EMA toughening agent is can increase agent film flexibility property material 质. certain hot solid property resin agent, ring oxygen resin, aldehyde resin and saturated and polyester resin agent solid rear elongation low, property relatively large, bonding 部位承受 outer force very easy generate cracks, speed expand 展, 导致胶层 cracking, resistant fatigue, can as is structure bonding use.
  
EMA toughening agent 含 has active property 基团, can and resin chemical reaction, solid rear full versus 容, has also need separation versus, obtain relatively toughened 效果, make heat deflection temperature (HDT) or decline micro, impact resistant property can also obvious improvement. low separation liquid or is increase agent material add resin in, although can reduce property, rigid property, strong/high degree, heat deflection temperature (HDT) large degree decline, can meet/satisfy structure bonding requirements, therefore, increase agent and toughening agent is full different.

EMA toughening agent selection 原则:

（1） ring oxygen resin agent use selection liquid 体丁腈橡胶, 端羧基 liquid 体丁腈橡胶, poly 硫橡胶, liquid silicon 橡胶, polyether, polysulfone (PSU), polyimide (PI), nano carbon acid 钙, nano oxidation titanium and other.

（2）酚 aldehyde resin agent can selection 羧基丁腈橡胶, liquid 体丁腈橡胶, polyethylene (PE) alcohol shrink aldehyde, polyether 砜, polyphenylene oxide (PPO) ketone. water solvent property aldehyde resin 以羧基丁腈胶乳, polyethylene (PE) alcohol as toughening agent.

（3） fast solid acrylic ester structure agent selection acrylic ester 橡胶, 羧基丁腈橡胶, chlorine 丁橡胶, chlorine polyethylene (PE), ABS resin and other.

（4）氰基 acrylic ester agent selection acrylic ester 橡胶, ABS, SBS, SEBS and other.

（5）不 saturated and polyester resin agent selection liquid 体丁腈橡胶, polyethylene (PE) alcohol shrink aldehyde, poly acid ethylene and other.

（6）脲 aldehyde resin agent can selection poly acid ethylene emulsion, polyethylene (PE) alcohol and other.
