Starch glues or emulsion-based adhesives are used for gluing cigarette seams. It is a solvent for adhesives in aerosol glues that glue foam cushions together. Cyanoacrylate adhesives are sometimes known generically as instant glues, power glues or superglues. Some special fletching glues are primarily cyanoacrylate repackaged in special fletching glue kits. It glues well with epoxy resin or resorcinol adhesive. Rabbit-skin glue is more flexible when dry than typical hide glues. Modern waterproof glues, especially epoxy resin, have caused revolutionary changes in carvel and clinker construction. They are a component of accelerators for cyanoacrylate glues. Also, there are very few glues available specifically for gluing PP. BPS is also used as an anticorrosive agent in epoxy glues. With the development of high performance glues, interest has recently developed in adhesive bonding. Its chief use is as the main component of medical cyanoacrylate glues. It can be fastened with glues, screws, and nails. It bonds to most cured wood glues (except PVA). Joints with casein glues had detachment failures due to inherent stresses in the wood.
