《K303》电接触固体薄膜润滑剂是一种把润滑剂与金属缓蚀剂相结合的新型产品。该润滑剂无毒、无味,在一般的环境中不分解、不吸潮、不吸尘、不产生有害气体,可长期存放。该润滑剂和固体金属有极强的附着力,在正压力不变的情况下,使金属间的摩擦系数减小83～91%,该润滑剂抗潮和抗腐蚀性能好; The “K303” electric contact solid film lubricant is a new product that combines a lubricant with a metal corrosion inhibitor. The lubricant non-toxic, tasteless, do not break down in the general environment, does not absorb moisture, do not vacuum, does not produce harmful gases, long-term storage. The lubricant and the solid metal have strong adhesion, under the condition of constant pressure, the friction coefficient between the metal is reduced by 83-91%, and the lubricant has good moisture resistance and corrosion resistance;
