OFFSETS to HT424

HT-424® was designed as far back as the 1950's under an Air Force contract as a high performance, modified epoxy-phenolic film adhesive typically supplied on a glass carrier. It was developed for bonding metal-to-metal and sandwich composite structures requiring both short-term and long-term exposure to extreme temperatures.  The original formula has outstanding adaptability to many bonding procedures. Mako's updated formulation uses more benign chemistry and will still meet all the requirements of Federal Specification MMM-A-132 and Military Specification MIL-A-25463, Type II and Type III, just like the old HT424.

Original versions of HT424® film adhesive contained asbestos & had strong phenolic odors.  Mako's new formula features reduced odor, and improved OSHA standing with no phenol formaldehyde.  Mako's AF-1424 offset also has the ability to produce smaller batch sizes, with increased toughness. Furthermore, Mako's film adhesive offset to HT424® has meaningfully longer outlife versus the original formula's short 5 days.
