化學鍍錫光亮劑,化學鍍錫添加劑,化學鍍錫改善劑
    傳統化學鍍純錫、化學鍍錫合金都是以主鹽加絡合劑,用次亞磷酸鈉做還原劑,采用強酸環境下化學鍍錫或錫合金。鍍液對底材及鍍層有一定的腐蝕性,化學鍍錫或化學鍍錫合金會隨著鍍層加厚而結晶變得粗糙多孔,附著力變差,甚至鍍層脫落。加入化學鍍錫光亮劑可以使化學鍍錫層結晶更細致、致密、光亮。減輕化學鍍錫液對銅及銅合金底材及鍍層的腐蝕,增加化學鍍錫層外觀光亮性、附著力及耐蝕性。能鍍出優良的錫鍍層、錫合金鍍層。可用于各種傳統的氯化亞錫化學鍍錫、硫酸亞錫化學鍍錫、甲基磺酸亞錫化學鍍錫等酸性化學鍍錫及錫合金,也可用于四價錫堿性化學鍍錫,工件長時間化學鍍錫不易發暗、發灰,可鍍厚錫。可作為化學鍍鉛錫合金添加劑。
