Foshan copper antioxidant

Foshan copper antioxidants (copper protective agent, copper antioxidants, copper protective agent, copper sealer) blocking agents, anti-oxidants, anti-oxidants, copper protection agents, anti-color, anti-oxidation, anti-oxidant copper, copper Anti-discoloration agent Product Description: HT copper protective agents are copper and copper alloy special protective agent, is a water-soluble process. Is a nano-technology products. This layer of colorless protecting agent in copper and copper alloy formed on the surface of the transparent film, a thickness of a few nanometers. It can prevent water, sea water, air, oxygen, hydrogen sulfide, sulfur dioxide, as well as some organic vapors workpiece erosion. Mainly used in the indoor environment is protected for copper and copper alloys. Process characteristics: 1. a water-soluble technology, safety and environmental protection; 2. Simple process operation. Simply clean the workpiece thoroughly immersed in the working fluid, can be effective in the surface protective film; 3. the film almost does not affect the welding performance and contact resistance of the copper layer, suitable for electronic components and circuit boards copper protective layer; erosion protection layer 4. The ammonia or cyanide, no protective effect; 5. protective film can withstand a temperature of 150 ℃ -200 ℃ bake 0.5-1 hours, protection is no performance degradation; 6. Treatment area Great, at least can handle 15-20 square meters per liter, the actual maximum reached 35 m2 / liter 7. The acid system compared to other systems better stability containing formic acid, caustic also smaller. 8. The product of environmental indicators: EU ROHS environmental standards process: HT copper protective agent operation is extremely simple, just concentrate diluted in pure water can be used. Process: copper - washing - washing - immersion protection agent (note the temperature and time, time is too short affect the protective effect, it does not matter too long) - water (very important) - washing - drying - Drying (temperature is not too high) - test storage Miss Liu: 15989966842 QQ: 3057891720 http://eqxiu.com/s/FAxP5u?
