In order to design the best formula of epoxy adhesive and achieve the required bonding performance, it is necessary to understand the adhesion mechanism of epoxy adhesive and the failure mechanism of bonding. China has done a lot of research in this area and put forward many theories. Although there are still some deficiencies, many practical problems have been clarified and solved, which greatly promoted the development and application of epoxy adhesives. With regard to the basic principles of...

NEOPRENE is a synthetic rubber material designed to be flexible, durable, resilient, and very resistant to failure and breakdown by compression and water. Air and water become isolated in its unique molecular structure. Neoprene is temperately stable with a high heat resistance and commonly found in oven mitts. Its durable quality makes it very useful for applications such as shoe soles, seating, and acoustic noise blocking. Neoprene has comfortable qualities that make it desirable for wet...

Epoxy resin is a general term for compounds that contain two or more epoxy groups in a molecule and form a three-way cross-linked structure in the presence of a suitable chemical aid such as a curing agent. It is a thermosetting resin with good bonding performance, corrosion resistance, and high electrical insulation and mechanical strength. It has many excellent properties. It has good bonding effect on metal and non-metal, so epoxy resin is called "all-purpose adhesive". Two major discoveries...
