Protection and Aesthetic Enhancement for Your Parts
Black Oxide and Bluing provide cost-effective corrosion protection.
With our PRESTO BLACK and TRU TEMP product lines, a sealed finish is achieved that withstands up to 1,200 hours in humidity testing, ensuring superior durability.
Our processes are fast and versatile. TRU TEMP operates at 200°F, ideal for iron and steel, while PRESTO BLACK works at room temperature, perfect for heat-sensitive materials. Both methods process parts within 20–30 minutes.
These treatments not only protect but also enhance the appearance of your parts. They are the ideal solution for automotive, tooling, and machinery industries, delivering a professional and durable finish.
Types of Black Oxide Processes
Hot Immersion Black Oxide
- Step 1: Degreasing
- Parts are cleaned by ultrasonic washing using the compound SAFE SCRUB, diluted in water, for 5 minutes.
- Step 2: Rinse
- Rinse with water to remove residues and prevent contamination of subsequent baths.
- Step 3: Activation
- Parts are activated by immersion in a solution of OXYPRIME, diluted in water, for 10 minutes.
- Step 4: Rinse
- A second water rinse is performed to remove drag-out from the previous bath.
- Step 5: Black Oxide
- Parts are immersed in TRU TEMP 2nd Gen, heated to 96 °C, for 20 minutes.
- Step 6: Rinse
- A final rinse with water removes excess blackening solution.
- Step 7: Sealing
- Parts are immersed in DRI TOUCH IRP-3 for 20 seconds. This sealant penetrates the surface and evaporates, leaving a protective layer against oxidation.
Cold Immersion Black Oxide
- Step 1: Degreasing
- Parts are ultrasonically cleaned with SAFE SCRUB, diluted in water, for 5 minutes.
- Step 2: Rinse
- Rinse with water for 20 seconds to remove residues.
- Step 3: Activation
- Activation by immersion in SAFE PREP, prepared at 20% in water, for 3 minutes.
- Step 4: Rinse
- Rinse with water for 20 seconds.
- Step 5: Black Oxide
- Immersion in PRESTO BLACK MKP, prepared at 20% in water, for 5 minutes.
- Step 6: Rinse
- Rinse with water for 20 seconds.
- Step 7: Sealing
- Application of DRI TOUCH IRP-3 by immersion for 20 seconds, followed by natural draining.
Cold Brush-On Black Oxide
- Step 1: Degreasing
- Parts are degreased by ultrasonic cleaning using SAFE SCRUB, diluted in water, for 5 minutes.
- Step 2: Rinse
- Rinse with water for 20 seconds.
- Step 3: Black Oxide Application
- Manual application of BST-4 (used at 100%) with a brush onto the surface. Multiple coats are applied until the desired finish is achieved.
- Step 4: Rinse
- Light rinse with water for 20 seconds to remove non-adhered excess.
- Step 5: Sealing
- Parts are immersed in DRI TOUCH IRP-3 for 20 seconds and allowed to drain to seal the surface.
