Suggested Handling & Curing

126-49(SP)A/B is ready to use as supplied. Further thinning may be accomplished by adding small amounts of CMI 127-05 or Xylene. Prior to using, be certain to re-suspend silver. Good properties are achieved when cured for 60 minutes at 150°C but end user is advised to experimentally determine temperature and time best suited for individual applications. 126-49(SP)A/B is not recommended for applications that cannot cure below 100°C.
