Everyone knows the protective agent, but it is very confusing, what is the copper protectant. Copper protectant refers to SL-362 environmentally friendly copper alloy passivation solution, which adopts Japanese high-tech R&D technology; environmentally friendly, chromium-free passivation solution specially developed for copper and copper alloy products; weakly alkaline formula, suitable for various Type of copper passivation, anti-rust treatment; anti-salt spray test time is long, does not affect the conductivity.
SL-362 environmentally friendly copper alloy passivation solution adopts Japan High-tech R&D technology; environmentally friendly, chromium-free passivation solution specially developed for copper and copper alloy products; weakly alkaline formula, suitable for various types of copper passivation, rust prevention Treatment; anti-salt spray test time is long, does not affect the conductivity; it is the choice between copper product process or final corrosion inhibition, rust prevention.
1. It is suitable for corrosion inhibition and rust prevention between processes of copper, purple steel, white copper, bronze, brass and other workpieces.
2, long salt spray anti-rust performance (according to ASTM B-117 and DIN EN SIO 9227 neutral salt spray test standards, 360H or more began to rust spots, but due to different material properties, the corrosion effect may be different) With the use of copper polishing products, the effect is better.
3. After passivation, the surface appearance, color, gloss, size, etc. of the workpiece are not changed, and the conductive properties of the product are not affected.
4, environmental protection, no chromium, non-toxic; in line with RoHS and the latest EU REACH specifications; does not contain hexavalent chromium components such as chromate.
5, the ratio of water to water is high, can be diluted 10 to 50 times, long service life, low unit cost, economical and practical.
6, easy to operate, easy to use; no complicated equipment, soak at room temperature.7, passivation solution is a stable agent, will not decompose, does not precipitate, easy to transport, long storage time, with the use.
1. Widely used in passivation and anti-rust treatment in the fields of precision electronics, precision instruments, aerospace, mobile communications, chassis cabinets, power copper bars, crystal crystals, etc.
2, used in copper, copper, power copper, crystal crystal, precision terminals and other products.
1. The passivation solution does not contain harmful substances, and is in compliance with RoHS and REACH environmental protection specifications. It has been tested by SGS.2. The wastewater is neutralized after treatment and has no impact on the environment.
The copper protectant product is a copper protectant for water-soluble chemically immersible copper and its alloys. Applicable to copper, brass, phosphor bronze, acid copper, alkali copper, copper alloy plating surface anti-tarnish and anti-oxidation, copper protective agent is relatively simple to operate, easy to use. Does not affect the conductivity. It is the most corrosion-resistant and rust-proof option in copper products.
