JEFFAMINE® SD-2001 amine is a difunctional secondary amine derived from JEFFAMINE® D-2000 amine.  JEFFAMINE® SD-2001 amine allows for better control of open time and curing speed in applications like polyurea  spray coatings, polyurea pre-polymers, and polyurea hybrid systems. 

JEFFAMINE® D-205 amine is similar in AHEW and structure to JEFFAMINE® D-230 amine. However, its primary  amines are more hindered, making it slower to react with epoxy groups. JEFFAMINE® D-205 amine is a good  choice for epoxy applications where longer open time and a low exotherm are highly desired.

Application

• Slower reactions with epoxy resins – more manageable large scale  composites, etc
