LT  655   高耐蚀三价铬蓝白钝化液

                                                 ·  单剂型,操作范围广,PH范围宽,低温到常温均可操作;

                                                 · 钝化产品色泽均匀,放置不易发黄;

                                                 · 适用于所有镀锌工艺的后钝化处理;

                                                 · 特别适合处理大平面多孔位的工件，不易产生发黄现象;

                                                 · 耐高温性能好,在较高的温度下,可达到类似黄钝的抗腐蚀效果;

                                                 · 耐蚀性能极佳,锌酸盐工艺中,挂镀可达144小时无白锈,滚镀72小时无白锈;
