    • The present invention relates to an approach for improving the compatibility of antistatic agents and ceramer hardcoats so that such hardcoats can be provided with excellent antistatic characteristics. In particular, it has been discovered that the antistatic agents of this invention can be combined with aqueous sols of surface treated, colloidal inorganic oxide particles having a negative surface charge without destabilizing the negatively charged colloids. It has further been discovered that the combination of the antistatic agent and negatively charged, surface treated colloids of this invention interspersed in a cured ceramer matrix unexpectedly provides dramatic improvements in antistatic protection. The antistatic approach of this invention also provides excellent antistatic protection over a wide range of relative humidity, including conditions in which RH is below 40%, especially at 15% to 40% RH.
    • 本发明涉及一种改善抗静电剂和陶瓷单体硬涂层的相容性的方法,从而可提供这样的硬涂层具有优异的抗静电特性。 特别地,已经发现本发明的抗静电剂可以与具有负表面电荷的表面处理的胶态无机氧化物颗粒的水性溶胶结合,而不会使带负电荷的胶体不稳定。 进一步发现散布在固化的陶瓷基体中的本发明的抗静电剂和带负电的表面处理胶体的组合意外地提供了抗静电保护的显着改进。 本发明的抗静电方法还在宽范围的相对湿度下提供优异的抗静电保护,包括RH低于40%,特别是15%至40%RH的条件。
