01-BK-41 Black Epoxy Topcoat (also referred to as 01-BK-041F) is a chemically cured, two-component, high solids epoxy topcoat for use on aircraft and aerospace equipment.
When used over properly applied commercial or military primers, it provides excellent adhesion and flexibility. It also provides excellent chemical resistance to solvents and immersion in hydraulic fluids, lubricating oils and water.
01-BK-041F is Volatile organic hazardous air pollutants-free (VOHAP-free), with a VOC < 340 g/l (2.8 pounds/gallon), and rated up to 121 ± 3°C (250 ± 5°F).
Product Compatibility: 01F Series is compatible with the following primer specifications:MIL-DTL-53022, MIL-DTL-53030, MIL-PRF-23377 + MIL-PRF-85582
Note: PPG Aerospace recommends you check the most recent specification QPLs for updated information.
Surface Preparation and Pretreatment: Apply over clean, dry, intact primed surfaces.
Mix ratio (by volume): 01F Series (base component) 3 parts : 80X109F (catalyst component) 1 part
Instructions for Use: Thoroughly stir or shake the base component (Part A) before combining to ensure all solids are completely dispersed. Add one volume of catalyst component (Part B) to the
three parts of base component (Part A). Do not use the catalyst component (Part B) from another color. Mix by hand stirring, paint shaker or mechanical mixing to ensure the base/catalyst mixture is homogeneous. Do not shake or mechanically mix material for longer than 10 minutes. Thinner is not required for the mixed material. If the addition of a thinner is necessary, MIL-T-81772B Type II* (IS-237) is available. Do not add thinner to attempt to compensate for coatings beyond its useful pot life.
Note: Use only if needed and if local and state VOC limits allow
Note: It is important to condition the paint for 24 hours prior to mixing by placing all materials in the shop or hangar, with ambient temperatures between 13° and 35°C (55° to 95°F). The minimum temperature of the paint components should be 13°C (55°F) prior to mixing.
Safety Precautions: Comply with all local safety, disposal and transportation regulations. Check the Safety Data Sheet (SDS) and label of the individual products carefully before using the products. SDS’s are available on request.
