DESCRIPTION
A chemical Brighting prepration for polishing product, RXSOL RC 4100 is a mixture of concentrated inorganic acid for brightening and chemically polishing , Aluminium,copper and copper based alloys. It is an acid form ulation containing surfactant,suppressant and inhibitor for chemical poli shing (bright dipping) of most non ferou alloys. This formulation is widely used commercially. RXSOL RC 4100 contains additives to reduce nitrogen oxide fumes and to enhance the brightening ability.
APPLICATION
- Brightening and chemically polishing of copper alloy components such as fasteners, valves, and wire.
- Prepare surface for electroplating
- Deoxidize copper alloys
USE AND DOSE
Use as received to immerse and agitate the parts for 1 – 3 minutes, depending on the condition of the parts before dipping and the desired results. Before dipping, parts should preferably be as chemically clean as before electroplating, but degreasing is adequate, although some shortening of bath life may be expected. Temperature should be kept below 90F for best results. For heavy production, some form of cooling may be required.
Following the dip, rinsing must be thorough to remove the viscous acids remaining on the parts.For subsequent electroplating or water-dip lacquering, no further treatment is required. If the parts are to be dried, a further dip in Quik-Dri 1000 will insure spot free drying and will aid in the tarnish prevention.
CONTROL
Control of RXSOL RC 4100 is generally visual. Excessively long dip times or lack of brightening indicate the solution is losing strength. Drag-out should be replaced with full strength RXSOL RC 4100. For longer life, drag-out should be controlled by adequate draining before rinsing, and drag-in of water should be kept at a minimum.
EQUIPMENT
Tanks should be of stainless steel (304, 316, 317, & 347) PVC, stoneware or lined with polypropylene. Stainless steel baskets or containers and adequate ventilation are recommended.
PHYSICAL PROPERTIES :
Appearance – Transparent Liquid
Sp. Gr. At 25 C – 1.3 to 1.4

FEATURES AND BENEFITS
- Excellent polishing and smoothing action
- Long use life provided water drag-in is kept to a minimum
- Slow rate of metal removal
- Contains no chromic acid
- Less fuming than sulfuric/nitric bright dips
- No residual passive film to inhibit electroplating
- Used at room temperature
CAUTION
RXSOL RC 4100 is a mixture of concentrated acids with Inhibitor and wetting agents and the normal safety precautions for handling such acids apply. Avoid skin, eye and oral contact. Wear protective clothing, gloves and goggles when handling the product. Flush exposed areas immediately with clean, cold water. Contact a doctor immediately in case of injury.
WASTE DISPOSAL
Discharge to a disposal system. In order to be completely informed on the latest regulations for your area, please contact the local authorities.
The precipitated metallic salts should be treated as hazardous waste.
