SurTec 650 chromitAL 铝材的非六价铬钝化
SurTec 650 chromitAL
电子、汽车和航空航天工业中铝材的非六价铬钝化

SurTec 650 chromitAL® is a chromium(VI)-free trivalent passivation for aluminium. The liquid concentrate delivers an excellent corrosion protection, comparable with the corrosion protection of a hexavalent passivation.

SurTec 650 chromitAL® is suitable for alloyed and casted aluminium and pretreatment before laquering, powder coating and gluing. It is easy to handle in immersion, spray and wipe application and produces an iridescent, faintly blue to tan and visible layer.

SurTec 650 chromitAL® meets or exceeds MIL-DTL-81706 and MIL 5541 for bare corrosion (336 h in NSS per ASTM B-117, respectively, DIN 50021 SS) and has a low contact resistance (< 0.8 mOhm/cm2). It is also heat resistant up to 100 °C (212 °F) with minimal loss in corrosion resistance.
US-patents 6,375,726; 6,511,532; 6,521,029; 6,527,841 are applied.

• 基于NAVAIR专利
• 多个主机厂认证
• 符合甚至超过MIL-DTL-81706和MIL-DTL5541的耐腐蚀标准
• 低电阻率,很好的用于电子行业(< 32,25 mOhm * m2))
• 符合航空航天业对裸露表面的高防腐要求(> 336小时NSS)
