Sharp Develops New Corn-based Paint for LCD TV receiver


Sharp Corp. and Kansai Paint Co., Ltd. have jointly developed a paint derived mostly from cornstarch. The two companies facilitate the coating process by shortening the time required for the drying process compared to previous paints. The paint is used to finish the stand of new models “LC-52GX1W,” “LC-52GX2W,” “LC-46GX1W” and “LC-46GX2W” of “AQUOS,” Sharp’s LCD TV receiver line, which are manufactured at Sharp’s Kameyama plant no. 2 and slated for launch in October 2006.The newly-developed paint by Sharp Corp. and Kansai Paint Co., Ltd only consists of a base resin and a solvent. The base resin can be cured by the vaporization of the solvent. This is an improvement achieved by further modifying the esterified starch. Specifically, the new paint excludes a curing agent by adjusting the chain length of ester, optimizing a modified resin and selecting the optimum solvent.


The time required for bake-drying is reduced to 15 minutes in an environment at 50°C, which is half that of the previous plant-based resin paint. Coating performance has been improved while maintaining the durability, gloss and texture of the previous plant-based resin paint. As a result, the latest paint can be applied to a wider range of products. Sharp intends to use it on refrigerators, air conditioners, washing machines and other products.
