Sharp Corp. and Kansai Paint Co. Ltd. have developed technology for painting the plastic parts of consumer electronics devices with plant-based resin paint made from corn starch. Kansai Paint holds the basic patent; both companies have applied for a usage patent.

Since 2004, Sharp and Kansai Paint have been developing plant-based resin paint with the aim of using it to coat products. The two companies have been working on fixation to materials and hardness of the paint film to improve durability, and on gloss and texture to improve quality and performance.

Compared to conventional paints that use petroleum and other fossil resources as their basic ingredient, plant-based resin paints can reduce global warming and thus environmental burden.

Plans are to use the plant-based resin paint first on the stand of AQUOS models released in the spring of 2006. The AQUOS cabinet already uses non-halogen resin, which has less environmental impact compared to conventional resin when the TV is disposed of.

This technology is being positioned as the second stage of biomass environmental technology, following technology for blending plant-based plastic and waste plastic. Sharp plans to apply this paint to more product types.
