For example, silver can be added to attain conductivity, quartz fillers can be added to improve impact resistance. Epoxies generally out-perform most other resin types in terms of mechanical properties and resistance to environmental degradation. As with any other product, it’s important to read the manufacturers label before making your selection. It is a good idea to clean the surfaces with methylated spirit or cellulose thinners and to roughen the surfaces before applying. Unibond Epoxy Re;pair Plastic will bond plastic to a wide variety of materials including leather, metal, glass, ceramics and most woods.

The raw materials for epoxy resin production are today largely petroleum derived, although some plant derived sources are now becoming commercially available (e. A product comprising more repeating units ( n = 2 to 30) is at room temperature a colourless solid, which is correspondingly referred to as solid epoxy resin. Change in color, known as yellowing, is a common phenomenon for epoxy materials and is often of concern in art and conservation applications. Will bond plastic* to a wide variety of materials including leather, metal, glass, ceramics, and most woods. When cured, the epoxy resin leads to a thermosetting plastic with high chemical resistance and low water absorption.

These resins do however contain hydroxyl groups throughout the backbone, which may also undergo other cross-linking reactions, e.

One downside of high purity liquid grades is their tendency to form crystalline solids due to their highly regular structure, which then require melting to enable processing.Plunge out the desired amount of resin and hardener onto a disposable surface and mix well for 60 seconds, or time indicated by manufacturer. When the two component parts – the resin and the hardener – are mixed together, they create a strong, waterproof bond that can be used to make long-lasting repairs on all kinds of plastic items. This class also displays lower viscosity at room temperature, but offers significantly higher temperature resistance than the aliphatic epoxy diluents.
