Tableau Anti-Tarnish Lacquer, Easy to Use Spray Lacquer to Keep Bright Metals Including Silver, Copper and Brass Shiny. 200ml

Product Information

Clean using mild detergent and warm soapy water to remove dirt and debris. Use a clean soft cloth or sponge to wipe down. The other main constituent needed is of course, elbow grease. Good pressure is needed when polishing, since this actually smoothes over the ductile surface of the metal and helps to obtain the required mirror-finish. This is much more resistant to further tarnishing than the active surface left by a chemical cleaner. Residue in crevices should be washed out with a toothbrush and detergent before the final polish. Tips Although there are a number of suitable spray paint formulas that work well with copper pipes, we feel that the Rust-Oleum High Heat Spray Paint is the best option. Not only has the paint formula been optimised for use with metal and heat but it also looks very good once dry offering a great end result. For the best possible performance though you should try to keep the copper pipes as close to room temperature as possible until the spray paint has dried.

Epoxy Coatings. Epoxy coatings have excellent resistance to wear and chemicals. They are relatively expensive and are only available in thermosetting or two part (catalyst activated) compositions with relatively short pot lives. They are good for severe indoor applications, but they degrade rapidly and darken in a few months of exterior service. Discoloration of copper and its alloys also may occur at the curing temperatures normally recommended for thermoset coatings. It is wise to use low curing temperatures and short curing schedules to avoid such in-process discoloration. Catalytic activity by copper sometimes allows lower temperatures or shorter curing schedules to be used.If you're looking for a specific aesthetic, there are various styles and colours available that will match in with your interior. Lacquer is a protective coating, or ‘finish’. It is applied to the copper surface by brushing on multiple layers of liquid lacquer. Once each layer is dry, the next layer is added, often by hand, and this process continues until the lantern is covered in the depth of lacquer required for its setting. Before dealing with ways in which a good finish can be obtained and maintained, the point must be made that old copper that has acquired a patina with age may be best preserved by keeping the patina. Once centuries of patina have been cleaned off, that distinguished deep dull brown cannot be regained. For some items, the loss of a patina will reduce the perceived value significantly. Cleaning

Interestingly, it has been suggested that one way of getting a good patinated finish is to coat a well-cleaned item with simple cellulose lacquer not intended specifically for copper or brass. In time a good chocolate brown film is said to develop underneath the lacquer film. Presumably it helps if the surrounding atmosphere is humid, as in a conservatory. Proprietary Finishes The product is called KLEARPLAST V.O.C. STAY CLEAR WOOD FINISH. It's a new hybrid of acrylic lacquer and CAB (cellulose acetate butyrate) lacquer which is water clear (non-yellowing), has "excellent adhesion" and... this part surprised me as I read it... it can be applied over "brass and copper." If it performs as advertized... you could conceivably spray your entire piece of furniture... wood, copper and all, in one shot. They claim that it sands good and can be used as its own sealer too, which would be a time saver. Lacquer is not an especially porous material so lacquered copper lanterns can sometimes be more difficult and time consuming to clean. Lacquer doesn’t breathe well and so can trap moisture inside the lantern if it is left outdoors in humid environments for extended periods of time (i.e. during a rainstorm). My question are ; Since the set finishing is a bright-shinny copper or brass set out by the customer, how can we manage and what to apply appropriately to solve out those situation to offer the solution to last the Top Coat of a Clear or Matte Finished color where we are keen to have the long-last minimum of 5 years? Not only does this create a brilliant finish but it prevents further ageing of the metal therefore preserving the look and design created.

A combination of a silicone primer and an acrylic top coat displayed excellent appearance after more than six years of service in interior applications with moderate or no abrasion. The same system darkened significantly in one year of open exterior exposure but indicated good performance for more than three years on sheltered doors of office buildings and churches. Leveling Agents. Leveling agents improve the flow properties of coatings and thereby provide better surface appearance. In addition, the likelihood of Dinholing or other defects is reduced. Pencil Hardness - Hardness at which transition from scratching of the coating to crumbling of the lead occurs. The scale of hardness from hardest to softest is 7H, 6H, 5H, 4H, 3H, 2H, H, HB, F. Copper is a lesser-known finish and one which is really only looked at when you want a radiator that will stand out. We think the radiators in this range are tremendous for customers who are looking to fit a contemporary or commercial space. A. Dear Richard, The most ideal solution to your problem is a clear coat of electrophoretic lacquer (Cathodic). Varun Bhalla

Use as little or as much polish as you need - plenty of polish may be needed to cut through heavy tarnish easily. If only a little is used there is less to fill nooks and crannies. Coats: 1 coat is normally sufficient. If used on exterior objects, two or three coats is recommended. Drying Time: 2- 3 hours depending on temperature and humidity. Re-coating Time: 2- 3 hours depending on temperature and humidity.

Protecting Copper Gutters

The spraying area should be free of dust and dirt and at moderate temperature (between 50 and 900F), at low humidity (certainly less than 80% when organic vehicles are used), and well ventilated. If you want more durability and especially better adhesion... PPG has a line of water-reducible metal cleaners and conditioners that work well. Looking at my PPG product data sheet book I see that they spec out brass and copper in the same section as aluminum that is to be clear coated. Which is good because most of the metal cleaning and conditioning materials will change the physical appearance of the metal due to the strength of the acids used. Aluminum that is to be painted gets treated with a different cleaner and conditioner than does Aluminum that is to be clear coated. PPG recommends the application of their acrylic urethane (catalyzed) DAU 75 after having finished the metal cleaning and conditioning steps on brass, copper, and aluminum that is to be clear coated. Now... it does mention that this particular cleaning and conditioning process can be used on aluminum to keep that bright silver look without a clear coat over it. But... I don't know if it would produce a similiar tarnish resistant coating on copper or not. I would at least test it out to see if it might not. If so... that'd give you more options in terms of the finished look of your furniture. Also, the DAU 75 can be flattened down using the specified PPG flattener. If you go this route your local PPG jobber should be able to suppy you with all of the relevant PPG data sheets which will spell out precisely what you need to do. Silicone Coatings. Silicones provide the best potential for coatings which must operate at elevated temperatures. Thin films of these high-cost coatings are used and protection by a second coat of a more durable abrasion resistant lacquer may be necessary. Ultraviolet absorbing compounds are added to prevent darkening of the silicone during exterior exposures. This makes the various radiator paint formulas on the market great options for painting your copper pipes but as you may expect, some paint formulas perform much better than others. In our opinion, the best paint formula on the market for use on your copper pipes is Rust-Oleum Heat Protective Paint with it performing particularly well when used on copper pipes while also being available in one of the wides ranges of colors too. Urethane Coatings. Color degradation on exterior exposure has been a problem with urethane coatings. Resistance to chemicals and abrasion are good even for the air drying coatings.

Cleaning: On lacquered finished products use warm soapy water only with microfibre cloths. Do not use acidic or alkaline based products. Both of these finishes are shiny, smooth and not as durable as lacquered metal because they don’t have any protective coating on them like lacquers do. Polished and buffed finishes are popular for copper lanterns that are to be placed indoors. Some examples of coating performance indicate the range of serviceability of organic finishes on copper and its alloys. Chelating Agents. Benzotriazole and other chelating agents interact with copper and its alloys to prevent tarnishing. Chelating agents are preferentially absorbed on the surfaces of the metals and act as an invisible barrier to elements or compounds which might cause corrosion. In this way they protect the metal against oxidants permeating through the coating and continue to protect even after a minor defect has formed in the coating. Chelating agents may be included in the coating formulation or applied as part of a pretreatment procedure.The distinctive colors of copper and copper alloys make them prized for architectural and consumer items and objects of art. Their natural metallic tones range from reddish to silvery and a number of other colors can be obtained by chemical or electrochemical processing. Copper and its alloys are extremely resistant to corrosion, but a superficial discoloring tarnish eventually forms with exposure to the atmosphere or handling. The appearance of these metals can be preserved by applying thin clear protective coatings to their surfaces. These coatings are organic chemicals which harden at room temperature or with baking and are usually applied in a solvent vehicle. After fine polishing a precious item, the lifetime of the finish can be prolonged by handling only when wearing cotton gloves. This avoids the oily acidic coating on the skin causing fingerprint stains. Lacquering
