Technical Data:

Description:

CitriSurf 8310 is a high quality blend of chemicals formulated for severe rust removal, descaling, and passivation of stainless steel products. It is provided in a high viscosity form for easy application on weld joints, vertical surfaces, and other large items or areas that cannot be conveniently dipped in a bath. CitriSurf 8310 is specifically designed to provide low cost and efficient removal of all rust and free iron from the surface of stainless steel and other metals, providing the highest chrome oxide levels possible.

Application Procedure:

To assure best results, the parts to be treated should be thoroughly cleaned to remove dirt, oils, and grease with an appropriate cleaning solution prior to treatment with CitriSurf.

All equipment, mixers, applicators or pumps should be clean and dry prior to use. Only containersPassivation Process constructed of polypropylene, polyethylene, or other acid resistant plastic or stainless steel should be used to hold or store this product.

Depending on the product being cleaned and passivated, polished, or brightened, dilution of the CitriSurf 8310 with water may be advantageous or necessary to slow down the reaction rate or lower the viscosity. Time, temperature and concentration of the product should be tested prior to use in production. For more aggressive cleaning or rust removal, longer times, higher temperature and concentration are advantageous. Please contact the manufacturer for assistance if necessary to determine the best formula and conditions for your product. Each application is different!

Prior to use, mix thoroughly by shaking or stirring. CitriSurf 8310 should be applied liberally to the surface to be treated with a sprayer, brush or roller. Coverage is approximately 250 square feet per gallon. Wait approximately 10 to 30 minutes, depending on the application, and then rinse the product from the surface completely. Repeat process if needed to obtain desired results. Difficult rust or corrosion must be tested to determine the exact best conditions for removal. If heavy rust needs to be removed, Scotch Brite (TM) or other non iron containing abrasive may be helpful.

Note: CitriSurf 8310 must remain moist during the treatment period. When using CitriSurf 8310 in direct sunlight or other hot environments, it may be necessary to periodically sprinkle the surface lightly with water to keep the CitriSurf from drying.

Rinse thoroughly with clean water and dry completely in air immediately or proceed with post-treatment to obtain the desired results. Drying can be accelerated by use of a hot air oven or other drying medium such as an air blower (hair dryer) to attain a clean, dry surface prior to post treatment or packaging.

Notes on Use:

CitriSurf 8050 is a Phosphoric Acid and Citric Acid based material, and as such it may cause irritation to exposed surfaces of the body. See Material Safety Data Sheet before using this material. Rubber or plastic gloves should be worn to apply the product to the surface or to wipe it dry.
Do not apply CitriSurf 2310 to electrical wiring or other conductive material that is connected to electrical current without first turning off all electricity! CitriSurf is a water based conductive material. Serious injury or death con occur from electrical shock.
Do not leave concrete exposed to CitriSurf for any period of time. Damage to concrete will occur with prolonged exposure.

Disposal:

Dispose of according to all federal, state and local regulations.

Storage:

CitriSurf 8310 should be stored at temperatures between 50°F and 120°F in 316 stainless steel or approved plastic containers (polyethylene or polypropylene). (If accidentally frozen, thawing will return product to normal.)
