Cardolite is a leading producer of high performance cashew nutshell liquid based binder resins for use in the transportation and brake industries. These thermosetting resins are cross-linked with hexamine and are used to hold brake linings, pads, blocks, and belts together. Cashew based resins are perhaps the best of the modified phenolic types because they offer all of the desirable characteristics of a straight phenolic (impact resistance, flexibility, thermal stability) without the oil bleeding. This condition causes a decrease in the coefficient of friction.
Cardolite binder resins are offered in a wide range of viscosity, solids (special solvents or solvent-free), and modifications to suit different applications requirements. These resins can be used as binders for friction products in asbestos and non-asbestos rolled lining and calendered segments as well as heavy-duty blocks and rail applications. These resins are also useful in other applications such as a replacement for tong oil in brake belts, and tire bead filler.
