Carbonbuster: Advanced Carburizing Stop-Off Paint for Heat Treatment Processes

Carbonbuster is an innovative, water-soluble carburizing stop-off paint designed to prevent unwanted carbon absorption during gas carburizing and carbonitriding processes. As a high-performance masking paint, Carbonbuster provides exceptional protection while maintaining ease of removal, making it an essential solution for industries that require precise surface hardening control.

What is Carburizing and Why Use Stop-Off Paint?

Carburizing is a heat treatment process where iron or steel absorbs carbon at high temperatures to enhance hardness, strength, and wear resistance. This process is widely used in automotive, aerospace, medical, firearms, and manufacturing industries to improve the longevity and performance of metal components. However, in applications where selective hardening is necessary, a carburizing stop-off paint is applied to designated areas to prevent carbon penetration.

Key Benefits of Carbonbuster

Superior Protection: Effectively blocks carbon diffusion in gas carburizing and carbonitriding applications.
Versatile Application: Can be used as a masking paint for carburizing, and carbonitriding processes.
Easy Washability: Ensures effortless removal post-treatment, reducing cleanup time.
Environmentally Friendly: Water-based formula with low burden on health and safety standards.
Compatible with Various Methods: Available in multiple formulations to accommodate different application techniques, including automatic machines, brush application, and vacuum carburizing processes.

How to use / Points to note

Usage

Degreasing

Before applying the CARBONBUSTER, degrease and clean the surface of the treated parts well to ensure that they are free of grease and dust.

Stirring

Stir evenly and thoroughly before use.

Application

Apply by a brush, dipping, or automatic machine with a viscosity that is easy to apply. To increase the stop-off effect, allow the surface to dry after the first application and then apply a second coat.

Dilution

If the viscosity is too high, or if water evaporates during use and the viscosity becomes high, adjust it to a level that is easy to apply using the dedicated diluent "CARBONBUSTER LIQUID".

Thickness

As a guide, the thickness of the coating film should be 0.3 to 1.5 mm.

Drying

Dry at room temperature for approximately 4 to 8 hours. Forced drying should be performed by natural drying for 1 to 2 hours after application, followed by forced drying with hot air or in a drying oven at a temperature of 70°C to 100°C.

Precautions after Drying

If the coated film is left for a long period of time after drying is complete, the film may absorb moisture, resulting in degrading stop-off performance. Therefore, process the parts as soon as possible after drying.

Removal

After carburizing, the coated film should be washed and removed with warm water at 70-90 C. In the case of warm water, it is recommended to wash the treated product with a few percent alkaline cleaning and rust inhibitor to prevent rusting. (We offer recommended products.) Remove CARBONBUSTER 600 with a wire, brush, or sandblasting.

Precautions

Handling

When handling the product, wear glasses, gloves, etc. and be careful not to allow droplets to adhere directly to your skin. If it gets on your skin, wash it immediately with water.

Eye Contact

Rinse eyes with clean water for at least 15 minutes and then seek immediate medical attention from an eye doctor.

Ingestion

Immediately spit out the product and seek medical attention. If the product remains in the mouth, gargle thoroughly with water.

Storage

Keep the container tightly sealed and stored indoors in a well-ventilated place out of direct sunlight. Avoid locations where temperatures fall below 0°C to avoid freezing.

Accidental Release

If the amount is small, wipe it off with a rag. If the amount is large, fill the area with dirt or sand to block the outflow and collect it in an empty container, etc.

Disposal

Disposal should be consigned as solid waste to a duly licensed industrial waste disposal contractor or local public agency that has the capacity to dispose of it. Containers should be disposed of after completely removing the paint inside.
