flexible curing agent H-120
Abstract: The many types of flexible curing agent of epoxy resin, aliphatic amines are modified alicyclic amine, flexibility anhydride, flexible epoxy polymer curing agent class, I think of the curing agent synthesis of molecular design and development of flexible curing agent to toughened epoxy resin, epoxy curing can improve performance.
Key words: epoxy resin; flexible curing agent; toughening
Because of its strong epoxy adhesive, electrical insulation and excellent chemical stability and good processing properties and a series of excellent performance and is widely used in coatings, adhesives, electrical and electronics, civil engineering, composite materials. But the brittle epoxy curing, impact resistance, and poor weather hampered their application defects, it is necessary for toughening of epoxy resin to suit different application needs.
Toughening of epoxy resin developed rapidly in many ways, the effect is different. There are two ways to its essence: 1) the introduction of epoxy resin or curing agent in the manufacture of some chain flexibility flexible epoxy resin or curing agent; 2) add a certain amount of epoxy resin formulations with epoxy resin or curing toughening agent from the catalytic activity. Synthetic resin or added flexibility will need a permit to use active toughening modifier for epoxy resin curing agent and then modified to be cured. Process more complicated. Curing agent molecules through the design, development, flexible synthesis of modified epoxy resin curing agent to the method, can improve the toughness of cured epoxy, high resistance to cracking and other performance, while improving the process of using epoxy, gives the performance of the new epoxy curing, this method is increasingly by people of all ages.
