- Alodine - is a chemical treatment process for aluminum used to provide corrosion protection and surface preparation for paint and adhesives. Alodine is an excellent treatment method for paint or adhesives since it greatly enhances the product's ability to form a bond with the aluminum.
- Anodize w/masking (multiple colors) - Sulfuric acid anodizing can provide comparable corrosion resistance and better wear characteristics than chromic acid anodizing. This type of anodizing is used in many architectural applications including windows and door frames, siding, decorative panels, railings, light poles and automotive trim. The coating is frequently colored for decorative purposes using organic dyes or metallic salts. Because of its low cost, this coating is commonly specified on many engineered aluminum components requiring protection from minimum wear and corrosion.
- Anodizing Hardcoat requiring unique masking - Wear resistance is the most frequent reason for specifying Hardcoat Anodizing. However, because Hardcoat is also highly dielectric, it is often used to insulate assembly components. Corrosion resistance is a third reason for using Hardcoat. At normal film thickness of 0.002", the coating offers corrosion protection superior to that of other anodic coatings, especially when it is sealed.
- Black Oxide - Achieve the blackest possible finish with maximum corrosion protection and abrasion resistance. For use on steel, zinc, stainless steel, copper, cast and malleable irons.
- Cadmium Plating - A single additive cyanide cadmium brightener with tremendous throwing power that produces a smooth ductile deposit, with an exceptional white brilliance that approaches silver plating in appearance.
- CARC Painting - The military established painting operations in Saudi Arabia to paint vehicles tan with so-called chemical agent resistant coating (CARC) paint. CARC is a polyurethane paint that provides superior durability, extends service life for military vehicles and equipment, provides surfaces with superior resistance to chemical warfare agent penetration, and greatly simplifies decontamination.
- Chemical Film- Chemical film coating is also referred to as Chem Film, Chromate Conversion, Iridite and Alodine. These are essentially the same process, the application of a chromate conversion coating on aluminum. Chem film coating produces a finish which:
- protects from corrosion;
- assures good paint adhesion; and
- conducts electricity.
- Dry Film Lubricant - Superb for use as dry, low friction coatings to reduce wear and prevent galling and seizure. Covers the surface with a solid, long lasting lubricating film that is capable of withstanding load and environmental extremes. Solid film lubricants have a wide and useful temperature range from 350° F to over 1000° F and their load carrying ability is high. Solid films can conduct electricity or be used as insulators. They are clean lubricants, do not attract dust or dirt, and are not diluted or washed from surfaces by water or most solvents.
- Electroless Nickel - Yielding excellent wear and corrosion resistance, electroless nickel is an autocatalytic plating process resulting in a reflective layer of nickel-phosphorous. The total build up plating process provides uniformity on all surfaces, making post machining unnecessary when dimensions are accurate. Offers surface treatments to increase hardness, lubricity and corrosion resistance.
- Electropolishing - Electropolishing uses a combination of rectified current and a blended chemical electrolyte bath to remove flaws from the surface of a metal part. Once the process is completed, the part is run through a series of cleaning and drying steps to remove clinging electrolyte. The resultant surface is clean and bright.
- Fluorocarbon – Fluorocarbon coatings can extend the life of moving parts; maintain the purity of pharmaceuticals and chemicals; insure perfect molded parts; reduce maintenance and downtime; produce uniform baked goods; reduce the possibility of electrical shock; improve the performance of medical instruments.
- Hard Chrome - Hard chrome plating is used for superior abrasion and wear resistance. Hard chrome plating has been one of the most widely used plating processes. With a 72 RC hardness rating, we recommend hard chrome to anyone looking for exceptional durability and abrasion resistance.
- Hardcoat Anodize w/Teflon Impregnation - Some industrial applications of Hardcoat anodizing include highly intricate parts such as pistons, anti-lock brake assemblies, pump components, valves, sliding parts, insulation plates and transmission parts.
- Manganese Phosphate - Has excellent corrosion resistance, and provides superior lubrication for metal to metal contact. Manganese phosphate coatings are generally heavier and coarser than zinc. The sacrificial finish has excellent break-in properties and reduces wear on moving surfaces. It prevents scoring and galling on moving parts. The absorptive coating retains oils, rust preventives and lubricants.
- MIL-SPEC Painting – We provide services for most Military-Specification painting and finishes. These specifications are constantly changing so call us to discuss your specific application.
- Passivation - Improves the corrosion resistance properties of components made of precipitation-hardened, austenitic, ferritic and martensitic steels. Passivation treatments improve the surface condition of stainless steel by dissolving iron that has been imbedded in the surface during forming or machining. If allowed to remain, the iron can corrode and give the appearance of rust spots on the stainless steel. Passivation, which consists of immersing stainless steel components in a solution of nitric or citric acid without oxidizing salts, will dissolve the imbedded iron and restore the original corrosion-resistant surface by forming a thin, transparent oxide film.
- Powder Coating- No matter what it is that you want to protect, powder coating is the right choice. Some advantages of powder coating are:
- Durability - Powder coatings are extremely durable, and various types are are formulated to endure the severities of chemicals, abrasion and chipping, or ultraviolet radiation from sunlight.
- Finish variety - The latest paint technology has resulted in texture, wrinkle, hammer-tone as well as smooth film powder coatings in any level of gloss.
- Color variety - Powder coatings are available in a wide array of colors, and can
be specially matched on request. - Higher quality - Before baking, parts painted with liquid paint have a strong tendency to attract dust particles that mar the final finish. Because powder coatings are dry before baking, they attract virtually no dust, leading to a better quality finish.
- Thermal Cycling - Thermal Cycling is a temperature modulation process developed to improve the performance, strength and longevity of aluminum.
- Zinc Cobalt - Inorganic Zinc coating when applied to blasted steel provides excellent corrosion protection, weathering protection, and very good resistance to salt water and solvents.
- Zinc Phosphate - Phosphate coating is a crystalline conversion coating that is formed on a ferrous metal substrate. The phosphating process relies on the basic pickling reaction that occurs on the metal substrate when the process solution comes in contact with the metal. This coating is employed for the purpose of pretreatment prior to painting, increasing corrosion protection, and improving friction properties of sliding components. In other instances, phophate coating is applied to threaded parts and top coated with oil to add anti-galling and rust inhibiting characteristics.
- Zinc with Chromate - Zinc electroplating is a soft, ductile, decorative, corrosion-resistant finish. Unlike most other commonly plated metals, zinc protects the substrate. The protection is accomplished by sacrificing itself. The zinc corrodes before the base metal thereby protecting the base metal. For additional corrosion protection, chromates are applied over the zinc. Chromates used in the zinc electroplating process become a component of the coating. Chromate films (available in multiple colors) are typically very thin, and the chromate coating provides no measurable thickness to the overall coating.
