal (Cu) thick-film conductor pastes for thick-film ceramic circuits. He carried out the first studies on the use of Parylene as a dielectric and passivation coating for MOS devices and as a particle immobilizer for hybrid microcircuits. He developed the first photo-definable thick-film conductor and resistor pastes that were the forerunners of DuPont’s Fodel process, for which he received a patent was granted in England. And he developed the first photocurable epoxy coating using cationic photoinitiation by employing a diazonium salt as the catalytic agent (U.S. 3205157).

He holds a BS in Chemistry from Fordham University and a Ph.D. in Chemistry from Princeton University, where he was a DuPont Senior Fellow. His areas of expertise include materials and processes for electronic applications, primarily for high-reliability systems, hybrid microcircuits, printed wiring circuits, and other interconnect packaging technologies. He is an expert on polymeric materials including adhesives, coatings, encapsulants, insulation, reliability based on failure modes and mechanisms. Dr. Licari has had a forty-year career dedicated to the study and advancement of microelectronic materials and processes. Notable achievements throughout this career include conducting the first studies on the reliability and use of die-attach adhesives for microcircuits, which he did in the mid-1970s through the early 1980s, making industry and the government aware of the degrading effects of trace amounts of ionic contaminants in epoxy resins. He conducted early exploratory development on the use of non-noble metal (Cu) thick-film conductor pastes for thick-film ceramic circuits. He carried out the first studies on the use of Parylene as a dielectric and passivation coating for MOS devices and as a particle immobilizer for hybrid microcircuits. He developed the first photo-definable thick-film conductor and resistor pastes that were the forerunners of DuPont’s Fodel process, for which he received a patent was granted in England. And he developed the first photocurable epoxy coating using cationic photoinitiation by employing a diazonium salt as the catalytic agent (U.S. 3205157). The work was referenced as pioneering work in a review article by J.V. Crivello “The Discovery and Development of Onium Salt Cationic Photoinitiators,” J.
