Shenyang southeast Chemical Research Institute successfully developed t-111 tough epoxy curing agent

September 15, 2011

it is gradually limited to carbon fiber composites. The preparation and use of this kind of flame retardant [China paint information] following the development and production of T-99 flexible curing agent, Shenyang southeast Chemical Research Institute recently launched t-111 tough epoxy curing agent. When t-111 is used as an epoxy resin curing agent and directly cured with E-51, 127 epoxy resins (127 is 100 parts: t-111 is 60 parts), a cured product with an elongation at break close to 100% can be obtained, and the cured product shows the characteristics of toughness. The thermal deformation temperature is higher than 50 ℃

t-111 as an epoxy resin activity increasing sensor, the most important and longest failure is the use of overload toughener of experimental force, with less heat loss. It can be mixed with curing agents such as ether amine, aliphatic amine, alicyclic amine and aromatic amine, as well as accelerators and catalysts in different proportions, and different fracture can be adjusted. They use two different transverse zebra elongation and thermal deformation temperature. Increase toughness and impact resistance. T-111 is suitable for many occasions where epoxy resin is cured with amine below 110 ℃. T-111 epoxy resin curing agent has small odor, light color and low viscosity (less than 200mp. S). Participate in structural cross-linking reaction, light curing, homogeneous and transparent

t-111 the reaction speed at room temperature is very slow, and it needs to be heated in the later stage to cure completely. Therefore, the occasion of use is restricted. When it is slightly higher than room temperature, for example, the curing speed is accelerated at 40 ℃ and 60 ℃, and fast curing can be achieved at 100 ℃. According to China epoxy (China epoxy resin industry) experts, its scope of application includes: colorless transparent decorative adhesive; Toughening agent; compound material; Sealing materials; Impact resistant materials; Polyurea primer; Electronic encapsulation, etc. Shenyang southeast Chemical Research Institute:, email: sydnhg@
