Room-temperature curing adhesives for structures



Methods by which synthetic adhesives can be cured at ambient temperatures are covered. The alkyl cyanoacrylates, epoxies, and MPL monomers can be cured, with little shrinkage, to obtain metal adhesive bonds which compare favorably to those obtained by high temperature modes of curing. An investigation by which novolac epoxies were rendered more flexible with accompanying increases in the temperature and salt spray resistance is described.
