POLYMETAC allows bonding of metal and resins by a special surface processing proprietary process. In addition to its superior bonding strength, POLYMETAC technology allows significant weight reduction and reduction in component number thereby contributing to easier and simpler manufacturing processes.

Mitsui Chemicals is expanding business development for applications of the strong bonding technology and has received high marks from customers for uses in electrical and electronic segments such as those related to smartphones and automotive applications.

Demand for luxury metal housing applications in the smartphone market has grown significantly, especially in China. As metal housing requires bonding of metal and resin parts, continued good growth is expected in surface processing technology markets.

The investment in Sentronic’s subsidiary, which has a good foothold in China, will bolster Mitsui Chemicals’ expansion of POLYMETAC surface processing applications in the Chinese smartphone market.
