摘要:
A process for preparing silica-based organic-inorganic hybrid resin using sol-gel process. Phenol is used as catalyst to reduce the gel time of the sol-gel process and cyclosiloxane is used as modifier to increase the toughness of the resultant inorganic-organic hybrid resin.
摘要:
The present invention discloses an epoxy resin composition with a non-halogen, non-phosphorus flame retardant, which comprises (a) 100 parts by weight of an epoxy resin; (b) 40-60 parts by weight of a phenolic novolac hardener; and (c) 5-60 parts by weight of a silica-novolac hybrid resin solution as a flame retardant.
摘要:
This invention discloses a method for manufacturing liquid crystal display pixel array, which is capable of promoting an aperture ratio. The method of this invention includes forming a gate metal layer on a glass substrate; forming a gate insulation layer; forming a semiconductor layer; forming a second metal layer on the semiconductor layer; forming a switch region photoresist layer and a data line region photoresist layer on the second metal layer; etching the second metal layer; etching the semiconductor layer; etching the switch region photoresist layer and the data line region photoresist layer; and etching edge portions of the semiconductor in the switch region and the data line region by using fluoride-bearing gas. To etch off more edge portions of the semiconductor in the data line region, according to this invention, the thickness of the data line region photoresist layer is made thinner when forming the photoresist layer.
