Applications: Structural wood bonding methods have been used to construct loadbearing structs. for both indoor and outdoor applications, e.g. boat building. Resorcinol or resorcinol-formal- dehyde prepolymers can be used as accelerating compounds for curing phenolic resins. The addition of 3-10% permits shorter curing cycles in particle board and grinding wheel production. Resorcinol formaldehyde resins are curable under neutral conditions enabling the adhesives to be used with acid-sensitive systems such as fibre-reduced cement. Shaped refractory products can be made using resorcinol resins by a cold-mixing technique. Resorcinol formaldehyde resoles are used as tyre-cord adhesives and as high performance binders for wood composites

Resorcinol formaldehyde (RF) is a thermoset resin that is similar to PF, but has stronger adhesion and greater moisture resistance. It is, however, extremely expensive to process. The benefits of RF are not sufficient to warrant the added expense. Occasionally, RF is mixed with PF to form a phenol–resorcinol–formaldehyde (PRF) resin. See Figure 5.10.

Resorcinol-formaldehyde (RF) resin is a granular condensation product of resorcinol and formaldehyde.[37] It was commercially made by Boulder Scientific Company (Boulder, Colorado). The condensed RF resin is ground to the desired mesh size and has the appearance of broken glass with angular edges and smooth surfaces in a variety of sizes and shapes. Compared to CS-100 resin, RF resin improved Cs capacity by an order of magnitude under alkaline conditions.
