获得哑光表面的方法 Methods to Achive Matted Surfaces
? 添加二氧化硅类型的消光粉 Addition of silica type matting agent ? 添加填料 Addition of filler or extender ? 增加颜料体积浓度Increase pigment volume concentration ? 添加蜡或硬脂酸盐Addition of wax and stearate ? 不相容树脂的混合Combination of incompatible polymer (粉末涂料powder coating) ? 机械式是表面粗糙 Mechanical roughening of the surface, e.g engraving, coinage

消光粉的基本要求
Fundamental Requirements to be Satisfied by a Matting Agent
? 容易分散 Easy to disperse ? 良好的悬浮性 Good suspension behavior in liquid coating ? 适于大多数的涂料体系 Suitable to use in almost coating system ? 容易调整所要的光泽度 Easy adjust to desired degree of matting ? 对流变性的影响较小 Little influence on rheological properties ? 对涂膜的机械性和抗化学性没影响 Coating surface is not sensitive to mechanical and chemical stress ? 高透明度 High transparency of the coating ? 高稳定性 Good consistency ? 化学惰性 Chemical inert

需要哑光表面的原因
Why do we need Matt-finish Coatings?

安全 Safety ? 防眩光, 例如汽车仪表板,交通指标,隧道墙 面Anti-glare e.g car dashboard, traffic sign, tunnel wall ? 防滑,例如电动工具的手柄 Anti-slip, easy to grip e.g electrical tool handle 装饰 Decoration ? 增加视觉效果 Improve visual quality of surface ? 掩蔽基材表面缺陷 Cover imperfect of coating surface ? 掩饰基材的不平整 “Cover” unevenness of surface
