280°C Short Term Heat Resistance Conductive Formula Multi Metal Repair BPO Polyester Putty Industrial Powder Coating
JLTL BPO 280°C High Temperature Conductive Body Filler is a specialized industrial repair putty for manufacturers and powder-coating factories that need to repair metal surface defects before electrostatic powder spraying and high-temperature baking.
Unlike ordinary automotive body filler, this product is positioned specifically around the requirements of industrial powder coating, combining high-temperature resistance, conductive performance, multi-metal adhesion, filling capability and sanding performance.
It is suitable for steel, phosphated steel, aluminum alloy, stainless steel and other metal components used in machinery, electrical cabinets, metal furniture, hardware, automotive components and industrial equipment.
If the repaired workpiece will later enter a powder-coating oven, selecting a conventional body filler simply because it has good filling performance may not be sufficient.
The complete production process may be:
Metal Part
→ Surface Preparation
→ Defect Repair
→ Sanding
→ Electrostatic Powder Spraying
→ High-Temperature Baking
The filler therefore needs to remain suitable during the subsequent high-temperature process.
JLTL BPO 280°C High Temperature Conductive Body Filler is developed specifically for this type of workflow.
The product is designed for applications where the repaired metal part will undergo high-temperature powder-coating baking.
It provides a higher temperature capability than conventional fillers intended primarily for normal automotive refinishing.
Potential problems caused by using an unsuitable filler during high-temperature baking may include:
JLTL BPO 280°C filler is formulated for approximately 280°C short-term exposure during the powder-coating process.
280°C is a short-term process temperature rating, not a continuous service-temperature rating.
It should not be specified for components that remain continuously exposed to 280°C or higher.
For electrostatic powder coating, electrical behavior matters.
When a conventional insulating filler is used on a conductive metal workpiece, the repaired area may behave differently from the surrounding substrate during powder deposition.
This product uses a conductive formulation intended for electrostatic powder-coating applications.
It is therefore particularly suitable when the repair area needs to proceed into a powder-coating line after sanding and surface preparation.
The actual powder deposition result remains dependent on the complete production process, including grounding, pretreatment, powder system, spray equipment and baking conditions.
Many industrial manufacturers process more than one type of metal.
One production line may handle:
Steel + Phosphated Steel + Aluminum + Stainless Steel
Using different repair fillers for every substrate can increase material management complexity.
JLTL BPO high-temperature conductive filler is designed for multiple industrial metal substrates.
Proper degreasing, sanding and surface preparation remain essential.
Aluminum castings can contain small imperfections that become highly visible after powder coating.
Common defects include:
Using a suitable high-temperature repair filler before powder coating allows these defects to be corrected before the final coating stage.
Aluminum Casting
→ Degrease
→ Sand / Mechanically Prepare
→ Apply BPO Filler
→ Cure
→ Sand Smooth
→ Electrostatic Powder Coating
→ High-Temperature Baking
This makes the product particularly relevant to aluminum casting manufacturers and industrial component suppliers.
For manufacturers of industrial equipment, surface defects can occur during fabrication.
Typical causes include:
The filler can be used to repair suitable surface defects on:
After curing and sanding, the repaired component can proceed to the powder-coating stage.
Powder coating is widely used for metal products requiring a combination of appearance and surface protection.
Potential applications include:
Small welding marks, dents, holes and surface imperfections can be repaired before powder coating to help achieve a more uniform finished surface.
The product can also be considered for compatible automotive and motorcycle components that will subsequently receive powder coating.
Potential applications include:
The specific component must be suitable for the complete powder-coating and baking process.
| Defect | Typical Application |
| Casting Porosity | Aluminum and metal castings |
| Pinholes | Castings and fabricated metal |
| Small Cavities | Metal surface leveling |
| Weld Marks | Fabricated steel components |
| Scratches | Machined / handled components |
| Small Dents | Metal panels and housings |
| Casting Defects | Aluminum and iron castings |
| Surface Irregularities | Pre-powder-coating preparation |
The product is primarily intended for surface defect filling and leveling, not structural repair.
A high-temperature industrial filler needs to work not only in the oven but also on the factory floor.
JLTL BPO high-temperature conductive filler is designed for:
Convenient manual application for localized surface defects.
Suitable for small holes, porosity, dents and surface imperfections.
Allows operators to level and shape the repaired area before final sanding.
Supports efficient surface preparation before powder coating.
For deeper defects, multiple thinner applications are recommended instead of applying an excessively thick single layer.
Body Filler : BPO Hardener = 100 : 2 by weight
The hardener supplied for this product is red.
For consistent production results, accurate weighing and thorough mixing are recommended.
Avoid introducing excessive hardener or using an uncontrolled ratio, as the curing behavior and final properties may be affected.
Remove oil, grease, dust, rust and loose material.
Sand or otherwise mechanically prepare the metal substrate.
Mix the filler and red BPO hardener at 100:2 by weight.
Fill the required defect and level the surface.
Allow the filler to cure under appropriate ambient conditions.
Sand the repaired area to the required smoothness.
Apply the compatible powder coating electrostatically.
Proceed with the specified high-temperature powder-coating baking process.

Choose according to the actual production conditions.
For standard industrial powder coating around the lower temperature range: A suitable CHPO high-temperature filler may provide better cost efficiency.
For applications requiring approximately 280°C short-term exposure and conductive performance: JLTL BPO 280°C High Temperature Conductive Body Filler is the more targeted option.
This product is not automatically the best choice for every application.
If the repair only involves normal automotive painting and relatively low-temperature curing, a standard automotive body filler may be more economical.
If the workpiece does not enter an electrostatic powder-coating process, the conductive formulation may not provide a meaningful process advantage.
Do not use the 280°C figure as a continuous service-temperature specification.
Deep defects should be repaired in suitable layers rather than through an excessively thick single application.
For pre-treatment and surface correction before powder spraying.
For correcting porosity, pinholes and small casting defects.
For improving the surface condition before decorative powder coating.
For repairing welding and fabrication imperfections.
For machine housings, frames and fabricated metal components.
For surface leveling before final powder coating.
For suitable metal parts requiring powder-coated finishing.
For supplying specialized high-temperature repair materials to manufacturing customers.
