Anti-Smog

Item #: CH10-675 - 10 liter container
   
    Usage especially in chrome plating equipment for rotogravure cylinders with good electrolyte revolution. ANTI-SMOG is an additive to decrease the fumes of the chrometank while it is plating. It has no negative influence to the chrome quality itself. ANTI-SMOG prevents contamination of the chrome plating equipment, and its wetting agent effect eases the the cylinder rinse process. ANTI-SMOG provides for clean exhaust air and relieves the chrome separator as well as existing exhaust-wash out units (less chrome deposits in the drain water). It is possible to reduce the exhaust amount, depending on the exhaust system when using ANTI-SMOG. ANTI-SMOG also has a positive influence to the clean air environment in the chrome plating department.

    Hardening Additive

Item #: CH0-01-01 - 1 gallon container
   
    Hardening Additive can be used with higher temperatures and a higher current density (30-34 A/dm2. With this hardener, the hardness can be regulated and kept constant. It is primarily used where solution temperature can be held constant.

It is packed in a 1 gallon container, is concentrated and has a dilution ratio of 9:1.

    Hardening Additive - CHEMA 9

Item #: CHEMA9/2 - 1 gallon container
   
    Chema 9 is an additive that is used in copper electroplating baths with a current density (22-28 A/dm2. It produces a hard, semi-glossy but ductile copper deposit. With Chema 9 additive it is possible to reach a copper hardness of between 160 and 200 Vickers, depending on the quantity of additive used per A/h.

Due to excellent surface quality and extremely fine-grained copper structure, a minimum of mechanical treatment of the copper surface is required after plating. The use of Chema 9 gives a copper quality that is suitable for conventional etching and especially for electronic engraving.

The hardness of the copper remains constant, and recrystalization does not occur. If used according to specifications, there is no decomposition of the electrolyte due to Chema 9. This additive may be added with an automatic dosing unit.

It is packed in 1 gallon containers and is a concentrate. It has a dilution ratio of 9:1.
