Advanced Coating Solutions at MACHFINISH- Engineering Specifications:
Aluminum Pigmented Coatings
Our aluminum pigmented coatings are engineered to meet the stringent requirements of aerospace and military applications, initially specified under MIL-L-85614. These coatings are designed to provide superior galvanic protection for both threaded and non-threaded fasteners, adhering to NAS 4006 with an emphasis on durability and performance under extreme environmental conditions. Key properties include optimal adhesion, resistance to common aerospace fluids, and the ability to withstand temperatures up to 425°F without compromising the tempering temperature of the substrate material.
Solid Film Lubricants (Dry Film Lubricants)
MachFinish’s solid film lubricants are formulated to minimize friction in high-temperature environments, exceeding the capabilities of traditional liquid lubricants. Compliant with AS5272 and MIL-PRF-46010, these lubricants are essential for high-performance applications involving dynamic load and wear conditions. Specifications for each type are as follows:
• Type I: Rapid cure within 1 hour at temperatures between 275°F and 329°F, achieving a minimum endurance life of 250 minutes.
• Type II: Suitable for higher thermal conditions, curing within 1 hour at 375°F to 427°F with an endurance life of 450 minutes.
• Type III: Developed to meet low VOC requirements, offering flexible curing options while maintaining a wear life of 450 minutes under varied thermal conditions.
Epoxy Primers
Two (2) and three (3) part coatings are chemically activated and do not require heat or solvent evaporation to obtain a cured coating. In addition, these coatings contain a soluble chromate to meet corrosion resistance requirements.
MIL-PRF-23377 “Primer Coatings: Epoxy, High Solids”. This is a corrosion inhibiting, chemical and solvent resistant, solvent-borne, high-solids primer coatings that have a maximum volatile organic compound (VOC) content of 340 grams per liter (g/L) (2.8 pounds per gallon) as supplied by the manufactures.
Classification. The primer coatings are of the following types and classes.
Types:
Type I – Standard pigments
Type II – Low infrared reflective pigments
Classes:
Class C1 – Barium chromate-based corrosion inhibitors
Class C2 – Strontium chromate-based corrosion inhibitors
Class N – Non-chromate-based corrosion inhibitors.
MIL-PRF-85582 “Primer Coatings: Epoxy, Waterborne”. This is a corrosion inhibiting, chemical and solvent resistant, waterborne, epoxy primer coatings that have a maximum volatile organic compound (VOC) content of 340 grams per liter (g/L) (2.8 pounds per gallon) as supplied by the manufacturer. The classification and performance requirements of MIL-PRF-85582 are identical to MIL-PRF-23377.
BMS 10-11 “Chemical and Solvent Resistant Finish”
Classification. Primer coatings are of the following types, classes, and grades.
Types:
Type I – Primer
Type II – Epoxy Topcoat
Classes:
Class A – for spray application without electrostatic assist
Class B – for both spray and electrostatic assist spray application (No Class B primers have been qualified).
Grades:
Grade A – (primer or topcoat), 600 grams per liter OR MORE of VOC
Grade B – Solvent-borne Primer, 350 grams per liter OR LESS of VOC
Grade D – (High Solids Topcoat), 420 grams per liter OR LESS of VOC
Grade E – Water-Reducible Primer, 350 grams per liter OR LESS of VOC
Cetyl Alcohol (1-Hexadecanol) Solutions (AS87132)
Formulated for critical assembly applications, our cetyl alcohol solutions act as effective lubricants for various fastening devices. These solutions are particularly effective in preventing galling and ensuring consistent installation torque across a range of metal surfaces and coatings. Available in petroleum-based and water-based formulations, these lubricants are offered in grades optimized for specific applications:
• Grade A: Light lubrication for general fastening.
• Grade B: Medium concentration for robust applications including bolts and externally threaded parts.
• Grade C: High concentration for critical applications requiring heavy lubrication.
Each product line is developed with the precise needs of engineering professionals in mind, ensuring that every application not only meets but exceeds the technical requirements of the most demanding environments.
Intended Use:
Cetyl alcohol, also called hexadecanol, is a white, crystalline, odorless, and noncorrosive and is compatible with fats, fatty acids, waxes, and petroleum oils. It is soluble in light petroleum base solvents and water. Cetyl alcohol is a nontoxic, non-irritating, and otherwise innocuous material; however, when dissolved in a petroleum base solvent, care should be taken in handling and storage because of the relatively low flash point of the dissolved mixture, attributed to the petroleum base solvent. It is intended for use as a lubricating coating to promote the installation of fasteners as follows:
- Grade A: Collars, nuts, and washers.
- Grade B: Pins, bolts, externally threaded parts, and noninterference fit fasteners.
- Grade C: Interference fit fasteners, internally threaded parts, and parts requiring heavy lubricant coating.
