Paint, Carbon &
Phosphate Removers
|
 |
 |
 |
For removing all types of paints, varnishes, resins, and most other organic coatings including those with high resistance to chemicals such as baked epoxies and certain isocyanates. For removing carbon deposits, as from DETACHED carburetors and similar metal objects.
Apply by methods shown. Keep surface wet until coating is removed, or liquefied, or wrinkled. Time required may be as little as 5 minutes, rarely more than 30 minutes. Some products can be used hot as heat increases effectiveness and reduces time needed. Remove any residue with stiff brush or scraper or steel wool, or by rinsing with water or suitable solvent such as mineral spirits or turpentine, or by any combination of methods that are needed. If water is used, hotter is better, a suitable detergent may improve performance and a pressure washer or steam cleaner may help. To prevent rust on iron and steel, hot water improves evaporation. For assured rust prevention use hot water and a combination detergent/rust preventive like Metalterj #1520, page B1, or a suitable Rust Inhibitors, page B7. Products shown below with "ammonia odor" contain ammonia. Ammonia helps removal and its odor is a built-in warning against inhalation.
Cardisolvs
Removers called "Cardisolvs" are harmless to all metals and stone-like materials such as concrete and ceramics. Wood is usually slightly fuzzy after paint is removed, especially if water-rinsed. To minimize sanding, use as little water as possible. These products are harmful to most plastics; test before using on plastics and apparent wood veneers -- some apparent wood veneers -- some apparent veneers are plastic. THICK LIQUIDS -- For Use By Paint-On -- These Products Cling To Vertical Surfaces.
Superblend Plus
Use cold. Use full strength. An effective product for removing the raw components of coatings by paint-on. Intended as a pre-solv or for dry coatings. Contains no chlorinated solvents, alcohols, or ammonia. Colorless, flash point 150F, pleasant odor; details on request.
THIN LIQUIDS -- For Use By Immersion Or Recirculation Or Vaporization
Cardisolv #MBAO
Use cold or hot. Use full strength. Use #MBAO only when other removers have proved ineffective -- #MBAO is very expensive. Use hot if necessary, up to 190F. Evaporation is not a problem. Colorless, flash point 199F, boil point 395F, TLV is above vapor saturation point, evaporates slower than water; details on request.
Stripper #5250
Use cold or hot. Use full strength. Harmless to steel, stainless steel, and stone-like materials such as concrete and ceramics. DO NOT USE ON ALUMINUM. Test before using on other soft metals or on any surface that might be harmed by strong alkali.
Superblend
Use cold or hot. Use full strength. Use hot, if necessary, to 140F. Evaporation is not a problem. Colorless, flash point 150F, boil point 336F, evaporates slower than water; details on request.
General Guide
Some paints, varnishes and organic coatings can be removed from metals using a mixture of a detergent and a solvent. A general quide and alternate products and methods follow:

Where "All" includes aluminum and other soft metals and alloys; "Hard" includes iron, steel, stainless steel, and other hard metals and alloys such as copper, brass, bronze.
In general:
- Solvents are usually harmless to metals, wood and stone-like surfaces such as concrete and ceramics. Solvents may harm plastics.
- Depending on the metal, a suitable detergent can be chosen which will not harm the metal. Detergents are usually harmless to plastics and stone-like surfaces; detergents usually damage wood; detergents may separate veneers.
- Immersion or recirculation is faster than paint-on or vaporization.

Paint Stripper
Cardite HD
An extremely concentrated liquid alkaline cleaner designed for heavy duty spray and dip applications. Cardite HD is capable of stripping all types of resins and paints, including e-coat without the need of tank side accelerators. However for the most stubborn applications, or where process times need to expedited, the use of our tank side accelerator, "Cardite PS-2 Accelerator" is recommended. Cardite HD is not recommended for non-ferrous metals.
Packaging: • Drum, Tote, Bulk |

Zinc Phosphate and Lube Strippers
Metalterj #5150
A highly concentrated liquid alkaline cleaner specifically designed for heavy duty spray and dip applications. Metalterj #5150 is highly recommended for use in stripping zinc phosphate and lube coatings, providing rapid penetration and dispersal of coatings, and extended bath life. Metalterj #5150 is not recommended for non-ferrous metals.
